-<h1>Installing Moodle</h1>
-<blockquote>
-  <p>This guide explains how to install Moodle for the first time.  It goes into some detail
-   about some of the steps, in order to cover the wide variety of small differences between
-   web server setups, so this document may look long and complicated.  Don't be put off by this 
-   - I usually set Moodle up in a few minutes!</p>
-  <p>Take your time and work through this document carefully - it will save you time later on.</p>

-<h3 class="sectionheading"><a name="requirements"></a>1. Requirements</h3>
-<blockquote> 
-  <p>Moodle is primarily developed in Linux using Apache, MySQL and PHP (also 
-    sometimes known as the LAMP platform), but is also regularly tested with PostgreSQL 
-    and on Windows XP, Mac OS X and Netware 6 operating systems</p>
-  <p>The requirements for Moodle are as follows:</p>
-  <ol>
-    <li>Web server software. Most people use <a href="http://www.apache.org/" target="_blank">Apache</a>, 
-      but Moodle should work fine under any web server that supports PHP, such 
-      as IIS on Windows platforms.</li>
-    <li><a href="http://www.php.net/" target="_blank">PHP</a> scripting language (version 4.1.0 
-      or later), with the following settings: 
-      <ul>
-        <li><a href="http://www.boutell.com/gd/" target="_blank">GD library</a> 
-          turned ON, with support for JPG and PNG formats</li>
-        <li>zlib library turned ON (if you want to use backup/restore on Windows)</li>
-        <li>Sessions support turned ON</li>
-        <li>File uploading turned ON</li>
-        <li>Safe Mode must be turned OFF (see the forums on moodle.org for problems 
-          caused by Safe Mode)</li>
-      </ul>
-    </li>
-    <li>a working database server: <a href="http://www.mysql.com/" target="_blank">MySQL</a> 
-      or <a href="http://www.postgresql.org/" target="_blank">PostgreSQL</a> are 
-      completely supported and recommended for use with Moodle 1.1. All other 
-      databases will be supported fully in the next release.</li>
-  </ol>
-  <p>Most web hosts support all of this by default. If you are signed up with 
-    one of the few webhosts that does not support these features ask them why, 
-    and consider taking your business elsewhere.</p>
-  <p>If you want to run Moodle on your own computer and all this looks a bit daunting, 
-    then please see our guide: <a href="http://moodle.org/doc/?file=installamp.html">Installing 
-    Apache, MySQL and PHP</a>. It provides some step-by-step instructions to install 
-    all this on most popular platforms.</p>
-  <p>&nbsp;</p>
-</blockquote>
-<h3 class="sectionheading"><a name="downloading"></a>2. Download</h3>
-<blockquote>
-  <p>There are two ways to get Moodle, as a compressed package and via CVS. These 
-    are explained in detail on the download page: <a href="http://moodle.org/download/" target="_blank">http://moodle.org/download/</a></p>
-  <p>After downloading and unpacking the archive, or checking out the files via 
-    CVS, you will be left with a directory called &quot;moodle&quot;, containing 
-    a number of files and folders. </p>
-  <p>You can either place the whole folder in your web server documents directory, 
-    in which case the site will be located at <b>http://yourwebserver.com/moodle</b>, 
-    or you can copy all the contents straight into the main web server documents 
-    directory, in which case the site will be simply <b>http://yourwebserver.com</b>.</p>
-</blockquote>
-<p>&nbsp;</p>
-<h3 class="sectionheading"><a name="site"></a>3. Site structure</h3>
-<blockquote>
-  <p>Here is a quick summary of the contents of the Moodle folder, to help get 
-    you oriented:</p>
-  <blockquote>
-    <p>config.php - the ONLY file you need to edit to get started<br />
-      version.php - defines the current version of Moodle code<br />
-      index.php - the front page of the site</p>
-    <ul>
-      <li>admin/ - code to administrate the whole server </li>
-      <li>auth/ - plugin modules to authenticate users  </li>
-      <li>course/ - code to display and manage courses </li>
-      <li>doc/ - help documentation for Moodle (eg this page)</li>
-      <li>files/ - code to display and manage uploaded files</li>
-      <li>lang/ - texts in different languages, one directory per language </li>
-      <li>lib/ - libraries of core Moodle code </li>
-      <li>login/ - code to handle login and account creation </li>
-      <li>mod/ - all Moodle course modules</li>
-      <li>pix/ - generic site graphics</li>
-      <li>theme/ - theme packs/skins to change the look of the site.</li>
-      <li>user/ - code to display and manage users</li>
-    </ul>
-    <p>&nbsp;</p>
-  </blockquote>
-</blockquote>
-<h3 class="sectionheading"><a name="data"></a>4. Create a data directory</h3>
-<blockquote>
-  <p>Moodle will also need some space on your hard disk to store uploaded files, 
-    such as course documents and user pictures.</p>
-  <p>Create a directory for this purpose somewhere.  For security, it's best that 
-     this directory is NOT accessible directly via the web.  The easiest way to do this
-     is to simply locate it OUTSIDE the web directory, otherwise protect it 
-     by creating a file in the data directory called .htaccess, containing this line:
-  <blockquote>
-     
-    <pre>deny from all<br />AllowOverride None</pre>
-  </blockquote>
-  <p>To make sure that Moodle can save uploaded files in this directory, check that 
-     the web server software (eg Apache) has permission to write 
-    to this directory. On Unix machines, this means setting the owner of the directory 
-    to be something like &quot;nobody&quot; or &quot;apache&quot;.</p>
-  <p>On many shared hosting servers, you will probably need to restrict all file access 
-     to your "group" (to prevent other webhost customers from looking at or changing your files), 
-     but provide full read/write access to everyone else (which will allow the web server
-     to access your files).  Speak to your server administrator if you are having 
-     trouble setting this up securely.</p>

-<h3 class="sectionheading"><a name="database"></a>5. Create a database</h3>
-<blockquote>
-  <p>You need to create an empty database (eg "moodle") in your database system 
-    along with a special user (eg "moodleuser") that has access to that database 
-    (and that database only). You could use the "root" user if you wanted to, but 
-    this is not recommended for a production system: if hackers manage to discover
-    the password then your whole database system would be at risk, rather than 
-    just one database.
-</p>
-  <p>Example command lines for MySQL: </p>
-  <pre>
-   # mysql -u root -p
-   > CREATE DATABASE moodle; 
-   > GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP,INDEX,ALTER ON moodle.* 
-           TO moodleuser@localhost IDENTIFIED BY 'yourpassword'; 
-   > quit 
-   # mysqladmin -p reload
-</pre>
-  <p>Example command lines for PostgreSQL: </p>
-  <pre>
-   # su - postgres
-   > psql -c "create user moodleuser createdb;" template1
-   > psql -c "create database moodle;" -U moodleuser template1
-   > psql -c "alter user moodleuser nocreatedb;" template1
-</pre>
-  <p>(For MySQL I highly recommend the use of <a href="http://phpmyadmin.sourceforge.net/">phpMyAdmin</a> 
-    to manage your databases - you can do all this via a web interface).</p>
-  <p>As of version 1.0.8, Moodle now supports table prefixes, and so can safely share 
-   a database with tables from other applications.</p>
-</blockquote>
-<p>&nbsp;</p>
-<h3 class="sectionheading"><a name="webserver" id="webserver"></a>6. Check your web server settings</h3>
-<blockquote>
-  <p>Firstly, make sure that your web server is set up to use index.php as a default 
-    page (perhaps in addition to index.html, default.htm and so on).</p>
-  <p>In Apache, this is done using a DirectoryIndex parameter in your httpd.conf 
-    file. Mine usually looks like this:</p>
-  <blockquote>
-    <pre><strong>DirectoryIndex</strong> index.php index.html index.htm </pre>
-  </blockquote>
-  <p>Just make sure index.php is in the list (and preferably towards the start 
-    of the list, for efficiency).</p>
-  <p>Secondly, <b>if you are using Apache 2</b>, then you should turn on the <i>AcceptPathInfo</i>
-     variable, which allows scripts to be passed arguments like http://server/file.php/arg1/arg2.
-     This is essential to allow relative links between your resources, and also 
-     provides a performance boost for people using your Moodle web site.  You can 
-     turn this on by adding these lines to your httpd.conf file.</p>
-  <blockquote>
-    <pre><strong>AcceptPathInfo</strong> on </pre>
-  </blockquote>
-  <p>Thirdly, Moodle requires a number of PHP settings to be active for it to 
-     work.  <b>On most servers these will already be the default settings.</b>
-     However, some PHP servers (and some of the more recent PHP versions) may 
-     have things set differently.  These are defined in PHP's configuration
-     file (usually called php.ini):</p>
-  <blockquote>
-
-    <pre>magic_quotes_gpc = 1    (preferred but not necessary)
-magic_quotes_runtime = 0    (necessary)
-file_uploads = 1
-session.auto_start = 0
-session.bug_compat_warn = 0
-</pre>
-  </blockquote>
-  <p>If you don't have access to httpd.conf or php.ini on your server, or you 
-    have Moodle on a server with other applications that require different settings, 
-    then don't worry, you can still OVERRIDE all of the default settings. 
-  <p>To do this, you need to create a file called <b>.htaccess</b> in Moodle's
-     main directory that contains definitions for these settings.
-     This only works on Apache servers and only when Overrides have been allowed.
-     
-  <blockquote>
-    <pre>
-DirectoryIndex index.php index.html index.htm
-
-&lt;IfDefine APACHE2>
-     <b>AcceptPathInfo</b> on
-&lt;/IfDefine>
-
-php_flag magic_quotes_gpc 1
-php_flag magic_quotes_runtime 0
-php_flag file_uploads 1
-php_flag session.auto_start 0
-php_flag session.bug_compat_warn 0</pre>
-  </blockquote>
-  <p>You can also do things like define the maximum size for uploaded files:
-     
-  <blockquote>
-    <pre>
-LimitRequestBody 0
-php_value upload_max_filesize 2M
-php_value post_max_size 2M
-     </pre>
-  </blockquote>
-  <p>The easiest thing to do is just copy the sample file from lib/htaccess 
-     and edit it to suit your needs.  It contains further instructions.  For 
-     example, in a Unix shell:
-  <blockquote>
-    <pre>cp lib/htaccess .htaccess</pre>
-  </blockquote>
-</blockquote>
-<p>&nbsp;</p>
-<h3 class="sectionheading"><a name="config"></a>7. Edit config.php</h3>
-<blockquote>
-  <p>Now you can edit the configuration file, <strong>config.php</strong>, using a 
-     text editor. This file is used by all other files in Moodle.</p>
-  <p>To start with, make a copy of <strong>config-dist.php</strong> and name it 
-    config.php. We do this so that your config.php won't be overwritten in case 
-    you upgrade Moodle later on. </p>
-  <p>Edit <strong>config.php</strong> to specify the database details that you 
-    just defined (including a table prefix - notice that this is REQUIRED for 
-    PostgreSQL), as well as the site address, file system directory and data directory. 
-    The config file itself has detailed directions and examples.</p>
-  <p>Once you have done this the rest of the installation is via a web interface. 
-    For the rest of this installation document we will assume your site is at: 
-    <u>http://example.com/moodle</u></p>
-</blockquote>
-<p>&nbsp;</p>
-<h3 class="sectionheading"><a name="admin"></a>8. Go to the admin page</h3>
-<blockquote> 
-  <p>The admin page should now be working at: <u>http://example.com/moodle/admin</u>. 
-    If you try and access the front page of your site you'll be taken there automatically 
-    anyway. The first time you access this admin page, you will be presented with 
-    a GPL &quot;shrinkwrap&quot; agreement with which you must agree before you 
-    can continue with the setup.</p>
-  <p>(Moodle will also try to set some cookies in your browser. If you have your 
-    browser set up to let you choose to accept cookies, then you <b>must</b> accept 
-    the Moodle cookies, or Moodle won't work properly.) 
-  <p>Now Moodle will start setting up your database and creating tables to store 
-    data. Firstly, the main database tables are created. You should see a number 
-    of SQL statements followed by status messages (in green or red) that look 
-    like this:</p>
-  <blockquote> 
-    <p>CREATE TABLE course ( id int(10) unsigned NOT NULL auto_increment, category 
-      int(10) unsigned NOT NULL default '0', password varchar(50) NOT NULL default 
-      '', fullname varchar(254) NOT NULL default '', shortname varchar(15) NOT 
-      NULL default '', summary text NOT NULL, format tinyint(4) NOT NULL default 
-      '1', teacher varchar(100) NOT NULL default 'Teacher', startdate int(10) 
-      unsigned NOT NULL default '0', enddate int(10) unsigned NOT NULL default 
-      '0', timemodified int(10) unsigned NOT NULL default '0', PRIMARY KEY (id)) 
-      TYPE=MyISAM</p>
-    <p><font color="#006600">SUCCESS</font></p>
-    <p>...and so on, followed by: <font color="#006600">Main databases set up 
-      successfully.</font> </p>
-  </blockquote>
-  <p>If you don't see these, then there must have been some problem with the database 
-    or the configuration settings you defined in config.php. Check that PHP isn't 
-    in a restricted "Safe Mode" (commercial web hosts sometimes have safe mode 
-    turned on). You can check PHP variables by creating a little file containing 
-    &lt? phpinfo() ?&gt and looking at it through a browser. Check all these and 
-    try this page again.</p>
-  <p>Scroll down the very bottom of the page and press the &quot;Continue&quot; 
-    link.</p>
-  <p>Next you will see a similar page that sets up all the tables required by 
-    each Moodle module. As before, they should all be <font color="#006600">green</font>.</p>
-  <p>Scroll down the very bottom of the page and press the &quot;Continue&quot; 
-    link.</p>
-  <p>You should now see a form where you can define more configuration variables 
-    for your installation, such as the default language, SMTP hosts and so on. 
-    Don't worry too much about getting everything right just now - you can always 
-    come back and edit these later on using the admin interface. Scroll down to 
-    the bottom and click &quot;Save changes&quot;.</p>
-  <p>If (and only if) you find yourself getting stuck on this page, unable to 
-    continue, then your server probably has what I call the "buggy referrer" problem. 
-    This is easy to fix: just turn off the &quot;secureforms&quot; setting, then 
-    try to continue again.</p>
-  <p>The next page is a form where you can define parameters for your Moodle site 
-    and the front page, such as the name, format, description and so on. Fill 
-    this out (you can always come back and change these later) and then press 
-    &quot;Save changes&quot;.</p>
-  <p>Finally, you will then be asked to create a top-level administration user 
-    for future access to the admin pages. Fill out the details with your own name, 
-    email etc and then click &quot;Save changes&quot;. Not all the fields are 
-    required, but if you miss any important fields you'll be re-prompted for them. 
-  </p>
-  <blockquote> 
-    <blockquote> 
-      <blockquote> 
-        <blockquote> 
-          <blockquote> 
-            <p><strong>Make sure you remember the username and password you chose 
-              for the administration user account, as they will be necessary to 
-              access the administration page in future.</strong></p>
-          </blockquote>
-        </blockquote>
-      </blockquote>
-    </blockquote>
-  </blockquote>
-  <p>(If for any reason your install is interrupted, or there is a system error 
-    of some kind that prevents you from logging in using the admin account, you 
-    can usually log in using the default username of &quot;<strong>admin</strong>&quot;, 
-    with password &quot;<strong>admin</strong>&quot;.)</p>
-  <p>Once successful, you will be returned to home page of your site. Note the 
-    administration links that appear down the left hand side of the page (these 
-    items also appear on a separate Admin page) - these items are only visible 
-    to you because you are logged in as the admin user. All your further administration 
-    of Moodle can now be done using this menu, such as:</p>
-  <ul>
-    <li>creating and deleting courses</li>
-    <li>creating and editing user accounts</li>
-    <li>administering teacher accounts</li>
-    <li>changing site-wide settings like themes etc</li>
-  </ul>
-</blockquote>
-<p>&nbsp;</p>
-<h3 class="sectionheading"><a name="cron"></a>9. Set up cron</h3>
-<blockquote> 
-  <p>Some of Moodle's modules require continual checks to perform tasks. For example, 
-    Moodle needs to check the discussion forums so it can mail out copies of posts 
-    to people who have subscribed.</p>
-  <p>The script that does all this is located in the admin directory, and is called 
-    cron.php. However, it can not run itself, so you need to set up a mechanism 
-    where this script is run regularly (eg every five or ten minutes). This provides 
-    a &quot;heartbeat&quot; so that the script can perform functions at periods 
-    defined by each module.</p>
-  <p>Note that the machine performing the cron <b>does not need to be the same 
-    machine that is running Moodle</b>. For example, if you have a limited web 
-    hosting service that does not have cron, then you can might choose to run 
-    cron on another server or on your home computer. All that matters is that 
-    the cron.php file is called regularly. </p>
-  <p>The load of this script is not very high, so 5 minutes is usually reasonable, 
-    but if you're worried about it you can reduce the time period to something 
-    like 15 minutes or even 30 minutes. It's best not to make the time period 
-    too long, as delaying mail-outs can slow down activity within the course.</p>
-  <p>First, test that the script works by running it directly from your browser:</p>
-  <blockquote> 
-    <pre>http://example.com/moodle/admin/cron.php</pre>
-  </blockquote>
-  <p>Now, you need to set up some of way of running the script automatically and 
-    regularly. </p>
-  <h4> Running the script from a command line</h4>
-  <p>You can call the page from the command line just as you did in the example 
-    above. For example, you can use a Unix utility like 'wget':</p>
-  <blockquote>
-    <pre>wget -q -O /dev/null http://example.com/moodle/admin/cron.php</pre>
-  </blockquote>
-  <p>Note in this example that the output is thrown away (to /dev/null).</p>
-  <p>The same thing using lynx:</p>
-  <blockquote>
-    <pre>lynx -dump http://example.com/moodle/admin/cron.php &gt; /dev/null</pre>
-  </blockquote>
-  <p>Alternatively you could use a standalone version of PHP, compiled to be run 
-    on the command line. The advantage with doing this is that your web server 
-    logs aren't filled with constant requests to cron.php. The disadvantage is 
-    that you need to have access to a command-line version of php.</p>
-  <blockquote>
-    <pre>/opt/bin/php /web/moodle/admin/cron.php
-
-
-(Windows) C:\apache\php\php.exe C:\apache\htdocs\moodle\admin\cron.php
-
-</pre>
-  </blockquote>
-  <h4>Automatically running the script every 5 minutes</h4>
-  <p><b>On Unix systems</b>: Use <b>cron</b>. Edit your cron settings from the commandline 
-    using &quot;crontab -e&quot; and add a line like:</p>
-  <blockquote>
-    <pre>*/5 * * * * wget -q -O /dev/null http://example.com/moodle/admin/cron.php</pre>
-  </blockquote>
-  <p>Usually, the "crontab" command will put you into the 'vi' editor. You enter 
-     "insert mode" by pressing "i", then type in the line as above, then exit insert mode by 
-     pressing ESC.  You save and exit by typing ":wq", or quit without saving using ":q!" (without the quotes).</p>
-  <p><b>On Windows systems</b>: The simplest way is to use this little package <a href="http://moodle.org/download/moodle-cron-for-windows.zip" title="Click to download this package (150k)" target="_blank">moodle-cron-for-windows.zip</a> 
-    which makes this whole thing very easy. You can also explore using the built-in 
-    Windows feature for "Scheduled Tasks".</p>
-  <p>On web hosts: Your web-based control panel may have a web page that allows 
-    you to set up this cron process. Ask your administrator for details on how 
-    it works.</p>
-  <p></p>
-</blockquote>
-<h3 class="sectionheading"><a name="course"></a>10. Create a new course</h3>
-<blockquote>
-  <p>Now that Moodle is running properly, you can create a course. </p>
-  <p>Select &quot;Create a new course&quot; from the Admin page (or the admin 
-    links on the home page).</p>
-  <p>Fill out the form, paying special attention to the course format. You don't 
-    have to worry about the details too much at this stage, as everything can 
-    be changed later by the teacher.</p>
-  <p>Press &quot;Save changes&quot;, and you will be taken to a new form where 
-    you can assign teachers to the course. You can only add existing user accounts 
-    from this form - if you want to create a new teacher account then either ask 
-    the teacher to create one for themselves (see the login page), or create one 
-    for them using the &quot;Add a new user&quot; on the Admin page.</p>
-  <p>Once done, the course is ready to customise, and is accessible via the &quot;Courses&quot; 
-    link on the home page.</p>
-  <p>See the &quot;<a href="./?file=teacher.html">Teacher Manual</a>&quot; for more details 
-    on course-building.</p>

-  Latest version of ADODB is available at http://php.weblogs.com/adodb
-  ======================================================================
-  
- This file provides PHP4 session management using the ADODB database
-wrapper library.
- 
- Example
- =======
- 
- 	GLOBAL $HTTP_SESSION_VARS;
-	include('adodb.inc.php');
-	#---------------------------------#
-	include('adodb-cryptsession.php'); 
-	#---------------------------------#
-	session_start();
-	session_register('AVAR');
-	$HTTP_SESSION_VARS['AVAR'] += 1;
-	print "<p>\$HTTP_SESSION_VARS['AVAR']={$HTTP_SESSION_VARS['AVAR']}</p>";
-
- 
- Installation
- ============
- 1. Create a new database in MySQL or Access "sessions" like
-so:
- 
-  create table sessions (
-	   SESSKEY char(32) not null,
-	   EXPIRY int(11) unsigned not null,
-	   EXPIREREF varchar(64),
-	   DATA CLOB,
-	  primary key (sesskey)
-  );
-  
-  2. Then define the following parameters. You can either modify
-     this file, or define them before this file is included:
-	 
-  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
-	$ADODB_SESSION_CONNECT='server to connect to';
-	$ADODB_SESSION_USER ='user';
-	$ADODB_SESSION_PWD ='password';
-	$ADODB_SESSION_DB ='database';
-	$ADODB_SESSION_TBL = 'sessions'
-	
-  3. Recommended is PHP 4.0.2 or later. There are documented
-session bugs in earlier versions of PHP.

-  ======================================================================
-  
- This file provides PHP4 session management using the ADODB database
- wrapper library, using Oracle CLOB's to store data. Contributed by achim.gosse@ddd.de.

- 
- 	GLOBAL $HTTP_SESSION_VARS;
-	include('adodb.inc.php');
-	include('adodb-session.php');
-	session_start();
-	session_register('AVAR');
-	$HTTP_SESSION_VARS['AVAR'] += 1;
-	print "<p>\$HTTP_SESSION_VARS['AVAR']={$HTTP_SESSION_VARS['AVAR']}</p>";
-	
-To force non-persistent connections, call adodb_session_open first before session_start():
-
- 	GLOBAL $HTTP_SESSION_VARS;
-	include('adodb.inc.php');
-	include('adodb-session.php');
-	adodb_session_open(false,false,false);
-	session_start();
-	session_register('AVAR');
-	$HTTP_SESSION_VARS['AVAR'] += 1;
-	print "<p>\$HTTP_SESSION_VARS['AVAR']={$HTTP_SESSION_VARS['AVAR']}</p>";

- Installation
- ============
- 1. Create this table in your database (syntax might vary depending on your db):
- 
-  create table sessions (
-	   SESSKEY char(32) not null,
-	   EXPIRY int(11) unsigned not null,
-	   EXPIREREF varchar(64),
-	   DATA CLOB,
-	  primary key (sesskey)
-  );
-
-
-  2. Then define the following parameters in this file:
-  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
-	$ADODB_SESSION_CONNECT='server to connect to';
-	$ADODB_SESSION_USER ='user';
-	$ADODB_SESSION_PWD ='password';
-	$ADODB_SESSION_DB ='database';
-	$ADODB_SESSION_TBL = 'sessions'
-	$ADODB_SESSION_USE_LOBS = false; (or, if you wanna use CLOBS (= 'CLOB') or ( = 'BLOB')
-	
-  3. Recommended is PHP 4.0.6 or later. There are documented
-	 session bugs in earlier versions of PHP.
-
-  4. If you want to receive notifications when a session expires, then
-  	 you can tag a session with an EXPIREREF, and before the session
-	 record is deleted, we can call a function that will pass the EXPIREREF
-	 as the first parameter, and the session key as the second parameter.
-	 
-	 To do this, define a notification function, say NotifyFn:
-	 
-	 	function NotifyFn($expireref, $sesskey)
-	 	{
-	 	}
-	 
-	 Then you need to define a global variable $ADODB_SESSION_EXPIRE_NOTIFY.
-	 This is an array with 2 elements, the first being the name of the variable
-	 you would like to store in the EXPIREREF field, and the 2nd is the 
-	 notification function's name.
-	 
-	 In this example, we want to be notified when a user's session 
-	 has expired, so we store the user id in the global variable $USERID, 
-	 store this value in the EXPIREREF field:
-	 
-	 	$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
-		
-	Then when the NotifyFn is called, we are passed the $USERID as the first
-	parameter, eg. NotifyFn($userid, $sesskey).

-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice
-
-That's all there is to it!

-<P>Written by <a href="mailto:richtl@arscognita.com">Richard Tango-Lowy</a>.</P>
-<P>For more information, contact <a href="richtl@arscognita.com">richtl@arscognita.com</a> 
-or visit our site at <a href="http://www.arscognita.com">www.arscognita.com</a>.</P>
-<P>At the moment, you should report bugs by mailing them to me. (If I can't convince John to
-make this part of ADODB :-), I'll  create a project for it on SourceForge.)
-
-<H2>Introduction</H2>
-<P><B>adodb-xmlschema</B> is a class that allows the user to quickly and easily
-build a database on any ADOdb-supported platform using a simple XML format.</P>
-<P>This library is dual-licensed under a BSD-style license and under the <B><a href="http://opensource.org/licenses/lgpl-license.php">GNU Lesser Public License</a></B>.
-See the <B>LICENSE</B> file for more information.</P>
-
-<H2>Features</H2><UL>
-	<LI>Darned easy to install
-	<LI>Quickly to create schemas that build on any platform supported by ADODB.</UL>
-
-<H2>Installation</H2>
-<P>To install adodb-xmlschema, simply copy the <tt>adodb-xmlschema.php</tt> file into your
-<B>ADODB</B> directory.</P>
-
-<H2>Quick Start</H2>
-<P>First, create an XML database schema. Let's call it "schema.xml:"</P><PRE>
-&lt;?xml version="1.0"?&gt;
-&lt;schema&gt;
-  &lt;table name="mytable"&gt;
-    &lt;field name="row1" type="I"&gt;
-      &lt;descr&gt;An integer row that's a primary key and autoincrements&lt;/descr&gt;
-      &lt;KEY/&gt;
-      &lt;AUTOINCREMENT/&gt;
-    &lt;/field&gt;
-    &lt;field name="row2" type="C" size="16"&gt;
-      &lt;descr&gt;A 16 character varchar row that can't be null&lt;/descr&gt;
-      &lt;NOTNULL/&gt;
-    &lt;/field&gt;
-  &lt;/table&gt;
-  &lt;index name="myindex" table="mytable"&gt;
-    &lt;col&gt;row1&lt;/col&gt;
-    &lt;col&gt;row2&lt;/col&gt;
-  &lt;/index&gt;
-  &lt;sql&gt;
-    &lt;descr&gt;SQL to be executed only on specific platforms&lt;/descr&gt;
-    &lt;query platform="postgres|postgres7"&gt;
-      insert into mytable ( row1, row2 ) values ( 12, 'stuff' )
-    &lt;/query&gt;
-    &lt;query platform="mysql"&gt;
-      insert into mytable ( row1, row2 ) values ( 12, 'different stuff' )
-    &lt;/query&gt;
-  &lt;/sql&gt;
-&lt;/schema&gt;
-</PRE><P>Create a new database using the appropriate tool for your platform.
-Executing the following PHP code will create the a <i>mytable</i> and <i>myindex</i>
-in the database and insert two rows into <i>mytable</i>. </P><PRE>				
-// To build the schema, start by creating a normal ADOdb connection:
-$db->NewADOConnection( 'mysql' );
-$db->Connect( ... );
-
-// Create the schema object and build the query array.
-$schema = <B>new adoSchema</B>( $db );
-
-// Build the SQL array
-$sql = $schema-><B>ParseSchema</B>( "schema.xml" );
-
-// Execute the SQL on the database
-$result = $schema-><B>ExecuteSchema</B>( $sql );
-
-// Finally, clean up after the XML parser
-// (PHP won't do this for you!)
-$schema-><B>Destroy</B>();
-</PRE>
-	
-<H2>XML Schema Format:</H2>
-<P>(See <a href="../xmlschema.dtd">ADOdb_schema.dtd</a> for the full specification)</P>
-<PRE>
-&lt;?xml version="1.0"?&gt;
-&lt;schema&gt;
-  &lt;table name="tablename" platform="platform1|platform2|..."&gt;
-    &lt;descr&gt;Optional description&lt;/descr&gt;
-    &lt;field name="fieldname" type="datadict_type" size="size"&gt;
-      &lt;KEY/&gt;
-      &lt;NOTNULL/&gt;
-      &lt;AUTOINCREMENT/&gt;
-      &lt;DEFAULT value="value"/&gt;
-    &lt;/field&gt;
-	... <i>more fields</i>
-  &lt;/table&gt;
-  ... <i>more tables</i>
-  
-  &lt;index name="indexname" platform="platform1|platform2|..."&gt;
-    &lt;descr&gt;Optional description&lt;/descr&gt;
-    &lt;col&gt;fieldname&lt;/col&gt;
-    ... <i>more columns</i>
-  &lt;/index&gt;
-  ... <i>more indices</i>
-  
-  &lt;sql platform="platform1|platform2|..."&gt;
-    &lt;descr&gt;Optional description&lt;/descr&gt;
-    &lt;query platform="platform1|platform2|..."&gt;SQL query&lt;/query&gt;
-    ... <i>more queries</i>
-  &lt;/sql&gt;
-  ... <i>more SQL</i>
-  &lt;/schema&gt;

-<HR>
-<H2>Thanks</H2>
-<P>Thanks to John Lim for giving us ADODB, and for the hard work that keeps it on top of things. 
-And particulary for the datadict code that made xmlschema possible.</P>
-<P>And to the kind folks at <a href="http://phpdoc.org">PHP Documentor</a>. Cool tool.</P>
-<P>And to Linus. I thought the end of Amiga was the end of computing. Guess I was wrong :-)</P>

-
-<H2>Installation</H2>
-<P>To install adodb-xmlschema, simply copy the <tt>adodb-xmlschema.php</tt> file into your
-<B>ADODB</B> directory.</P>
-
-<H2>Quick Start</H2>
-<P>First, create an XML database schema. Let's call it "schema.xml:"</P><PRE>
-&lt;?xml version="1.0"?&gt;

-      insert into mytable ( row1, row2 ) values ( 12, 'different stuff' )
-    &lt;/query&gt;
-  &lt;/sql&gt;

-<P>Thanks to John Lim for giving us ADODB, and for the hard work that keeps it on top of things.

-  <a href="#adodiff">Differences between ADOdb and ADO</a><br>
-  <a href="#driverguide"><b>Database Driver Guide<br>
-  </b></a><b><a href="#changes">Change Log</a></b><br>
-</p>
-<h2>Introduction<a name="intro"></a></h2>
-<p>PHP's database access functions are not standardised. This creates a need for 
-  a database class library to hide the differences between the different database 
-  API's (encapsulate the differences) so we can easily switch databases. PHP 4.0.5 or later
-  is now required (because we use array-based str_replace).</p>
-<p>We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL Anywhere, Informix, 
-  PostgreSQL, FrontBase,  SQLite, Interbase (Firebird and Borland variants), Foxpro, Access, ADO, DB2, SAP DB and ODBC. 
-  We have had successful reports of connecting to Progress and CacheLite via ODBC. We hope more people 
-  will contribute drivers to support other databases.</p>
-<p>PHP4 supports session variables. You can store your session information using 
-  ADOdb for true portability and scalability. See adodb-session.php for more information.</p>
-<p>Also read <a href="http://php.weblogs.com/portable_sql">http://php.weblogs.com/portable_sql</a> 
-  (also available as tips_portable_sql.htm in the release) for tips on writing 
-  portable SQL.</p>
-<h2>Unique Features of ADOdb<a name="features"></a></h2>
-<ul>
-  <li><b>Easy for Windows programmers</b> to adapt to because many of the conventions 
-	are similar to Microsoft's ADO.</li>
-  <li>Unlike other PHP database classes which focus only on select statements, 
-	<b>we provide support code to handle inserts and updates which can be adapted 
-	to multiple databases quickly.</b> Methods are provided for date handling, 
-	string concatenation and string quoting characters for differing databases.</li>
-  <li>A<b> metatype system </b>is built in so that we can figure out that types 
-	such as CHAR, TEXT and STRING are equivalent in different databases.</li>
-  <li><b>Easy to port</b> because all the database dependant code are stored in 
-	stub functions. You do not need to port the core logic of the classes.</li>
-  <li><b>Portable table and index creation</b> with the <a href=docs-datadict.htm>datadict</a> classes.
-  <li><b>Database performance monitoring and SQL tuning</b> with the <a href=docs-perf.htm>performance monitoring</a> classes.
-  <li><b>Database-backed sessions</b> with the <a href=docs-session.htm>session management</a> classes. Supports session expiry notification.
-</ul>
-<h2>How People are using ADOdb<a name="users"></a></h2>
-Here are some examples of how people are using ADOdb (for a much longer list, 
-visit <a href="http://php.weblogs.com/adodb-cool-applications">http://php.weblogs.com/adodb-cool-applications</a>): 
-<ul>
-<li><a href="http://phplens.com/">PhpLens</a> is a commercial data grid component that allows both cool Web designers and serious unshaved programmers to develop and maintain databases on the Web easily. Developed by the author of ADOdb.<p>
-
-<li><a href="http://www.interakt.ro/phakt/">PHAkt: PHP Extension for DreamWeaver Ultradev</a> allows you to script PHP in the popular Web page editor. Database handling provided by ADOdb.<p>

By Roman Danyliw.<p>
-
-<li><a href="http://www.postnuke.com/">PostNuke</a> is a very popular free content management
- system and weblog system. It offers full CSS support, HTML 4.01 transitional compliance throughout, an advanced blocks system, and is fully multi-lingual enabled. <p>

-</ul><p>
-
-<h2>Feature Requests and Bug Reports<a name="bugs"></a></h2>
-<p>Feature requests and bug reports can be emailed to <a href="mailto:jlim#natsoft.com.my">jlim#natsoft.com.my</a> 
-  or posted to the ADOdb Help forums at <a href="http://phplens.com/lens/lensforum/topics.php?id=4">http://phplens.com/lens/lensforum/topics.php?id=4</a>.</p>
-<h2>Installation Guide<a name="install"></a></h2>
-<p>Make sure you are running PHP 4.0.4 or later. 
-  Unpack all the files into a directory accessible by your webserver.</p>
-<p>To test, try modifying some of the tutorial examples. Make sure you customize 
-  the connection settings correctly. You can debug using <i>$db->debug = true</i> as shown below:</p>
-<pre>&lt;?php
-	include('adodb/adodb.inc.php');
-	$db = <a href="#adonewconnection">ADONewConnection</a>($dbdriver); # eg 'mysql' or 'postgres'
-	$db->debug = true;
-	$db-><a href="#connect">Connect</a>($server, $user, $password, $database);
-	$rs = $db-><a href="#execute">Execute</a>('select * from some_small_table');
-	print &quot;&lt;pre&gt;&quot;;
-	print_r($rs-><a href="#getrows">GetRows</a>());
-	print &quot;&lt;/pre&gt;&quot;;
-?&gt;</pre>
-
- <h3>Minimum Install<a name=mininstall></a></h3>
-<p>For developers who want to release a minimal install of ADOdb, you will need:
-<ul>
-<li>adodb.inc.php
-<li>adodb-lib.inc.php
-<li>adodb-time.inc.php
-<li>adodb-csvlib.inc.php (if you use cached recordsets - CacheExecute(), etc)
-<li>adodb-error.inc.php and lang/adodb-$lang.inc.php (if you use MetaError())
-<li>drivers/adodb-$database.inc.php
-<li>license.txt (for legal reasons)
-</ul>
-
-<h3>Code Initialization Examples<a name="coding"></a></h3>
-<p>When running ADOdb, at least two files are loaded. First is adodb/adodb.inc.php, 
- which contains all functions used by all database classes. The code specific 
- to a particular database is in the adodb/driver/adodb-????.inc.php file.</p>
- <a name="adonewconnection">
-<p>For example, to connect to a mysql database:</p>
-<pre>
-include('/path/to/set/here/adodb.inc.php');
-$conn = &amp;ADONewConnection('mysql');
-</pre>
-<p>Whenever you need to connect to a database, you create a Connection object 
-  using the <b>ADONewConnection</b></a>($driver) function. 
-  <b>NewADOConnection</b>($driver) is an alternative name for the same function.</p>
-
-<p>At this point, you are not connected to the database. You will first need to decide
-whether to use <i>persistent</i> or <i>non-persistent</i> connections. The advantage of <i>persistent</i>
-connections is that they are faster, as the database connection is never closed (even 
-when you call Close()). <i>Non-persistent </i>connections take up much fewer resources though,
-reducing the risk of your database and your web-server becoming overloaded. 
-<p>For persistent connections,
-use $conn-&gt;<a href="reference.functions.pconnect.html">PConnect()</a>,
- or $conn-&gt;<a href="reference.functions.connect.html">Connect()</a> for non-persistent connections.
-Some database drivers also support <a href="reference.functions.nconnect.html">NConnect()</a>, which forces 
-the creation of a new connection. 
-<a name=connection_gotcha></a>
-<p><i>Connection Gotcha</i>:  If you create two connections, but both use the same userid and password,
-PHP will share the same connection. This can cause problems if the connections are meant to 
-different databases. The solution is to always use different userid's for different databases,
- or use NConnect().
-
-<h3>Examples of Connecting to Databases</h3>
-<h4>MySQL and Most Other Database Drivers</h4>
-<p>MySQL connections are very straightforward, and the parameters are identical 
-  to mysql_connect:</p>
-<pre>
-	$conn = &amp;ADONewConnection('mysql'); 
-	$conn-&gt;PConnect('localhost','userid','password','database');
- </pre>
-<p> Most other database drivers use a similar convention: Connect($server, $user, $password, $database). Exceptions are listed below.
-<h4>PostgreSQL</h4>
-<p>PostgreSQL accepts connections using: </p>
-<p>a. the standard connection string:</p>
-<pre>
-	$conn = &amp;ADONewConnection('postgres7'); 
-	$conn-&gt;PConnect('host=localhost port=5432 dbname=mary');</pre>
-<p> b. the classical 4 parameters:</p>
- <pre>
-	$conn-&gt;PConnect('localhost','userid','password','database');
- </pre>
-<h4>Interbase/Firebird</h4>
-You define the database in the $host parameter:
-<pre>
-	$conn = &ADONewConnection('ibase'); 
-	$conn->PConnect('localhost:c:\ibase\employee.gdb','sysdba','masterkey');
-</pre>
-<h4>SQLite</h4>
-Sqlite will create database if it does not exist.
-<pre>
-	$conn = &ADONewConnection('sqlite'); 
-	$conn->PConnect('c:\path\to\sqlite.db'); # sqlite will create if does not exist
-</pre>
-<h4>Oracle</h4>
-<p>With Oracle, you can connect in multiple ways.</p>
-<p>a. PHP and Oracle reside on the same machine, use default SID.</p>
-<pre>	$conn-&gt;Connect(false, 'scott', 'tiger');</pre>
-<p>b. TNS Name defined, eg. 'myTNS'</p>
-<pre>	$conn-&gt;PConnect(false, 'scott', 'tiger', 'myTNS');
-</pre>
-<p>or</p>
-<pre> 	$conn-&gt;PConnect('myTNS', 'scott', 'tiger');</pre>
-<p>c. Host Address and SID</p>
-<pre>	$conn-&gt;Connect('192.168.0.1', 'scott', 'tiger', 'SID');</pre>
-<p>d. Host Address and Service Name</p>
-<pre>	$conn-&gt;Connect('192.168.0.1', 'scott', 'tiger', 'servicename');</pre>
-<a name=dsnless></a>
-<h4>DSN-less ODBC (access and mssql examples)</h4>
-<p>ODBC DSN's can be created in the ODBC control panel, or you can use a DSN-less 
-  connection.To use DSN-less connections with ODBC you need PHP 4.3 or later. 
-</p>
-<p>For Microsoft Access:</a></p>
-<pre>
-	$db =& ADONewConnection('access');
-	$dsn = <strong>"Driver=&#123;Microsoft Access Driver (*.mdb)&#125;;Dbq=d:\\northwind.mdb;Uid=Admin;Pwd=;";</strong>
-	$db->Connect($dsn);
-</pre>
-For Microsoft SQL Server: 
-<pre>
-	$db =& ADONewConnection('odbc_mssql');
-	$dsn = <strong>"Driver=&#123;SQL Server&#125;;Server=localhost;Database=northwind;"</strong>;
-	$db->Connect($dsn,'userid','password');
-</pre>
-<b>DSN-less Connections with ADO</b><br>
-If you are using versions of PHP earlier than PHP 4.3.0, DSN-less connections 
-only work with Microsoft's ADO, which is Microsoft's COM based API. An example 
-using the ADOdb library and Microsoft's ADO: 
-<pre>
-&lt;?php
-	include('adodb.inc.php'); 
-	$db = &ADONewConnection("ado_mssql");
-	print "&lt;h1>Connecting DSN-less $db->databaseType...&lt;/h1>";
-		
-	<b>$myDSN="PROVIDER=MSDASQL;DRIVER=&#123;SQL Server&#125;;"
-		. "SERVER=flipper;DATABASE=ai;UID=sa;PWD=;"  ;</b>
-	$db->Connect($myDSN);
-	
-	$rs = $db->Execute("select * from table");
-	$arr = $rs->GetArray();
-	print_r($arr);

-<h2>High Speed ADOdb - tuning tips</h2>
-<p>ADOdb is a big class library, yet it <a href=http://phplens.com/lens/adodb/>consistently beats</a> all other PHP class 
-  libraries in performance. This is because it is designed in a layered fashion, 
-  like an onion, with the fastest functions in the innermost layer. Stick to the 
-  following functions for best performance:</p>
-<table width="40%" border="1" align="center">
-  <tr>
-    <td><div align="center"><b>Innermost Layer</b></div></td>
-  </tr>
-  <tr> 
-    <td><p align="center">Connect, PConnect, NConnect<br>
-        Execute, CacheExecute<br>
-        SelectLimit, SelectLimit<br>
-        MoveNext, Close <br>
-		qstr, Affected_Rows, Insert_ID</p></td>
-  </tr>
-</table>
-<p>The fastest way to access the fields is by accessing the array $recordset->fields 
-  directly. Also set the global variables <a href="#adodb_fetch_mode">$ADODB_FETCH_MODE</a> 
-  = ADODB_FETCH_NUM, and (for oci8, ibase/firebird and odbc) <a href="#adodb_countrecs">$ADODB_COUNTRECS</a> = false 
-  before you connect to your database. At the time of writing (Dec 2003).</p>
-<p>Consider using bind parameters if your database supports it, as it improves 
-  query plan reuse. Use ADOdb's performance tuning system to identify bottlenecks 
-  quickly. At the time of writing (Dec 2003), this means oci8 and odbc drivers.</p>
-<p>Lastly make sure you have a PHP accelerator cache installed such as APC, Turck 
-  MMCache, Zend Accelerator or ionCube.</p>
- <p>Informix tips: Disable scrollable cursors with $db->cursorType = 0.

-<h2>Hacking ADOdb Safely</h2>
-<p>You might want to modify ADOdb for your own purposes. Luckily you can
-still maintain backward compatibility by sub-classing ADOdb and using the $ADODB_NEWCONNECTION
-variable. $ADODB_NEWCONNECTION allows you to override the behaviour of ADONewConnection().
-ADOConnection() checks for this variable and will call
-the function-name stored in this variable if it is defined.
-<p>In the following example, new functionality for the connection object 
-is placed in the <i>hack_mysql</i> and <i>hack_postgres7</i> classes. The recordset class naming convention
-can be controlled using $rsPrefix. Here we set it to 'hack_rs_', which will make ADOdb use
-<i>hack_rs_mysql</i> and <i>hack_rs_postgres7</i> as the recordset classes.
-If you want to use the default ADOdb drivers return false.
-
-<pre>
-class hack_mysql extends adodb_mysql {
-var $rsPrefix = 'hack_rs_';
-  /* Your mods here */
-}
-
-class hack_rs_mysql extends ADORecordSet_mysql {
- /* Your mods here */
-}
-
-class hack_postgres7 extends adodb_postgres7 {
-var $rsPrefix = 'hack_rs_';
-  /* Your mods here */
-}
-
-class hack_rs_postgres7 extends ADORecordSet_postgres7 {
- /* Your mods here */
-}
-
-$ADODB_NEWCONNECTION = 'hack_factory';
-
-function& hack_factory($driver)
-{
-	if ($driver !== 'mysql' && $driver !== 'postgres7') return false;
-	
-	$driver = 'hack_'.$driver;
-	$obj = new $driver();
-	return $obj;
-}
-
-include_once('adodb.inc.php');
-
-</pre>
-<p>Don't forget to call the constructor of the parent class.
-<a name="php5">
-<h2>PHP5 Features</h2>

-		echo "r1=".$row[0]." r2=".$row[1]."&lt;br>";
-	}

-<p>
-<a name="php5exceptions">

-<p>The &quot;Tested&quot; column indicates how extensively the code has been tested 
-  and used. <br>
-  A = well tested and used by many people<br>
-  B = tested and usable, but some features might not be implemented<br>
-  C = user contributed or experimental driver. Might not fully support all of 
-  the latest features of ADOdb. </p>
-<p>The column &quot;RecordCount() usable&quot; indicates whether RecordCount() 
-  return the number of rows, or returns -1 when a SELECT statement is executed. 
-  If this column displays Y/N then the RecordCount() is emulated when the global 
-  variable $ADODB_COUNTRECS=true (this is the default). Note that for large recordsets, 
-  it might be better to disable RecordCount() emulation because substantial amounts 
-  of memory are required to cache the recordset for counting. Also there is a 
-  speed penalty of 40-50% if emulation is required. This is emulated in most databases 
-  except for PostgreSQL and MySQL. This variable is checked every time a query 
-  is executed, so you can selectively choose which recordsets to count.</p>

-<h3>Example 1: Select Statement<a name="ex1"></a></h3>
-<p>Task: Connect to the Access Northwind DSN, display the first 2 columns of each 
-  row.</p>
-<p>In this example, we create a ADOConnection object, which represents the connection 
-  to the database. The connection is initiated with <a href="#pconnect"><font face="Courier New, Courier, mono">PConnect</font></a>, 
-  which is a persistent connection. Whenever we want to query the database, we 
-  call the <font face="Courier New, Courier, mono">ADOConnection.<a href="#execute">Execute</a>()</font> 
-  function. This returns an ADORecordSet object which is actually a cursor that 
-  holds the current row in the array <font face="Courier New, Courier, mono">fields[]</font>. 
-  We use <font face="Courier New, Courier, mono"><a href="#movenext">MoveNext</a>()</font> 
-  to move from row to row.</p>
-<p>NB: A useful function that is not used in this example is <font face="Courier New, Courier, mono"><a href="#selectlimit">SelectLimit</a></font>, 
-  which allows us to limit the number of rows shown.

-</pre>
-<p>The $<font face="Courier New, Courier, mono">recordSet</font> returned stores 
-  the current row in the <font face="Courier New, Courier, mono">$recordSet-&gt;fields</font> 
-  array, indexed by column number (starting from zero). We use the <font face="Courier New, Courier, mono"><a href="#movenext">MoveNext</a>()</font> 
-  function to move to the next row. The <font face="Courier New, Courier, mono">EOF</font> 
-  property is set to true when end-of-file is reached. If an error occurs in Execute(), 
-  we return false instead of a recordset.</p>
-<p>The <code>$recordSet-&gt;fields[]</code> array is generated by the PHP database 
-  extension. Some database extensions only index by number and do not index the 
-  array by field name. To force indexing by name - that is associative arrays 
-  - use the SetFetchMode function. Each recordset saves and uses whatever fetch 
-  mode was set when the recordset was created in Execute() or SelectLimit(). 
-<pre>
-	$db->SetFetchMode(ADODB_FETCH_NUM);
-	$rs1 = $db->Execute('select * from table');
-	$db->SetFetchMode(ADODB_FETCH_ASSOC);
-	$rs2 = $db->Execute('select * from table');
-	print_r($rs1->fields); # shows <i>array([0]=>'v0',[1] =>'v1')</i>
-	print_r($rs2->fields); # shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
-</pre>
-<p> </p>
-<p>To get the number of rows in the select statement, you can use <font face="Courier New, Courier, mono">$recordSet-&gt;<a href="#recordcount">RecordCount</a>()</font>. 
-  Note that it can return -1 if the number of rows returned cannot be determined.</p>
-<h3>Example 2: Advanced Select with Field Objects<a name="ex2"></a></h3>

-</font>
-?>
-</pre>
-<p>In this example, we check the field type of the second column using <font face="Courier New, Courier, mono"><a href="#fetchfield">FetchField</a>().</font> 
-  This returns an object with at least 3 fields.</p>
-<ul>
-  <li><b>name</b>: name of column</li>
-  <li> <b>type</b>: native field type of column</li>
-  <li> <b>max_length</b>: maximum length of field. Some databases such as MySQL 
-    do not return the maximum length of the field correctly. In these cases max_length 
-    will be set to -1.</li>
-</ul>
-<p>We then use <font face="Courier New, Courier, mono"><a href="#metatype">MetaType</a>()</font> 
-  to translate the native type to a <i>generic</i> type. Currently the following 
-  <i>generic</i> types are defined:</p>
-<ul>
-  <li><b>C</b>: character fields that should be shown in a &lt;input type=&quot;text&quot;&gt; 
-    tag.</li>
-  <li><b>X</b>: TeXt, large text fields that should be shown in a &lt;textarea&gt;</li>
-  <li><b>B</b>: Blobs, or Binary Large Objects. Typically images. 
-  <li><b>D</b>: Date field</li>
-  <li><b>T</b>: Timestamp field</li>
-  <li><b>L</b>: Logical field (boolean or bit-field)</li>
-  <li><b>I</b>:&nbsp; Integer field</li>
-  <li><b>N</b>: Numeric field. Includes autoincrement, numeric, floating point, 
-    real and integer. </li>
-  <li><b>R</b>: Serial field. Includes serial, autoincrement integers. This works 
-    for selected databases. </li>
-</ul>
-<p>If the metatype is of type date or timestamp, then we print it using the user 
-  defined date format with <font face="Courier New, Courier, mono"><a href="#userdate">UserDate</a>(),</font> 
-  which converts the PHP SQL date string format to a user defined one. Another 
-  use for <font face="Courier New, Courier, mono"><a href="#metatype">MetaType</a>()</font> 
-  is data validation before doing an SQL insert or update.</p>
-<h3>Example 3: Inserting<a name="ex3"></a></h3>
-<p>Insert a row to the Orders table containing dates and strings that need to 
-  be quoted before they can be accepted by the database, eg: the single-quote 
-  in the word <i>John's</i>.</p>
-<pre>
-&lt;?
-<b>include</b>('adodb.inc.php');	   # load code common to ADOdb

-
-$<font color="#660000">conn</font>->PConnect('northwind');   # connect to MS-Access, northwind dsn
-$<font color="#660000">shipto</font> = <font color="#006600"><b>$conn-&gt;qstr</b></font>(&quot;<i>John's Old Shoppe</i>&quot;);
-
-$<font color="#660000">sql</font> = &quot;insert into orders (customerID,EmployeeID,OrderDate,ShipName) &quot;;
-$<font color="#660000">sql</font> .= &quot;values ('ANATR',2,&quot;.<b><font color="#006600">$conn-&gt;DBDate(</font>time()<font color="#006600">)</font></b><font color="#006600">.</font>&quot;,$<font color="#660000">shipto</font>)&quot;;
-
-<b>if</b> ($<font color="#660000">conn</font>->Execute($<font color="#660000">sql</font>) <font color="#336600"><b>=== false</b></font>) &#123;
-	<b>print</b> 'error inserting: '.<font color="#336600"><b>$conn-&gt;ErrorMsg()</b></font>.'&lt;BR&gt;';
-&#125;
-?>
-</pre>
-<p>In this example, we see the advanced date and quote handling facilities of 
-  ADOdb. The unix timestamp (which is a long integer) is appropriately formated 
-  for Access with <font face="Courier New, Courier, mono"><a href="#dbdate">DBDate</a>()</font>, 
-  and the right escape character is used for quoting the <i>John's Old Shoppe</i>, 
-  which is<b> </b><i>John'<b>'</b>s Old Shoppe</i> and not PHP's default <i>John<b>'</b>s 
-  Old Shoppe</i> with <font face="Courier New, Courier, mono"><a href="#qstr">qstr</a>()</font>. 
-</p>
-<p>Observe the error-handling of the Execute statement. False is returned by<font face="Courier New, Courier, mono"> 
-  <a href="#execute">Execute</a>() </font>if an error occured. The error message 
-  for the last error that occurred is displayed in <font face="Courier New, Courier, mono"><a href="#errormsg">ErrorMsg</a>()</font>. 
-  Note: <i>php_track_errors</i> might have to be enabled for error messages to 
-  be saved.</p>
-<h3> Example 4: Debugging<a name="ex4"></a></h3>
-<pre>&lt;?
-<b>include</b>('adodb.inc.php');	   # load code common to ADOdb
-$<font color="#663300">conn</font> = &amp;ADONewConnection('access');	# create a connection
-$<font color="#663300">conn</font>->PConnect('northwind');   # connect to MS-Access, northwind dsn
-<font color="#000000">$<font color="#663300">shipto</font> = <b>$conn-&gt;qstr</b>(&quot;John's Old Shoppe&quot;);
-$<font color="#663300">sql</font> = &quot;insert into orders (customerID,EmployeeID,OrderDate,ShipName) &quot;;
-$<font color="#663300">sql</font> .= &quot;values ('ANATR',2,&quot;.$<font color="#663300">conn</font>-&gt;FormatDate(time()).&quot;,$shipto)&quot;;
-<b><font color="#336600">$<font color="#663300">conn</font>-&gt;debug = true;</font></b>
-<b>if</b> ($<font color="#663300">conn</font>->Execute($sql) <b>=== false</b>) <b>print</b> 'error inserting';</font>
-?&gt;
-</pre>
-<p>In the above example, we have turned on debugging by setting <b>debug = true</b>. 
-  This will display the SQL statement before execution, and also show any error 
-  messages. There is no need to call <font face="Courier New, Courier, mono"><a href="#errormsg">ErrorMsg</a>()</font> 
-  in this case. For displaying the recordset, see the <font face="Courier New, Courier, mono"><a href="#exrs2html">rs2html</a>() 
-  </font>example.</p>
-<p>Also see the section on <a href=#errorhandling>Custom Error Handlers</a>.</p>
-<h3>Example 5: MySQL and Menus<a name="ex5"></a></h3>
-<p>Connect to MySQL database <i>agora</i>, and generate a &lt;select&gt; menu 
-  from an SQL statement where the &lt;option&gt; captions are in the 1st column, 
-  and the value to send back to the server is in the 2nd column.</p>
-<pre>&lt;?
-<b>include</b>('adodb.inc.php'); # load code common to ADOdb
-$<font color="#663300">conn</font> = &amp;ADONewConnection('mysql');  # create a connection
-$<font color="#663300">conn</font>->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
-<font color="#000000">$<font color="#663300">sql</font> = 'select CustomerName, CustomerID from customers';
-$<font color="#663300">rs</font> = $<font color="#663300">conn</font>->Execute($sql);
-<b>print</b> <b><font color="#336600">$<font color="#663300">rs</font>-&gt;GetMenu('GetCust','Mary Rosli');
-?&gt;</font></b></font></pre>
-<p>Here we define a menu named GetCust, with the menu option 'Mary Rosli' selected. 
-  See <a href="#getmenu"><font face="Courier New, Courier, mono">GetMenu</font></a><font face="Courier New, Courier, mono">()</font>. 
-  We also have functions that return the recordset as an array: <font face="Courier New, Courier, mono"><a href="#getarray">GetArray</a>()</font>, 
-  and as an associative array with the key being the first column: <a href="#getassoc1">GetAssoc</a>().</p>

-
-$conn1-&gt;Execute('insert ...');
-$conn2-&gt;Execute('update ...');
-?&gt;</pre>
-<p> 
-<h3>Example 7: Generating Update and Insert SQL<a name="ex7"></a></h3>
-ADOdb 1.31 and later supports two new recordset functions: GetUpdateSQL( ) and 
-GetInsertSQL( ). This allow you to perform a "SELECT * FROM table query WHERE...", 
-make a copy of the $rs->fields, modify the fields, and then generate the SQL to 
-update or insert into the table automatically. 
-<p> We show how the functions can be used when accessing a table with the following 
-  fields: (ID, FirstName, LastName, Created). 
-<p> Before these functions can be called, you need to initialize the recordset 
-  by performing a select on the table. Idea and code by Jonathan Younger jyounger#unilab.com. 
-<p> 
-<pre>&lt;?

-<h3>Example 8: Implementing Scrolling with Next and Previous<a name="ex8"></a></h3>

-
-$sql = "select * from adoxyz ";
-
-$pager = new ADODB_Pager($db,$sql);
-$pager->Render($rows_per_page=5);</pre>
-<p>This will create a basic record pager that looks like this: <a name="scr"></a>

-<p>The number of rows to display at one time is controled by the Render($rows) 
-  method. If you do not pass any value to Render(), ADODB_Pager will default to 
-  10 records per page. 
-<p>You can control the column titles by modifying your SQL (supported by most 
-  databases): 
-<pre>$sql = 'select id as &quot;ID&quot;, firstname as &quot;First Name&quot;, 
-		  lastname as &quot;Last Name&quot;, created as &quot;Date Created&quot; <br>		from adoxyz';</pre>
-<p>The above code can be found in the <i>adodb/tests/testpaging.php</i> example 
-  included with this release, and the class ADODB_Pager in <i>adodb/adodb-pager.inc.php</i>. 
-  The ADODB_Pager code can be adapted by a programmer so that the text links can 
-  be replaced by images, and the dull white background be replaced with more interesting 
-  colors. 
-<p>You can also allow display of html by setting $pager->htmlSpecialChars = false.

-</pre>
-<p> Carriage-returns or newlines are converted to spaces. Field names are returned 
-  in the first line of text. Strings containing the delimiter character are quoted 
-  with double-quotes. Double-quotes are double-quoted again. This conforms to 
-  Excel import and export guide-lines. 
-<p>All the above functions take as an optional last parameter, $addtitles which 
-  defaults to <i>true</i>. When set to <i>false</i> field names in the first line

-<h3>Example 10: Recordset Filters<a name="ex10"></a></h3>
-<p>Sometimes we want to pre-process all rows in a recordset before we use it. 
-  For example, we want to ucwords all text in recordset. 
-<pre>
-include_once('adodb/rsfilter.inc.php');
-include_once('adodb/adodb.inc.php');
-
-// ucwords() every element in the recordset
-function do_ucwords(&$arr,$rs)
-&#123;
-	foreach($arr as $k => $v) &#123;
-		$arr[$k] = ucwords($v);
-	&#125;
-&#125;
-
-$db = NewADOConnection('mysql');
-$db->PConnect('server','user','pwd','db');
-
-$rs = $db->Execute('select ... from table');
-$rs = <b>RSFilter</b>($rs,'do_ucwords');
-</pre>
-<p>The <i>RSFilter</i> function takes 2 parameters, the recordset, and the name 
-  of the <i>filter</i> function. It returns the processed recordset scrolled to 
-  the first record. The <i>filter</i> function takes two parameters, the current 
-  row as an array, and the recordset object. For future compatibility, you should 
-  not use the original recordset object. </p>
-<h3>Example 11:<a name="ex11"></a> Smart Transactions</h3>
-The old way of doing transactions required you to use 
-<pre>
-$conn-><b>BeginTrans</b>();
-$ok = $conn->Execute($sql);
-if ($ok) $ok = $conn->Execute($sql2);
-if (!$ok) $conn-><b>RollbackTrans</b>();
-else $conn-><b>CommitTrans</b>();
-</pre>
-This is very complicated for large projects because you have to track the error 
-status. Smart Transactions is much simpler. You start a smart transaction by calling 
-StartTrans(): 
-<pre>
-$conn-><b>StartTrans</b>();
-$conn->Execute($sql);
-$conn->Execute($Sql2);
-$conn-><b>CompleteTrans</b>();
-</pre>
-CompleteTrans() detects when an SQL error occurs, and will Rollback/Commit as 
-appropriate. To specificly force a rollback even if no error occured, use FailTrans(). 
-Note that the rollback is done in CompleteTrans(), and not in FailTrans(). 
-<pre>
-$conn-><b>StartTrans</b>();
-$conn->Execute($sql);
-if (!CheckRecords()) $conn-><strong>FailTrans</strong>();
-$conn->Execute($Sql2);
-$conn-><b>CompleteTrans</b>();
-</pre>
-<p>You can also check if a transaction has failed, using HasFailedTrans(), which 
-  returns true if FailTrans() was called, or there was an error in the SQL execution. 
-  Make sure you call HasFailedTrans() before you call CompleteTrans(), as it is 
-  only works between StartTrans/CompleteTrans.
-<p>Lastly, StartTrans/CompleteTrans is nestable, and only the outermost block 
-  is executed. In contrast, BeginTrans/CommitTrans/RollbackTrans is NOT nestable. 
-<pre>
-$conn-><strong>StartTrans</strong>();
-$conn->Execute($sql);
-  $conn-><strong>StartTrans</strong>();    <font color="#006600"># ignored</font>
-  if (!CheckRecords()) $conn->FailTrans();
-  $conn-><strong>CompleteTrans</strong>(); <font color="#006600"># ignored</font>
-$conn->Execute($Sql2);
-$conn-><strong>CompleteTrans</strong>();
-</pre>

-<h2><a name="errorhandling"></a>Using Custom Error Handlers and PEAR_Error</h2>
-Apart from the old $con->debug = true; way of debugging, ADOdb 1.50 onwards provides 
-another way of handling errors using ADOdb's custom error handlers. 
-<p> ADOdb provides two custom handlers which you can modify for your needs. The 
-  first one is in the <b>adodb-errorhandler.inc.php</b> file. This makes use of 
-  the standard PHP functions <a href=http://php.net/error_reporting>error_reporting</a> 
-  to control what error messages types to display, and <a href=http://php.net/trigger_error>trigger_error</a> 
-  which invokes the default PHP error handler. 
-<p> Including the above file will cause <i>trigger_error($errorstring,E_USER_ERROR)</i> 
-  to be called when<br>
-  (a) Connect() or PConnect() fails, or <br>
-  (b) a function that executes SQL statements such as Execute() or SelectLimit() 
-  has an error.<br>
-  (c) GenID() appears to go into an infinite loop. 
-<p> The $errorstring is generated by ADOdb and will contain useful debugging information 
-  similar to the error.log data generated below. This file adodb-errorhandler.inc.php 
-  should be included before you create any ADOConnection objects. 
-<p> If you define error_reporting(0), no errors will be passed to the error handler. 
-  If you set error_reporting(E_ALL), all errors will be passed to the error handler. 
-  You still need to use <b>ini_set("display_errors", "0" or "1")</b> to control 
-  the display of errors. 
-<pre>
-&lt;?php
-<b>error_reporting(E_ALL); # pass any error messages triggered to error handler
-include('adodb-errorhandler.inc.php');</b>
-include('adodb.inc.php');
-include('tohtml.inc.php');
-$c = NewADOConnection('mysql');
-$c->PConnect('localhost','root','','northwind');
-$rs=$c->Execute('select * from productsz'); #invalid table productsz');
-if ($rs) rs2html($rs);
-?>
-</pre>
-<p> If you want to log the error message, you can do so by defining the following 
-  optional constants ADODB_ERROR_LOG_TYPE and ADODB_ERROR_LOG_DEST. ADODB_ERROR_LOG_TYPE 
-  is the error log message type (see <a href=http://php.net/error_log>error_log</a> 
-  in the PHP manual). In this case we set it to 3, which means log to the file 
-  defined by the constant ADODB_ERROR_LOG_DEST. 
-<pre>
-&lt;?php
-<b>error_reporting(E_ALL); # report all errors
-ini_set("display_errors", "0"); # but do not echo the errors
-define('ADODB_ERROR_LOG_TYPE',3);
-define('ADODB_ERROR_LOG_DEST','C:/errors.log');
-include('adodb-errorhandler.inc.php');</b>
-include('adodb.inc.php');
-include('tohtml.inc.php');
-
-$c = NewADOConnection('mysql');
-$c->PConnect('localhost','root','','northwind');
-$rs=$c->Execute('select * from productsz'); ## invalid table productsz
-if ($rs) rs2html($rs);
-?>
-</pre>
-The following message will be logged in the error.log file: 
-<pre>
-(2001-10-28 14:20:38) mysql error: [1146: Table 'northwind.productsz' doesn't exist] in
- EXECUTE("select * from productsz")
-</pre>
-The second error handler is <b>adodb-errorpear.inc.php</b>. This will create a 
-PEAR_Error derived object whenever an error occurs. The last PEAR_Error object 
-created can be retrieved using ADODB_Pear_Error(). 
-<pre>
-&lt;?php
-<b>include('adodb-errorpear.inc.php');</b>
-include('adodb.inc.php');
-include('tohtml.inc.php');
-$c = NewADOConnection('mysql');
-$c->PConnect('localhost','root','','northwind');
-$rs=$c->Execute('select * from productsz'); #invalid table productsz');
-if ($rs) rs2html($rs);
-else &#123;
-	<b>$e = ADODB_Pear_Error();
-	echo '&lt;p>',$e->message,'&lt;/p>';</b>
-&#125;
-?>
-</pre>
-<p> You can use a PEAR_Error derived class by defining the constant ADODB_PEAR_ERROR_CLASS 
-  before the adodb-errorpear.inc.php file is included. For easy debugging, you 
-  can set the default error handler in the beginning of the PHP script to PEAR_ERROR_DIE, 
-  which will cause an error message to be printed, then halt script execution: 
-<pre>
-include('PEAR.php');
-PEAR::setErrorHandling('PEAR_ERROR_DIE');
-</pre>
-<p> Note that we do not explicitly return a PEAR_Error object to you when an error 
-  occurs. We return false instead. You have to call ADODB_Pear_Error() to get 
-  the last error or use the PEAR_ERROR_DIE technique. 
-<h4>Error Messages</h4>
-<p>Error messages are outputted using the static method ADOConnnection::outp($msg,$newline=true). 
-  By default, it sends the messages to the client. You can override this to perform 
-  error-logging. 
-<h2><a name="dsn"></a> Data Source Names</h2>
-<p>We now support connecting using PEAR style DSN's. A DSN is a connection string 
-  of the form:</p>
-<p>$dsn = <i>&quot;$driver://$username:$password@$hostname/$databasename&quot;</i>;</p>
-<p>You pass the DSN to the static class function DB::Connect. An example:</p>
-<pre>   include_once('../adodb/adodb-pear.inc.php');
-   $username = 'root';
-   $password = '';
-   $hostname = 'localhost';
-   $databasename = 'xphplens';
-   $driver = 'mysql';
-   $dsn = &quot;$driver://$username:$password@$hostname/$databasename&quot;;</pre>
-<pre>   $db = DB::Connect($dsn);<br>   $rs = $db-&gt;Execute('select firstname,lastname from adoxyz');
-   $cnt = 0;
-   while ($arr = $rs-&gt;FetchRow()) {
-		print_r($arr); print &quot;&lt;br&gt;&quot;;
-   }</pre>
-<p>This requires PEAR to be installed and in the default include path in php.ini.</p>
-<h2><a name="caching"></a>Caching of Recordsets</h2>
-<p>ADOdb now supports caching of recordsets using the CacheExecute( ), CachePageExecute( 
-  ) and CacheSelectLimit( ) functions. There are similar to the non-cache functions, 
-  except that they take a new first parameter, $secs2cache. 
-<p> An example: 
-<pre>
-<b>include</b>('adodb.inc.php'); # load code common to ADOdb
-$ADODB_CACHE_DIR = '/usr/ADODB_cache';
-$<font color="#663300">conn</font> = &amp;ADONewConnection('mysql');  # create a connection
-$<font color="#663300">conn</font>->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
-<font color="#000000">$<font color="#663300">sql</font> = 'select CustomerName, CustomerID from customers';
-$<font color="#663300">rs</font> = $<font color="#663300">conn</font>->CacheExecute(15,$sql);</font></pre>
-<p><font color="#000000"> The first parameter is the number of seconds to cache 
-  the query. Subsequent calls to that query will used the cached version stored 
-  in $ADODB_CACHE_DIR. To force a query to execute and flush the cache, call CacheExecute() 
-  with the first parameter set to zero. Alternatively, use the CacheFlush($sql) 
-  call. </font></p>
-<p><font color="#000000">For the sake of security, we recommend you set <i>register_globals=off</i> 
-  in php.ini if you are using $ADODB_CACHE_DIR.</font></p>
-<p>In ADOdb 1.80 onwards, the secs2cache parameter is optional in CacheSelectLimit() 
-  and CacheExecute(). If you leave it out, it will use the $connection->cacheSecs 
-  parameter, which defaults to 60 minutes. 
-<pre>
-	$conn->Connect(...);
-	$conn->cacheSecs = 3600*24; # cache 24 hours
-	$rs = $conn->CacheExecute('select * from table');
-</pre>
-<p>Please note that magic_quotes_runtime should be turned off. <a href=http://phplens.com/lens/lensforum/msgs.php?LeNs#LensBM_forummsg>More

-<h2><a name="pivot"></a>Pivot Tables</h2>
-</font> <p><font color="#000000">Since ADOdb 2.30, we support the generation of 
-SQL to create pivot tables, also known as cross-tabulations. For further explanation 
-read this DevShed <a href=http://www.devshed.com/Server_Side/MySQL/MySQLWiz/>Cross-Tabulation 
-tutorial. We assume that your database supports the SQL case-when expression. </font></p> 
-<font color="#000000"> 
-<p>In this example, we will use the Northwind database from Microsoft. In the 
-  database, we have a products table, and we want to analyze this table by <i>suppliers 
-  versus product categories</i>. We will place the suppliers on each row, and 
-  pivot on categories. So from the table on the left, we generate the pivot-table

-	the global variable $ADODB_COUNTRECS is set to true, which is the default. 
-	We emulate this by buffering the records, which can take up large amounts 
-	of memory for big recordsets. Set this variable to false for the best performance. 
-	This variable is checked every time a query is executed, so you can selectively 
-	choose which recordsets to count.</p>
-<h3><font color="#000000"><a name="adodb_cache_dir"></a>$ADODB_CACHE_DIR</font></h3>
-<font color="#000000"> 
-<p>If you are using recordset caching, this is the directory to save your recordsets

-  feature for security reasons.</p>
-<p>If you are using Unix and apache, you might need to set your cache directory

-drivers. Added in ADOdb 4.01.
-<h3><font color="#000000"><a name="adodb_lang"></a></font>$ADODB_LANG</h3>

-<h3><a name="adodb_fetch_mode"></a>$ADODB_FETCH_MODE</h3>
-<p>This is a global variable that determines how arrays are retrieved by recordsets. 
-  The recordset saves this value on creation (eg. in Execute( ) or SelectLimit( 
-  )), and any subsequent changes to $ADODB_FETCH_MODE have no affect on existing 
-  recordsets, only on recordsets created in the future.</p>
-<p>The following constants are defined:</p>
-</font> 
-<p><font color="#000000">define('ADODB_FETCH_DEFAULT',0);<br>
-  define('ADODB_FETCH_NUM',1);<br>
-  define('ADODB_FETCH_ASSOC',2);<br>

-	print_r($rs2->fields); # shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
-</pre>
-<p> As you can see in the above example, both recordsets store and use different 
-	fetch modes based on the $ADODB_FETCH_MODE setting when the recordset was 
-	created by Execute().</p>
-<p>If no fetch mode is predefined, the fetch mode defaults to ADODB_FETCH_DEFAULT. 
-	The behaviour of this default mode varies from driver to driver, so do not

-	or ADODB_FETCH_ASSOC. Many drivers do not support ADODB_FETCH_BOTH.</p>
-<p><strong>SetFetchMode Function</strong></p>
-<p>Some programmers prefer to use a more object-oriented solution, where the fetch 
-	mode is set by a object function, <a href="#setfetchmode">SetFetchMode</a>. 
-	Once this function is called for a connection object, that connection object 
-	will ignore the global variable $ADODB_FETCH_MODE and will use the internal 
-	fetchMode property exclusively.</p>

-<p><strong><a name="adodb_assoc_case"></a>ADODB_ASSOC_CASE</strong></p>
-<p>You can control the associative fetch case for certain drivers which behave 
-	differently. For the sybase, oci8po, mssql, odbc and ibase drivers and all 
-	drivers derived from them, ADODB_ASSOC_CASE will by default generate recordsets 
-	where the field name keys are lower-cased. Use the constant ADODB_ASSOC_CASE 
-	to change the case of the keys. There are 3 possible values:</p>
-<p>0 = assoc lowercase field names. $rs-&gt;fields['orderid']<br>
-	1 = assoc uppercase field names. $rs-&gt;fields['ORDERID']<br>
-	2 = use native-case field names. $rs-&gt;fields['OrderID'] -- this is the

-	and has a set of utility functions for standardising the format of SQL statements 
-	for issues such as concatenation and date formats.</p>
-<h3>ADOConnection Fields</h3>
-<p><b>databaseType</b>: Name of the database system we are connecting to. Eg. 
-	<b>odbc</b> or <b>mssql</b> or <b>mysql</b>.</p>
-<p><b>dataProvider</b>: The underlying mechanism used to connect to the database. 
-	Normally set to <b>native</b>, unless using <b>odbc</b> or <b>ado</b>.</p>
-<p><b>host: </b>Name of server or data source name (DSN) to connect to.</p>
-<p><b>database</b>: Name of the database or to connect to. If ado is used, it 
-	will hold the ado data provider.</p>
-<p><b>user</b>: Login id to connect to database. Password is not saved for security 
-	reasons.</p>
-<p><b>raiseErrorFn</b>: Allows you to define an error handling function. See adodb-errorhandler.inc.php 
-	for an example.</p>
-<p><b>debug</b>: Set to <i>true</i> to make debug statements to appear.</p>
-<p><b>concat_operator</b>: Set to '+' or '||' normally. The operator used to concatenate 
-	strings in SQL. Used by the <b><a href="#concat">Concat</a></b> function.</p>
-<p><b>fmtDate</b>: The format used by the <b><a href="#dbdate">DBDate</a></b> 
-	function to send dates to the database. is '#Y-m-d#' for Microsoft Access, 
-	and ''Y-m-d'' for MySQL.</p>
-<p><b>fmtTimeStamp: </b>The format used by the <b><a href="#dbtimestamp">DBTimeStamp</a></b> 
-	function to send timestamps to the database. </p>
-<p><b>true</b>: The value used to represent true.Eg. '.T.'. for Foxpro, '1' for 
-	Microsoft SQL.</p>
-<p><b>false: </b> The value used to represent false. Eg. '.F.'. for Foxpro, '0' 
-	for Microsoft SQL.</p>
-<p><b>replaceQuote</b>: The string used to escape quotes. Eg. double single-quotes 
-	for Microsoft SQL, and backslash-quote for MySQL. Used by <a href="#qstr">qstr</a>.</p>
-<p><b>autoCommit</b>: indicates whether automatic commit is enabled. Default is 
-	true.</p>
-<p><b>charSet</b>: set the default charset to use. Currently only interbase supports 
-	this.</p>
-<p><b>dialect</b>: set the default sql dialect to use. Currently only interbase 
-	supports this.</p>
-<p><b>metaTablesSQL</b>: SQL statement to return a list of available tables. Eg. 
-	<i>SHOW TABLES</i> in MySQL.</p>

-	) if this is set to true. Default is false.</p>
-<hr>
-<h3>ADOConnection Main Functions</h3>
-<p><b>ADOConnection( )</b></p>
-<p>Constructor function. Do not call this directly. Use ADONewConnection( ) instead.</p>
-<p><b>Connect<a name="connect"></a>($host,[$user],[$password],[$database])</b></p>
-<p>Non-persistent connect to data source or server $<b>host</b>, using userid 
-	$<b>user </b>and password $<b>password</b>. If the server supports multiple 
-	databases, connect to database $<b>database</b>. </p>
-<p>Returns true/false depending on connection.</p>
-<p>ADO Note: If you are using a Microsoft ADO and not OLEDB, you can set the $database 
-	parameter to the OLEDB data provider you are using.</p>
-<p>PostgreSQL: An alternative way of connecting to the database is to pass the 
-	standard PostgreSQL connection string in the first parameter $host, and the 
-	other parameters will be ignored.</p>
-<p>For Oracle and Oci8, there are two ways to connect. First is to use the TNS 
-	name defined in your local tnsnames.ora (or ONAMES or HOSTNAMES). Place the 
-	name in the $database field, and set the $host field to false. Alternatively, 
-	set $host to the server, and $database to the database SID, this bypassed 
-	tnsnames.ora. 
-<p>Examples: 
-<pre> # $oraname in tnsnames.ora/ONAMES/HOSTNAMES
- $conn->Connect(false, 'scott', 'tiger', $oraname); 
- $conn->Connect('server:1521', 'scott', 'tiger', 'ServiceName'); # bypass tnsnames.ora</pre>
-<p>There are many examples of connecting to a database at <a href="http://php.weblogs.com/adodb">php.weblogs.com/ADOdb</a>, 
-	and in the testdatabases.inc.php file included in the release.</p>
-<p><b>PConnect<a name="pconnect"></a>($host,[$user],[$password],[$database])</b></p>
-<p>Persistent connect to data source or server $<b>host</b>, using userid $<b>user</b> 
-	and password $<b>password</b>. If the server supports multiple databases, 
-	connect to database $<b>database</b>.</p>
-<p>We now perform a rollback on persistent connection for selected databases since 
-	2.21, as advised in the PHP manual. See change log or source code for which 
-	databases are affected. 
-<p>Returns true/false depending on connection. See Connect( ) above for more info.</p>
-<p>Since ADOdb 2.21, we also support autoRollback. If you set:</p>
-</font> 
-<pre> $conn = &amp;NewADOConnection('mysql');
- $conn-&gt;autoRollback = true; # default is false
- $conn-&gt;PConnect(...); # rollback here</pre>
-<p> Then when doing a persistent connection with PConnect( ), ADOdb will 
-  perform a rollback first. This is because it is documented that PHP is 
-  not guaranteed to rollback existing failed transactions when 
-  persistent connections are used. This is implemented in Oracle, 
-  MySQL, PgSQL, MSSQL, ODBC currently. 
-<p>Since ADOdb 3.11, you can force non-persistent 
-connections even if PConnect is called by defining the constant 
-ADODB_NEVER_PERSIST  before you call PConnect.
-<p><b>NConnect<a name="nconnect"></a>($host,[$user],[$password],[$database])</b></p>
-<p>Always force a new connection. In contrast, PHP sometimes reuses connections 
-	when you use Connect() or PConnect(). Currently works only on mysql (PHP 4.3.0 
-	or later), postgresql and oci8-derived drivers. For other drivers, NConnect() works like 
-	Connect(). 
-<font color="#000000"> 
-<p><b>Execute<a name="execute"></a>($sql,$inputarr=false)</b></p>
-<p>Execute SQL statement $<b>sql</b> and return derived class of ADORecordSet 
-	if successful. Note that a record set is always returned on success, even 
-	if we are executing an insert or update statement. You can also pass in $sql a statement prepared 
-	in <a href=#prepare>Prepare()</a>.</p>
-<p>Returns derived class of ADORecordSet. Eg. if connecting via mysql, then ADORecordSet_mysql 
-	would be returned. False is returned if there was an error in executing the 
-	sql.</p>
-<p>The $inputarr parameter can be used for binding variables to parameters. Below 
-	is an Oracle example:</p>
-<pre>
- $conn->Execute("SELECT * FROM TABLE WHERE COND=:val", array('val'=> $val));
- </pre>
-<p>Another example, using ODBC,which uses the ? convention:</p>
-<pre>
-  $conn->Execute("SELECT * FROM TABLE WHERE COND=?", array($val));
-</pre>
-<a name="binding"></a>
-<i>Binding variables</i><p>
-Variable binding speeds the compilation and caching of SQL statements, leading 
-to higher performance. Currently Oracle, Interbase and ODBC supports variable binding. 
-Interbase/ODBC style ? binding is emulated in databases that do not support binding. 
-Note that you do not have to quote strings if you use binding.
-<p> Variable binding in the odbc, interbase and oci8po drivers. 
-<pre>
-$rs = $db->Execute('select * from table where val=?', array('10'));
-</pre>
-Variable binding in the oci8 driver: 
-<pre>
-$rs = $db->Execute('select name from table where val=:key', 
-  array('key' => 10));
-</pre>
-<a name="bulkbind"></a>
-<i>Bulk binding</i>
-<p>Since ADOdb 3.80, we support bulk binding in Execute(), in which you pass in a 2-dimensional array to
-be bound to an INSERT/UPDATE or DELETE statement.
-<pre>
-$arr = array(
-	array('Ahmad',32),
-	array('Zulkifli', 24),
-	array('Rosnah', 21)
-	);
-$ok = $db->Execute('insert into table (name,age) values (?,?)',$arr);
-</pre>
-<p>This provides very high performance as the SQL statement is prepared first. 
-The prepared statement is executed repeatedly for each array row until all rows are completed, 
-or until the first error. Very useful for importing data.
-
-<p><b>CacheExecute<a name="cacheexecute"></a>([$secs2cache,]$sql,$inputarr=false)</b></p>
-<p>Similar to Execute, except that the recordset is cached for $secs2cache seconds 
-	in the $ADODB_CACHE_DIR directory, and $inputarr only accepts 1-dimensional arrays. 
-	If CacheExecute() is called again with the same $sql, $inputarr, 
-	and also the same database, same userid, and the cached recordset 
-	has not expired, the cached recordset is returned. 
-<pre>
-  include('adodb.inc.php'); 
-  include('tohtml.inc.php');
-  $ADODB_<b>CACHE_DIR</b> = '/usr/local/ADOdbcache';
-  $conn = &ADONewConnection('mysql'); 
-  $conn->PConnect('localhost','userid','password','database');
-  $rs = $conn-><b>CacheExecute</b>(15, 'select * from table'); # cache 15 secs
-  rs2html($rs); /* recordset to html table */  
-</pre>
-<p> Alternatively, since ADOdb 1.80, the $secs2cache parameter is optional:</p>
-<pre>	$conn-&gt;Connect(...);
-   	$conn-&gt;cacheSecs = 3600*24; // cache 24 hours
-	$rs = $conn-&gt;CacheExecute('select * from table');
-</pre>
-If $secs2cache is omitted, we use the value 
-in $connection-&gt;cacheSecs (default is 3600 seconds, or 1 hour). Use CacheExecute() 
-only with SELECT statements. 
-<p>Performance note: I have done some benchmarks and found that they vary so greatly 
-	that it's better to talk about when caching is of benefit. When your database 
-	server is <i>much slower </i>than your Web server or the database is <i>very 
-	overloaded </i>then ADOdb's caching is good because it reduces the load on 
-	your database server. If your database server is lightly loaded or much faster 
-	than your Web server, then caching could actually reduce performance. </p>
-<p><b>ExecuteCursor<a name="executecursor"></a>($sql,$cursorName='rs',$parameters=false)</b></p>
-<p>Execute an Oracle stored procedure, and returns an Oracle REF cursor variable as 
-	a regular ADOdb recordset. Does not work with any other database except oci8. 
-	Thanks to Robert Tuttle for the design.
-<pre>
-    $db = ADONewConnection("oci8"); 
-    $db->Connect("foo.com:1521", "uid", "pwd", "FOO"); 
-    $rs = $db->ExecuteCursor("begin :cursorvar := getdata(:param1); end;", 
-					'cursorvar',
-					array('param1'=>10)); 
-    # $rs is now just like any other ADOdb recordset object<br>    rs2html($rs);</pre>
-<p>ExecuteCursor() is a helper function that does the following internally: 
-<pre>
-	$stmt = $db->Prepare("BEGIN :RS := SP_FOO(); END;", true); 
-	$db->Parameter($stmt, $cur, 'RS', false, -1, OCI_B_CURSOR);
-	$rs = $db->Execute($stmt);</pre>
-<p><b>SelectLimit<a name="selectlimit"></a>($sql,$numrows=-1,$offset=-1,$inputarr=false)</b></p>
-<p>Returns a recordset if successful. Returns false otherwise. Performs a select 
-	statement, simulating PostgreSQL's SELECT statement, LIMIT $numrows OFFSET 
-	$offset clause.</p>
-<p>In PostgreSQL, SELECT * FROM TABLE LIMIT 3 will return the first 3 records 
-	only. The equivalent is <code>$connection->SelectLimit('SELECT * FROM TABLE',3)</code>. 
-	This functionality is simulated for databases that do not possess this feature.</p>
-<p>And SELECT * FROM TABLE LIMIT 3 OFFSET 2 will return records 3, 4 and 5 (eg. 
-	after record 2, return 3 rows). The equivalent in ADOdb is <code>$connection->SelectLimit('SELECT 
-	* FROM TABLE',3,2)</code>.</p>
-<p>Note that this is the <i>opposite</i> of MySQL's LIMIT clause. You can also 
-	set <code>$connection->SelectLimit('SELECT * FROM TABLE',-1,10)</code> to 
-	get rows 11 to the last row.</p>
-<p>The last parameter $inputarr is for databases that support variable binding 
-	such as Oracle oci8. This substantially reduces SQL compilation overhead. 
-	Below is an Oracle example:</p>
-<pre>
- $conn->SelectLimit("SELECT * FROM TABLE WHERE COND=:val", 100,-1,array('val'=> $val));
- </pre>
-<p>The oci8po driver (oracle portable driver) uses the more standard bind variable 
-	of ?: 
-<pre>
- $conn->SelectLimit("SELECT * FROM TABLE WHERE COND=?", 100,-1,array('val'=> $val));
-</pre>
-<p> 
-<p>Ron Wilson reports that SelectLimit does not work with UNIONs. 
-<p><b>CacheSelectLimit<a name="cacheselectlimit"></a>([$secs2cache,] $sql, $numrows=-1,$offset=-1,$inputarr=false)</b></p>
-<p>Similar to SelectLimit, except that the recordset returned is cached for $secs2cache 
-	seconds in the $ADODB_CACHE_DIR directory. </p>
-<p>Since 1.80, $secs2cache has been optional, and you can define the caching time 
-	in $connection-&gt;cacheSecs.</p>
-</font> 
-<pre><font color="#000000">	$conn-&gt;Connect(...);
-   $conn-&gt;cacheSecs = 3600*24; // cache 24 hours
-	$rs = $conn-&gt;CacheSelectLimit('select * from table',10);</font></pre>
-<font color="#000000"> 
-<p><b>CacheFlush<a name="cacheflush"></a>($sql=false,$inputarr=false)</b></p>
-<p>Flush (delete) any cached recordsets for the SQL statement $sql in $ADODB_CACHE_DIR. 
-<p>If no parameter is passed in, then all adodb_*.cache files are deleted. 
-<p> If you want to flush all cached recordsets manually, execute the following 
-	PHP code (works only under Unix): <br>
-	<code> &nbsp; system(&quot;rm -f `find &quot;.$ADODB_CACHE_DIR.&quot; -name 
-	adodb_*.cache`&quot;);</code></p>
-<p>For general cleanup of all expired files, you should use <a href="http://www.superscripts.com/tutorial/crontab.html">crontab</a> 
-	on Unix, or at.exe on Windows, and a shell script similar to the following:<font face="Courier New, Courier, mono"><br>
-	#------------------------------------------------------ <br>
-	# This particular example deletes files in the TMPPATH <br>
-	# directory with the string &quot;.cache&quot; in their name that <br>
-	# are more than 7 days old. <br>
-	#------------------------------------------------------ <br>
-	AGED=7 <br>
-	find ${TMPPATH} -mtime +$AGED | grep &quot;\.cache&quot; | xargs rm -f <br>
-	</font> </p>
-<p><b>MetaError<a name="metaerror"></a>($errno=false)</b></p>
-<p>Returns a virtualized error number, based on PEAR DB's error number system. You might
-need to include adodb-error.inc.php before you call this function. The parameter $errno
-is the native error number you want to convert. If you do not pass any parameter, MetaError
-will call ErrorNo() for you and convert it. If the error number cannot be virtualized, MetaError 
-will return -1 (DB_ERROR).</p>
-
-<p><b>MetaErrorMsg<a name="metaerrormsg"></a>($errno)</b></p>
-<p>Pass the error number returned by MetaError() for the equivalent textual error message.</p>
-<p><b>ErrorMsg<a name="errormsg"></a>()</b></p>
-<p>Returns the last status or error message. The error message is reset after every 
-call to Execute(). 
-<p>
-This can return a string even if 
-	no error occurs. In general you do not need to call this function unless an 
-	ADOdb function returns false on an error. </p>
-<p>Note: If <b>debug</b> is enabled, the SQL error message is always displayed 
-	when the <b>Execute</b> function is called.</p>
-<p><b>ErrorNo<a name="errorno"></a>()</b></p>
-<p>Returns the last error number. The error number is reset after every call to Execute(). 
-If 0 is returned, no error occurred.
-<p>
-Note that old versions of PHP (pre 4.0.6) do 
-	not support error number for ODBC. In general you do not need to call this 
-	function unless an ADOdb function returns false on an error.</p>
-</font>
-<p><font color="#000000"><b>SetFetchMode<a name="setfetchmode"></a>($mode)</b></font></p>
-<p><font color="#000000">Sets the current fetch mode for the connection and stores 
-	it in $db-&gt;fetchMode. Legal modes are ADODB_FETCH_ASSOC and ADODB_FETCH_NUM. 
-	For more info, see <a href="#adodb_fetch_mode">$ADODB_FETCH_MODE</a>.</font></p>
-<p><font color="#000000">Returns the previous fetch mode, which could be false 
-	if SetFetchMode( ) has not been called before.</font></p>
-<font color="#000000"> 
-<p><b>CreateSequence<a name="createseq"></a>($seqName = 'adodbseq',$startID=1)</b></p>
-<p>Create a sequence. The next time GenID( ) is called, the value returned will 
-	be $startID. Added in 2.60. 
-<p><b>DropSequenceD<a name="dropseq"></a>($seqName = 'adodbseq')</b></p>
-<p>Delete a sequence. Added in 2.60. 
-<p><b>GenID<a name="genid"></a>($seqName = 'adodbseq',$startID=1)</b></p>
-<p>Generate a sequence number . Works for interbase, 
-	mysql, postgresql, oci8, oci8po, mssql, ODBC based (access,vfp,db2,etc) drivers 
-	currently. Uses $seqName as the name of the sequence. GenID() will automatically 
-	create the sequence for you if it does not exist (provided the userid has 
-	permission to do so). Otherwise you will have to create the sequence yourself. 
-<p> If your database driver emulates sequences, the name of the table is the sequence 
-	name. The table has one column, "id" which should be of type integer, or if 
-	you need something larger - numeric(16). 
-<p> For ODBC and databases that do not support sequences natively (eg mssql, mysql), 
-	we create a table for each sequence. If the sequence has not been defined 
-	earlier, it is created with the starting value set in $startID.</p>
-<p>Note that the mssql driver's GenID() before 1.90 used to generate 16 byte GUID's.</p>
-<p><b>UpdateBlob<a name="updateblob"></a>($table,$column,$val,$where)</b></p>
-Allows you to store a blob (in $val) into $table into $column in a row at $where. 
-<p> Usage: 
-<p> 
-<pre>
-	# for oracle
-	$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, empty_blob())');
-	$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
-	
-	# non oracle databases
-	$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)');
-	$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
-</pre>
-<p> Returns true if succesful, false otherwise. Supported by MySQL, PostgreSQL, 
-	Oci8, Oci8po and Interbase drivers. Other drivers might work, depending on 
-	the state of development.</p>
-<p>Note that when an Interbase blob is retrieved using SELECT, it still needs 
-	to be decoded using $connection->DecodeBlob($blob); to derive the original 
-	value in versions of PHP before 4.1.0. 
-<p>For PostgreSQL, you can store your blob using blob oid's or as a bytea field. 
-	You can use bytea fields but not blob oid's currently with UpdateBlob( ). 
-	Conversely UpdateBlobFile( ) supports oid's, but not bytea data.<br>
-	<br>
-	If you do not pass in an oid, then UpdateBlob() assumes that you are storing 
-	in bytea fields.
-<p><b>UpdateClob<a name="updateclob"></a>($table,$column,$val,$where)</b></p>
-Allows you to store a clob (in $val) into $table into $column in a row at $where. 
-Similar to UpdateBlob (see above), but for Character Large OBjects. 
-<p> Usage:
-<pre>
-	# for oracle
-	$conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, empty_clob())');
-	$conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
-	
-	# non oracle databases
-	$conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, null)');
-	$conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
-</pre>
-<p><b>UpdateBlobFile<a name="updateblobfile"></a>($table,$column,$path,$where,$blobtype='BLOB')</b></p>
-<p>Similar to UpdateBlob, except that we pass in a file path to where the blob 
-	resides.
-<p>For PostgreSQL, if you are using blob oid's, use this interface. This interface 
-	does not support bytea fields.
-<p>Returns true if successful, false otherwise. 
-<p><b>BlobEncode<a name="blobencode" id="blobencode"></a>($blob)</b> 
-<p>Some databases require blob's to be encoded manually before upload. Note if 
-	you use UpdateBlob( ) or UpdateBlobFile( ) the conversion is done automatically 
-	for you and you do not have to call this function. For PostgreSQL, currently, 
-	BlobEncode() can only be used for bytea fields.
-<p>Returns the encoded blob value.
-<p>Note that there is a connection property called <em>blobEncodeType</em> which 
-	has 3 legal values: 
-<p>false - no need to perform encoding or decoding.<br>
-	'I' - blob encoding required, and returned encoded blob is a numeric value 
-	(no need to quote).<br>
-	'C' - blob encoding required, and returned encoded blob is a character value 
-	(requires quoting).
-<p>This is purely for documentation purposes, so that programs that accept multiple 
-	database drivers know what is the right thing to do when processing blobs.
-<p><strong>BlobDecode<a name="blobdecode"></a>($blob)</strong> 
-</font><p><font color="#000000">Some databases require blob's to be decoded manually after doing a select statement. 
-	If the database does not require decoding, then this function will return 
-	the blob unchanged. Currently BlobDecode is only required for one database, 
-	PostgreSQL, and only if you are using blob oid's (if you are using bytea fields, 
-	we auto-decode for you).</font><font color="#000000">
-<pre>$rs = $db-&gt;Execute(&quot;select bloboid from postgres_table where id=$key&quot;);
-$blob = $db-&gt;BlobDecode( reset($rs-&gt;fields) );</pre>
-<p><b>Replace<a name="replace"></a>($table, $arrFields, $keyCols,$autoQuote=false)</b></p>
-<p>Try to update a record, and if the record is not found, an insert statement 
-	is generated and executed. Returns 0 on failure, 1 if update statement worked, 
-	2 if no record was found and the insert was executed successfully. This differs 
-	from MySQL's replace which deletes the record and inserts a new record. This 
-	also means you cannot update the primary key. The only exception to this is 
-	Interbase and its derivitives, which uses delete and insert because of some 
-	Interbase API limitations. 
-<p>The parameters are $table which is the table name, the $keyCols which is an 
-	associative array where the keys are the field names, and keyCols is the name 
-	of the primary key, or an array of field names if it is a compound key. If 
-	$autoQuote is set to true, then Replace() will quote all values that are non-numeric; 
-	auto-quoting will not quote nulls. Note that auto-quoting will not work if 
-	you use SQL functions or operators. 
-<p>Examples: 
-<pre>
-# single field primary key
-$ret = $db->Replace('atable', 
-	array('id'=>1000,'firstname'=>'Harun','lastname'=>'Al-Rashid'),
-	'id',$autoquote = true);	
-# generates UPDATE atable SET firstname='Harun',lastname='Al-Rashid' WHERE id=1000
-# or INSERT INTO atable (id,firstname,lastname) VALUES (1000,'Harun','Al-Rashid')
-
-# compound key
-$ret = $db->Replace('atable2', 
-	array('firstname'=>'Harun','lastname'=>'Al-Rashid', 'age' => 33, 'birthday' => 'null'),
-	array('lastname','firstname'),
-	$autoquote = true);
-
-# no auto-quoting
-$ret = $db->Replace('atable2', 
-	array('firstname'=>"'Harun'",'lastname'=>"'Al-Rashid'", 'age' => 'null'),
-	array('lastname','firstname'));	
-</pre>
-<p><b>GetUpdateSQL<a name="getupdatesql"></a>(&$rs, $arrFields, $forceUpdate=false,$magicq=false)</b></p>
-<p>Generate SQL to update a table given a recordset $rs, and the modified fields 
-	of the array $arrFields (which must be an associative array holding the column 
-	names and the new values) are compared with the current recordset. If $forceUpdate 
-	is true, then we also generate the SQL even if $arrFields is identical to 
-	$rs-&gt;fields. Requires the recordset to be associative. $magicq is used 
-	to indicate whether magic quotes are enabled (see qstr()). The field names in the array

-<p><b>Close<a name="close"></a>( )</b></p>
-<p>Close the database connection. PHP4 proudly states that we no longer have to 
-  clean up at the end of the connection because the reference counting mechanism 
-  of PHP4 will automatically clean up for us.</p>
-  <p><b>StartTrans<a name="starttrans"></a>( )</b></p>
-  <p>Start a monitored transaction. As SQL statements are executed, ADOdb will monitor
-  for SQL errors, and if any are detected, when CompleteTrans() is called, we auto-rollback.
-  <p>
-  <p> To understand why StartTrans() is superior to BeginTrans(), 
-  let us examine a few ways of using BeginTrans().
-  The following is the wrong way to use transactions: 
-<pre>
-$DB->BeginTrans();
-$DB->Execute("update table1 set val=$val1 where id=$id");
-$DB->Execute("update table2 set val=$val2 where id=$id");
-$DB->CommitTrans();
-</pre>
-<p>because you perform no error checking. It is possible to update table1 and 
-  for the update on table2 to fail. Here is a better way: 
-<pre>
-$DB->BeginTrans();
-$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
-if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
-if ($ok) $DB->CommitTrans();
-else $DB->RollbackTrans();
-</pre>
-<p>Another way is (since ADOdb 2.0): 
-<pre>
-$DB->BeginTrans();
-$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
-if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
-$DB->CommitTrans($ok);
-</pre>
-<p> Now it is a headache monitoring $ok all over the place. StartTrans() is an
-improvement because it monitors all SQL errors for you. This is particularly
-useful if you are calling black-box functions in which SQL queries might be executed.
- Also all BeginTrans, CommitTrans and RollbackTrans calls inside a StartTrans block 
-  will be disabled, so even if the black box function does a commit, it will be ignored.
-<pre>
-$DB->StartTrans();
-CallBlackBox();
-$DB->Execute("update table1 set val=$val1 where id=$id");
-$DB->Execute("update table2 set val=$val2 where id=$id");
-$DB->CompleteTrans($ok);
-</pre>
-<p>Note that a StartTrans blocks are nestable, the inner blocks are ignored.
- <p><b>CompleteTrans<a name="completetrans"></a>($autoComplete=true)</b></p>
-  <p>Complete a transaction called with StartTrans(). This function monitors
-  for SQL errors, and will commit if no errors have occured, otherwise it will rollback. 
-  Returns true on commit, false on rollback. If the parameter $autoComplete is true
-  monitor sql errors and commit and rollback as appropriate. Set $autoComplete to false 
-  to force rollback even if no SQL error detected.
-  <p><b>FailTrans<a name="failtrans"></a>( )</b></p>
-  <p>Fail a transaction started with StartTrans(). The rollback will only occur when
-  CompleteTrans() is called.
-    <p><b>HasFailedTrans<a name="hasfailedtrans"></a>( )</b></p>
-	<p>Check whether smart transaction has failed, 
-	eg. returns true if there was an error in SQL execution or FailTrans() was called.
-	If not within smart transaction, returns false.
-<p><b>BeginTrans<a name="begintrans"></a>( )</b></p>
-<p>Begin a transaction. Turns off autoCommit. Returns true if successful. Some 
-  databases will always return false if transaction support is not available. 
-   Any open transactions will be rolled back when the connection is closed. Among the
-   databases that support transactions are Oracle, PostgreSQL, Interbase, MSSQL, certain
-    versions of MySQL, DB2, Informix, Sybase, etc.</p>
- <p>Note that <a href=#starttrans>StartTrans()</a> and CompleteTrans() is a superior method of 
- handling transactions, available since ADOdb 3.40. For a explanation, see the <a href=#starttrans>StartTrans()</a> documentation.
-
-<p>You can also use the ADOdb <a href=#errorhandling>error handler</a> to die 
-  and rollback your transactions for you transparently. Some buggy database extensions 
-  are known to commit all outstanding tranasactions, so you might want to explicitly 
-  do a $DB->RollbackTrans() in your error handler for safety. 
- <h4>Detecting Transactions</h4>
- <p>Since ADOdb 2.50, you are able to detect when you are inside a transaction. Check
- that $connection->transCnt > 0. This variable is incremented whenever BeginTrans() is called,
- and decremented whenever RollbackTrans() or CommitTrans() is called.
-<p><b>CommitTrans<a name="committrans"></a>($ok=true)</b></p>
-<p>End a transaction successfully. Returns true if successful. If the database 
-  does not support transactions, will return true also as data is always committed. 
-</p>
-<p>If you pass the parameter $ok=false, the data is rolled back. See example in 
-  BeginTrans().</p>
-<p><b>RollbackTrans<a name="rollbacktrans"></a>( )</b></p>
-<p>End a transaction, rollback all changes. Returns true if successful. If the 
-  database does not support transactions, will return false as data is never rollbacked.

-Binds a PHP variable as input to a stored procedure variable. The parameter <i>$stmt</i>
- is the value returned by PrepareSP(), <i>$var</i> is the PHP variable you want to bind, $name
- is the name of the stored procedure variable. Optional is <i>$maxLen</i>, the maximum length of the

-  <p>Here is an example using oci8:
-  <pre><font color="green"># For oracle, Prepare and PrepareSP are identical</font>

-$db-&gt;OutParameter($stmt,$ret,'RETVAL');
-$db-&gt;Execute($stmt); </font></pre>
-
-<p>Note that the only difference between the oci8 and mssql implementations is $sql.</p>
-  <p>
- If $type parameter is set to false, in mssql, $type will be dynamicly determined 
-based on the type of the PHP variable passed <font face="Courier New, Courier, mono">(string 
-=&gt; SQLCHAR, boolean =&gt;SQLINT1, integer =&gt;SQLINT4 or float/double=&gt;SQLFLT8)</font>.
-<p> 
-In oci8, $type can be set to OCI_B_FILE (Binary-File), OCI_B_CFILE (Character-File), 
-OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and OCI_B_ROWID (ROWID). To

-  Binds a PHP variable as output from a stored procedure variable. The parameter <i>$stmt</i>
- is the value returned by PrepareSP(), <i>$var</i> is the PHP variable you want to bind, <i>$name</i>

-<p>Note: This function is deprecated, because of the new InParameter() and OutParameter() functions.
-These are superior because they are self-documenting, unlike Parameter().
-<p>Adds a bind parameter suitable for return values or special data handling (eg. 
-  LOBs) after a statement has been prepared using PrepareSP(). Only for mssql 
-  and oci8 currently. The parameters are:<br>
-  <br>
-  $<i><b>stmt</b></i> Statement returned by Prepare() or PrepareSP().<br>
-  $<i><b>var</b></i> PHP variable to bind to. Make sure you pre-initialize it!<br>
-  $<i><b>name</b></i> Name of stored procedure variable name to bind to.<br>
-  [$<i><b>isOutput</b></i>] Indicates direction of parameter 0/false=IN 1=OUT 
-  2= IN/OUT. This is ignored in oci8 as this driver auto-detects the direction.<br>
-  [$<b>maxLen</b>] Maximum length of the parameter variable.<br>

-	$conn->LogSQL(); // turn on logging
-	  :
-	$conn->Execute(...);
-	  :
-	$conn->LogSQL(false); // turn off logging
-	
-	# output summary of SQL logging results
-	$perf = NewPerfMonitor($conn);

-	echo $perf->ExpensiveSQL();
-</pre>
-<p>One limitation of logging is that rollback also prevents SQL from being logged.
-<p>
-If you prefer to use another name for the table used to store the SQL, you can override it by calling 
-adodb_perf::table($tablename), where $tablename is the new table name (you will still need to manually
-create the table yourself). An example:
-<pre>
-	include('adodb.inc.php');
-	include('adodb-perf.inc.php');
-	adodb_perf::table('my_logsql_table');
-</pre>

-<p><font color="#000000"><b>fnExecute and fnCacheExecute properties<a name="fnexecute" id="fnexecute"></a></b></font></p>
-<p>These two properties allow you to define bottleneck functions for all sql statements 
-  processed by ADOdb. This allows you to perform statistical analysis and query-rewriting 
-  of your sql. 
-<p><b>Examples of fnExecute</b></p>
-<p>Here is an example of using fnExecute, to count all cached queries and non-cached 
-  queries, you can do this:</p>
-<pre><font color="#006600"># $db is the connection object</font>
-function CountExecs($db, $sql, $inputarray)
-{
-global $EXECS;
-
-if (!is_array(inputarray)) $EXECS++;
-<font color="#006600"># handle 2-dimensional input arrays</font>
-else if (is_array(reset($inputarray))) $EXECS += sizeof($inputarray);
-else $EXECS++;
-}
-
-<font color="#006600"># $db is the connection object</font>
-function CountCachedExecs($db, $secs2cache, $sql, $inputarray)
-{<br>global $CACHED; $CACHED++;
-}
-<br>$db = NewADOConnection('mysql');
-$db-&gt;Connect(...);
-$db-&gt;<strong>fnExecute</strong> = 'CountExecs';
-$db-&gt;<strong>fnCacheExecute</strong> = 'CountCachedExecs';
- :
- :<br><font color="#006600"># After many sql statements:</font>`
-printf(&quot;&lt;p&gt;Total queries=%d; total cached=%d&lt;/p&gt;&quot;,$EXECS+$CACHED, $CACHED);
-</pre>
-<p>The fnExecute function is called before the sql is parsed and executed, so 
-  you can perform a query rewrite. If you are passing in a prepared statement, 
-  then $sql is an array (see <a href="#prepare">Prepare</a>). The fnCacheExecute 
-  function is only called if the recordset returned was cached.<font color="#000000"> 
-  The function parameters match the Execute and CacheExecute functions respectively, 
-  except that $this (the connection object) is passed as the first parameter.</font></p>
-<p>Since ADOdb 3.91, the behaviour of fnExecute varies depending on whether the 
-  defined function returns a value. If it does not return a value, then the $sql 
-  is executed as before. This is useful for query rewriting or counting sql queries. 
-<p> On the other hand, you might want to replace the Execute function with one 
-  of your own design. If this is the case, then have your function return a value. 
-  If a value is returned, that value is returned immediately, without any further 
-  processing. This is used internally by ADOdb to implement LogSQL() functionality.

-<h3>ADOConnection Utility Functions</h3>
-<p><b>BlankRecordSet<a name="blankrecordset"></a>([$queryid])</b></p>
-<p>No longer available - removed since 1.99.</p>
-<p><b>Concat<a name="concat"></a>($s1,$s2,....)</b></p>
-<p>Generates the sql string used to concatenate $s1, $s2, etc together. Uses the 
-  string in the concat_operator field to generate the concatenation. Override 
-  this function if a concatenation operator is not used, eg. MySQL.</p>
-<p>Returns the concatenated string.</p>
-<p><b>DBDate<a name="dbdate"></a>($date)</b></p>
-<p>Format the $<b>date</b> in the format the database accepts. This is used in 
-  INSERT/UPDATE statements; for SELECT statements, use <a href="#sqldate">SQLDate</a>. 
-  The $<b>date</b> parameter can be a Unix integer timestamp or an ISO format 
-  Y-m-d. Uses the fmtDate field, which holds the format to use. If null or false 
-  or '' is passed in, it will be converted to an SQL null.</p>
-<p>Returns the date as a quoted string.</p>
-<p><b>DBTimeStamp<a name="dbtimestamp"></a>($ts)</b></p>
-<p>Format the timestamp $<b>ts</b> in the format the database accepts; this can 
-  be a Unix integer timestamp or an ISO format Y-m-d H:i:s. Uses the fmtTimeStamp 
-  field, which holds the format to use. If null or false or '' is passed in, it 
-  will be converted to an SQL null.</p>
-<p>Returns the timestamp as a quoted string.</p>
-<p><b>qstr<a name="qstr"></a>($s,[$magic_quotes_enabled</b>=false]<b>)</b></p>
-<p>Quotes a string to be sent to the database. The $<b>magic_quotes_enabled</b> 
-  parameter may look funny, but the idea is if you are quoting a string extracted 
-  from a POST/GET variable, then pass get_magic_quotes_gpc() as the second parameter. 
-  This will ensure that the variable is not quoted twice, once by <i>qstr</i> 
-  and once by the <i>magic_quotes_gpc</i>.</p>
-<p>Eg.<font face="Courier New, Courier, mono"> $s = $db-&gt;qstr(HTTP_GET_VARS['name'],get_magic_quotes_gpc());</font></p>
-<p>Returns the quoted string.</p>
-<p><b>Quote<a name="quote"></a>($s)</b></p>
-<p>Quotes the string $s, escaping the database specific quote character as appropriate. 
-  Formerly checked magic quotes setting, but this was disabled since 3.31 for 
-  compatibility with PEAR DB. 
-<p><b>Affected_Rows<a name="affected_rows"></a>( )</b></p>
-<p>Returns the number of rows affected by a update or delete statement. Returns 
-  false if function not supported.</p>
-<p>Not supported by interbase/firebird currently. </p>
-<p><b>Insert_ID<a name="inserted_id"></a>( )</b></p>
-<p>Returns the last autonumbering ID inserted. Returns false if function not supported. 
-</p>
-<p>Only supported by databases that support auto-increment or object id's, such 
-  as PostgreSQL, MySQL and MS SQL Server currently. PostgreSQL returns the OID, which 
-  can change on a database reload.</p>
-<p><b>RowLock<a name="rowlock"></a>($table,$where)</b></p>
-<p>Lock a table row for the duration of a transaction. For example to lock record $id in table1:
-<pre>
-	$DB->StartTrans();
-	$DB->RowLock("table1","rowid=$id");
-	$DB->Execute($sql1);
-	$DB->Execute($sql2);
-	$DB->CompleteTrans();
-</pre>
-<p>Supported in db2, interbase, informix, mssql, oci8, postgres, sybase.
-<p><b>MetaDatabases<a name="metadatabases"></a>()</b></p>
-<p>Returns a list of databases available on the server as an array. You have to 
-  connect to the server first. Only available for ODBC, MySQL and ADO.</p>
-<p><b>MetaTables<a name="metatables"></a>($ttype = false, $showSchema = false, 
-  $mask=false)</b></p>
-<p>Returns an array of tables and views for the current database as an array. 
-  The array should exclude system catalog tables if possible. To only show tables, 
-  use $db->MetaTables('TABLES'). To show only views, use $db->MetaTables('VIEWS'). 
-  The $showSchema parameter currently works only for DB2, and when set to true, 
-  will add the schema name to the table, eg. "SCHEMA.TABLE". </p>
-<p>You can define a mask for matching. For example, setting $mask = 'TMP%' will 
-  match all tables that begin with 'TMP'. Currently only mssql, oci8, odbc_mssql 
-  and postgres* support $mask. 
-<p><b>MetaColumns<a name="metacolumns"></a>($table,$toupper=true)</b></p>
-<p>Returns an array of ADOFieldObject's, one field object for every column of 
-  $table. A field object is a class instance with (name, type, max_length) defined.
-  Currently Sybase does not recognise date types, and ADO cannot identify 
-  the correct data type (so we default to varchar).   
- <p> The $toupper parameter determines whether we uppercase the table name 
- (required for some databases).
- <p>For schema support, pass in the $table parameter, "$schema.$tablename". This is only
- supported for selected databases.
-<p><b>MetaColumnNames<a name="metacolumnames"></a>($table)</b></p>
-<p>Returns an array of column names for $table. 
-<p><font color="#000000"><b>MetaPrimaryKeys<a name="metaprimarykeys"></a>($table, 
-  $owner=false)</b></font></font> 
-<p><font color="#000000">Returns an array containing column names that are the 
-  primary keys of $table. Supported by mysql, odbc (including db2, odbc_mssql, 
-  etc), mssql, postgres, interbase/firebird, oci8 currently. </font><font color="#000000"> 
-<p>Views (and some tables) have primary keys, but sometimes this information is not available from the
-database. You can define a function  ADODB_View_PrimaryKeys($databaseType, $database, $view, $owner) that
-should return an array containing the fields that make up the primary key. If that function exists,
-it will be called when MetaPrimaryKeys() cannot find a primary key for a table or view.
-<pre>
-// In this example: dbtype = 'oci8', $db = 'mydb', $view = 'dataView', $owner = false 
-function ADODB_View_PrimaryKeys($dbtype,$db,$view,$owner)
-{

-$db->MetaPrimaryKeys('dataView');
-</pre>
-<p><font color="#000000"><b>ServerInfo<a name="serverinfo" id="serverinfo"></a>($table)</b></font></font> 
-<p><font color="#000000">Returns an array of containing two elements 'description' 
-  and 'version'. The 'description' element contains the string description of 
-  the database. The 'version' naturally holds the version number (which is also 
-  a string).</font><font color="#000000"> 
-<p><b>MetaForeignKeys<a name="metaforeignkeys"></a>($table, $owner=false, $upper=false)</b> 
-<p>Returns an associate array of foreign keys, or false if not supported. For 
-  example, if table employee has a foreign key where employee.deptkey points to 
-  dept_table.deptid, and employee.posn=posn_table.postionid and employee.poscategory=posn_table.category, 
-  then $conn->MetaForeignKeys('employee') will return 
-<pre>
-	array(
-		'dept_table' => array('deptkey=deptid'),
-		'posn_table' => array('posn=positionid','poscategory=category')
-	)
-</pre>
-<p>The optional schema or owner can be defined in $owner. If $upper is true, then 
-  the table names (array keys) are upper-cased.

-<h2>ADORecordSet<a name="adorecordset"></a></h2>
-<p>When an SQL statement successfully is executed by <font face="Courier New, Courier, mono">ADOConnection-&gt;Execute($sql),</font>an 
-  ADORecordSet object is returned. This object contains a virtual cursor so we 
-  can move from row to row, functions to obtain information about the columns 
-  and column types, and helper functions to deal with formating the results to 
-  show to the user.</p>
-<h3>ADORecordSet Fields</h3>
-<p><b>fields: </b>Array containing the current row. This is not associative, but 
-  is an indexed array from 0 to columns-1. See also the function <b><a href="#fields">Fields</a></b>, 
-  which behaves like an associative array.</p>
-<p><b>dataProvider</b>: The underlying mechanism used to connect to the database. 
-  Normally set to <b>native</b>, unless using <b>odbc</b> or <b>ado</b>.</p>
-<p><b>blobSize</b>: Maximum size of a char, string or varchar object before it 
-  is treated as a Blob (Blob's should be shown with textarea's). See the <a href="#metatype">MetaType</a> 
-  function.</p>
-<p><b>sql</b>: Holds the sql statement used to generate this record set.</p>
-<p><b>canSeek</b>: Set to true if Move( ) function works.</p>
-<p><b>EOF</b>: True if we have scrolled the cursor past the last record.</p>
-<h3>ADORecordSet Functions</h3>
-<p><b>ADORecordSet( )</b></p>
-<p>Constructer. Normally you never call this function yourself.</p>
-<p><b>GetAssoc<a name="getassoc"></a>([$force_array])</b></p>
-<p>Generates an associative array from the recordset. Note that is this function 
-  is also <a href="#getassoc1">available</a> in the connection object. More details 
-  can be found there.</p>

-<p><b>GetArray<a name="getarray"></a>([$number_of_rows])</b></p>
-<p>Generate a 2-dimensional array of records from the current cursor position, 
-  indexed from 0 to $number_of_rows - 1. If $number_of_rows is undefined, till 
-  EOF.</p>
-<p><b>GetRows<a name="getrows"></a>([$number_of_rows])</b></p>
-Generate a 2-dimensional array of records from the current cursor position. Synonym 
-for GetArray() for compatibility with Microsoft ADO. 
-<p> <b>GetMenu<a name="getmenu"></a>($name, [$default_str=''], [$blank1stItem=true], 
-  [$multiple_select=false], [$size=0], [$moreAttr=''])</b></p>
-<p>Generate a HTML menu (&lt;select&gt;&lt;option&gt;&lt;option&gt;&lt;/select&gt;). 
-  The first column of the recordset (fields[0]) will hold the string to display 
-  in the option tags. If the recordset has more than 1 column, the second column 
-  (fields[1]) is the value to send back to the web server.. The menu will be given 
-  the name $<i>name</i>. 
-<p> If $<i>default_str</i> is defined, then if $<i>default_str</i> == fields[0], 
-  that field is selected. If $<i>blank1stItem</i> is true, the first option is 
-  empty. You can also set the first option strings by setting $blank1stItem = 
-  "$value:$text".</p>
-<p>$<i>Default_str</i> can be array for a multiple select listbox.</p>
-<p>To get a listbox, set the $<i>size</i> to a non-zero value (or pass $default_str 
-  as an array). If $<i>multiple_select</i> is true then a listbox will be generated 
-  with $<i>size</i> items (or if $size==0, then 5 items) visible, and we will 
-  return an array to a server. Lastly use $<i>moreAttr </i> to add additional 
-  attributes such as javascript or styles. </p>
-<p>Menu Example 1: <code>GetMenu('menu1','A',true)</code> will generate a menu: 
-  <select name='menu1'>
-    <option> 
-    <option value=1 selected>A 
-    <option value=2>B 
-    <option value=3>C 
-  </select>
-  for the data (A,1), (B,2), (C,3). Also see <a href="#ex5">example 5</a>.</p>
-<p>Menu Example 2: For the same data, <code>GetMenu('menu1',array('A','B'),false)</code> 
-  will generate a menu with both A and B selected: <br>
-  <select name='menu1' multiple size=3>
-    <option value=1 selected>A 
-    <option value=2 selected>B 
-    <option value=3>C 
-  </select>
-<p> <b>GetMenu2<a name="getmenu2"></a>($name, [$default_str=''], [$blank1stItem=true], 
-  [$multiple_select=false], [$size=0], [$moreAttr=''])</b></p>
-<p>This is nearly identical to GetMenu, except that the $<i>default_str</i> is 
-  matched to fields[1] (the option values).</p>
-<p>Menu Example 3: Given the data in menu example 2, <code>GetMenu2('menu1',array('1','2'),false)</code> 
-  will generate a menu with both A and B selected in menu example 2, but this 
-  time the selection is based on the 2nd column, which holds the values to return 
-  to the Web server. 
-<p><b>UserDate<a name="userdate"></a>($str, [$fmt])</b></p>
-<p>Converts the date string $<i>str</i> to another format. The date format is Y-m-d,
-or Unix timestamp format. The default $<i>fmt</i> is Y-m-d.</p>
-<p><b>UserTimeStamp<a name="usertimestamp"></a>($str, [$fmt])</b></p>
-<p>Converts the timestamp string $<b>str</b> to another format. The timestamp 
-  format is Y-m-d H:i:s, as in '2002-02-28 23:00:12', or Unix timestamp format.
-   UserTimeStamp calls UnixTimeStamp to parse $<i>str</i>, and $<i>fmt</i> defaults to Y-m-d H:i:s if not defined. 
-</p>
-<p><b>UnixDate<a name="unixdate"></a>($str)</b></p>
-<p>Parses the date string $<b>str</b> and returns it in unix mktime format (eg. 
-  a number indicating the seconds after January 1st, 1970). Expects the date to 
-  be in Y-m-d H:i:s format, except for Sybase and Microsoft SQL Server, where 
-  M d Y is also accepted (the 3 letter month strings are controlled by a global 
-  array, which might need localisation).</p>
-<p>This function is available in both ADORecordSet and ADOConnection since 1.91.</p>
-<p><b>UnixTimeStamp<a name="unixtimestamp"></a>($str)</b></p>
-<p>Parses the timestamp string $<b>str</b> and returns it in unix mktime format

- h: Hour (1-12)
- i: Minute (00-59)
- s: Second (00-60)
- A: AM/PM indicator</pre>
-<p>All other characters are treated as strings. You can also use \ to escape characters. 
-  Available on selected databases, including mysql, postgresql, mssql, oci8 and 
-  DB2. 
-<p>This is useful in writing portable sql statements that GROUP BY on dates. For 
-  example to display total cost of goods sold broken by quarter (dates are stored

-<p><b>MoveNext<a name="movenext"></a>( )</b></p>
-<p>Move the internal cursor to the next row. The <i>$this->fields</i> array is 
-  automatically updated. Returns false if unable to do so (normally because EOF 
-  has been reached), otherwise true. 
-<p> If EOF is reached, then the $this->fields array is set to false (this was 
-  only implemented consistently in ADOdb 3.30). For the pre-3.30 behaviour of

- 		ProcessArray($rs->fields);	
-		$rs->MoveNext();
-	} </pre>
-<p><b>Move<a name="move"></a>($to)</b></p>
-<p>Moves the internal cursor to a specific row $<b>to</b>. Rows are zero-based 
-  eg. 0 is the first row. The <b>fields</b> array is automatically updated. For 
-  databases that do not support scrolling internally, ADOdb will simulate forward 
-  scrolling. Some databases do not support backward scrolling. If the $<b>to</b> 
-  position is after the EOF, $<b>to</b> will move to the end of the RecordSet 
-  for most databases. Some obscure databases using odbc might not behave this 
-  way.</p>
-<p>Note: This function uses <i>absolute positioning</i>, unlike Microsoft's ADO.</p>
-<p>Returns true or false. If false, the internal cursor is not moved in most implementations, 
-  so AbsolutePosition( ) will return the last cursor position before the Move( 
-  ). </p>
-<p><b>MoveFirst<a name="movefirst"></a>()</b></p>
-<p>Internally calls Move(0). Note that some databases do not support this function.</p>
-<p><b>MoveLast<a name="movelast"></a>()</b></p>
-<p>Internally calls Move(RecordCount()-1). Note that some databases do not support 
-  this function.</p>
-<p><b>GetRowAssoc</b><a name="getrowassoc"></a>($toUpper=true)</p>
-<p>Returns an associative array containing the current row. The keys to the array 
-  are the column names. The column names are upper-cased for easy access. To get 
-  the next row, you will still need to call MoveNext(). </p>
-<p>For example:<br>
-  Array ( [ID] => 1 [FIRSTNAME] => Caroline [LASTNAME] => Miranda [CREATED] => 
-  2001-07-05 ) </p>
-<p>Note: do not use GetRowAssoc() with $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC.

-<p>Returns the number of fields (columns) in the record set.</p>
-<p><b>RecordCount<a name="recordcount"></a>( )</b></p>
-<p>Returns the number of rows in the record set. If the number of records returned 
-  cannot be determined from the database driver API, we will buffer all rows and 
-  return a count of the rows after all the records have been retrieved. This buffering 
-  can be disabled (for performance reasons) by setting the global variable $ADODB_COUNTRECS 
-  = false. When disabled, RecordCount( ) will return -1 for certain databases. 
-  See the supported databases list above for more details. </p>
-<p> RowCount is a synonym for RecordCount.</p>
-<p><b>PO_RecordCount<a name="po_recordcount"></a>($table, $where)</b></p>

-<p>Determine what <i>generic</i> meta type a database field type is given its 
-  native type $<b>nativeDBType</b> as a string and the length of the field $<b>field_max_length</b>. 
-  Note that field_max_length can be -1 if it is not known. The field object returned 
-  by FetchField() can be passed in $<b>fieldobj</b> or as the 1st parameter <b>$nativeDBType</b>. 
-  This is useful for databases such as <i>mysql</i> which has additional properties 
-  in the field object such as <i>primary_key</i>. </p>
-<p>Uses the field <b>blobSize</b> and compares it with $<b>field_max_length</b> 
-  to determine whether the character field is actually a blob.</p>
-For example, $db-&gt;MetaType('char') will return 'C'. 
-<p>Returns:</p>
-<ul>
-  <li><b>C</b>: Character fields that should be shown in a &lt;input type=&quot;text&quot;&gt;

-If memory management is not an issue, you do not need to call this function as recordsets

-<h3>function rs2html<a name="rs2html"></a>($adorecordset,[$tableheader_attributes],

-<p>This is a standalone function (rs2html = recordset to html) that is similar 
-  to PHP's <i>odbc_result_all</i> function, it prints a ADORecordSet, $<b>adorecordset</b> 
-  as a HTML table. $<b>tableheader_attributes</b> allow you to control the table 
-  <i>cellpadding</i>, <i>cellspacing</i> and <i>border</i> attributes. Lastly 
-  you can replace the database column names with your own column titles with the 
-  array $<b>col_titles</b>. This is designed more as a quick debugging mechanism, 
-  not a production table recordset viewer.</p>
-<p>You will need to include the file <i>tohtml.inc.php</i>.</p>

-<h3>Differences between this ADOdb library and Microsoft ADO<a name="adodiff"></a></h3>
-<ol>
-  <li>ADOdb only supports recordsets created by a connection object. Recordsets 
-    cannot be created independently.</li>
-  <li>ADO properties are implemented as functions in ADOdb. This makes it easier 
-    to implement any enhanced ADO functionality in the future.</li>
-  <li>ADOdb's <font face="Courier New, Courier, mono">ADORecordSet-&gt;Move()</font> 
-    uses absolute positioning, not relative. Bookmarks are not supported.</li>
-  <li><font face="Courier New, Courier, mono">ADORecordSet-&gt;AbsolutePosition() 
-    </font>cannot be used to move the record cursor.</li>
-  <li>ADO Parameter objects are not supported. Instead we have the ADOConnection::<a href="#parameter">Parameter</a>( 
-    ) function, which provides a simpler interface for calling preparing parameters 
-    and calling stored procedures.</li>
-  <li>Recordset properties for paging records are available, but implemented as 
-    in <a href=#ex8>Example 8</a>.</li>

-<h1>Database Driver Guide<a name="driverguide"></a></h1>
-<p>This describes how to create a class to connect to a new database. To ensure 
-  there is no duplication of work, kindly email me at jlim#natsoft.com.my if you 
-  decide to create such a class.</p>
-<p>First decide on a name in lower case to call the database type. Let's say we 
-  call it xbase. </p>
-<p>Then we need to create two classes ADODB_xbase and ADORecordSet_xbase in the 
-  file adodb-xbase.inc.php.</p>
-<p>The simplest form of database driver is an adaptation of an existing ODBC driver. 
-  Then we just need to create the class <i>ADODB_xbase extends ADODB_odbc</i> 
-  to support the new <b>date</b> and <b>timestamp</b> formats, the <b>concatenation</b> 
-  operator used, <b>true</b> and <b>false</b>. For the<i> ADORecordSet_xbase extends 
-  ADORecordSet_odbc </i>we need to change the <b>MetaType</b> function. See<b> 
-  adodb-vfp.inc.php</b> as an example.</p>
-<p>More complicated is a totally new database driver that connects to a new PHP 
-  extension. Then you will need to implement several functions. Fortunately, you 
-  do not have to modify most of the complex code. You only need to override a 
-  few stub functions. See <b>adodb-mysql.inc.php</b> for example.</p>
-<p>The default date format of ADOdb internally is YYYY-MM-DD (Ansi-92). All dates 
-  should be converted to that format when passing to an ADOdb date function. See 
-  Oracle for an example how we use ALTER SESSION to change the default date format 
-  in _pconnect _connect.</p>
-<p><b>ADOConnection Functions to Override</b></p>
-<p>Defining a constructor for your ADOConnection derived function is optional. 
-  There is no need to call the base class constructor.</p>
-<p>_<b>connect</b>: Low level implementation of Connect. Returns true or false. 
-  Should set the _<b>connectionID</b>.</p>
-<p>_<b>pconnect:</b> Low level implemention of PConnect. Returns true or false. 
-  Should set the _<b>connectionID</b>.</p>
-<p>_<b>query</b>: Execute a query. Returns the queryID, or false.</p>
-<p>_<b>close: </b>Close the connection -- PHP should clean up all recordsets. 
-</p>
-<p><b>ErrorMsg</b>: Stores the error message in the private variable _errorMsg. 
-</p>
-<p><b>ADOConnection Fields to Set</b></p>
-<p>_<b>bindInputArray</b>: Set to true if binding of parameters for SQL inserts 
-  and updates is allowed using ?, eg. as with ODBC.</p>
-<p><b>fmtDate</b></p>
-<p><b>fmtTimeStamp</b></p>
-<p><b>true</b></p>
-<p><b>false</b></p>
-<p><b>concat_operator</b></p>
-<p><b>replaceQuote</b></p>
-<p><b>hasLimit</b> support SELECT * FROM TABLE LIMIT 10 of MySQL.</p>
-<p><b>hasTop</b> support Microsoft style SELECT TOP 10 * FROM TABLE.</p>
-<p><b>ADORecordSet Functions to Override</b></p>
-<p>You will need to define a constructor for your ADORecordSet derived class that 
-  calls the parent class constructor.</p>
-<p><b>FetchField: </b> as documented above in ADORecordSet</p>
-<p>_<b>initrs</b>: low level initialization of the recordset: setup the _<b>numOfRows</b> 
-  and _<b>numOfFields</b> fields -- called by the constructor.</p>
-<p>_<b>seek</b>: seek to a particular row. Do not load the data into the fields 
-  array. This is done by _fetch. Returns true or false. Note that some implementations 
-  such as Interbase do not support seek. Set canSeek to false.</p>
-<p>_<b>fetch</b>: fetch a row using the database extension function and then move 
-  to the next row. Sets the <b>fields</b> array. If the parameter $ignore_fields 
-  is true then there is no need to populate the <b>fields</b> array, just move 
-  to the next row. then Returns true or false.</p>
-<p>_<b>close</b>: close the recordset</p>
-<p><b>Fields</b>: If the array row returned by the PHP extension is not an associative 
-  one, you will have to override this. See adodb-odbc.inc.php for an example. 
-  For databases such as MySQL and MSSQL where an associative array is returned, 
-  there is no need to override this function.</p>
-<p><b>ADOConnection Fields to Set</b></p>
-<p>canSeek: Set to true if the _seek function works.</p>

-<p><b>4.20 27 Feb 2004</b>
-<p>Updated to AXMLS 1.01.
-<p>MetaForeignKeys for postgres7 modified by Edward Jaramilla, works on pg 7.4.
-<p>Now numbers accepts function calls or sequences for GetInsertSQL/GetUpdateSQL numeric fields.
-<p>Changed quotes of 'delete from $perf_table' to "". Thx Kehui (webmaster#kehui.net)
-<p>Added ServerInfo() for ifx, and putenv trim fix. Thx Fernando Ortiz.
-<p>Added addq(), which is analogous to addslashes().
-<p>Tested with php5b4. Fix some php5 compat problems with exceptions and sybase.
-<P>Carl-Christian Salvesen added patch to mssql _query to support binds greater than 4000 chars.
-<p>Mike suggested patch to PHP5 exception handler. $errno must be numeric.
-<p>Added double quotes (") to ADODB_TABLE_REGEX.
-<p>For oci8, Prepare(...,$cursor), $cursor's meaning was accidentally inverted in 4.11. This causes problems with ExecuteCursor() too, which calls Prepare() internally. Thx to William Lovaton.
-<p>Now dateHasTime property in connection object renamed to datetime for consistency. This could break bc.
-<p>Csongor Halmai reports that db2 SelectLimit with input array is not working. Fixed..
-<p><b>4.11 27 Jan 2004</b>
-<p>Csongor Halmai reports db2 binding not working. Reverted back to emulated binding.
-<p>Dan Cech modifies datadict code. Adds support for DropIndex. Minor cleanups.
-<p>Table misspelt in perf-oci8.inc.php. Changed v$conn_cache_advice to v$db_cache_advice. Reported by Steve W.
-<p>UserTimeStamp and DBTimeStamp did not handle YYYYMMDDHHMMSS format properly. Reported by Mike Muir. Fixed.
-<p>Changed oci8 Prepare(). Does not auto-allocate OCINewCursor automatically, unless 2nd param is set to true.
-This will break backward compat, if Prepare/Execute is used instead of ExecuteCursor. Reported by Chris Jones.
-<p>Added InParameter() and OutParameter(). Wrapper functions to Parameter(), but nicer because they
-are self-documenting.
-<p>Added 'R' handling in ActualType() to datadict-mysql.inc.php
-<p>Added ADOConnection::SerializableRS($rs). Returns a recordset that can be serialized in a session.
-<p>Added "Run SQL" to performance UI().
-<p>Misc spelling corrections in adodb-mysqli.inc.php, adodb-oci8.inc.php and datadict-oci8.inc.php, from Heinz Hombergs.
-<p>MetaIndexes() for ibase contributed by Heinz Hombergs.
-<p><b>4.10 12 Jan 2004</b>
-<p>Dan Cech contributed extensive changes to data dictionary to support name quoting (with `), and drop table/index.
-<p>Informix added cursorType property. Default remains IFX_SCROLL, but you can change to 0 (non-scrollable cursor) for performance.
-<p>Added ADODB_View_PrimaryKeys() for returning view primary keys to MetaPrimaryKeys().
-<p>Simplified chinese file, adodb-cn.inc.php from cysoft.
-<p>Added check for ctype_alnum in adodb-datadict.inc.php. Thx to Jason Judge.

-  to odbc driver for DB2, including implementing serverinfo() and SQLDate(), switching 
-  to SQL_CUR_USE_ODBC as the cursor mode, and lastAffectedRows and SelectLimit() 
-  fixes. 
-<p>The odbc driver's FetchField() field names did not obey ADODB_ASSOC_CASE. Fixed. 
-<p>Some bugs in adodb_backtrace() fixed.

-<h2>ADOdb Data Dictionary Library for PHP</h2>
-<p>V4.20 22 Feb 2004 (c) 2000-2004 John Lim (<a href="mailto:jlim#natsoft.com.my">jlim#natsoft.com.my</a>).<br> AXMLS (c) 2004 ars Cognita, Inc</p>
-<p><font size="1">This software is dual licensed using BSD-Style and LGPL. This means you can use it in compiled proprietary and commercial products.</font></p>
-<p>Useful ADOdb links:  <a href=http://php.weblogs.com/adodb?dd=1>Download</a> &nbsp; <a href=http://php.weblogs.com/adodb_manual?dd=1>Other Docs</a></p>
-
-<p>This documentation describes a PHP class library to automate the creation of tables, 
-  indexes and foreign key constraints portably for multiple databases. Richard Tango-Lowy and Dan Cech
-  have been kind enough to contribute <a href=#xmlschema>AXMLS</a>, an XML schema system for defining databases.</p>
-
-<p>Currently the following databases are supported:</p>
-<p>
-  <b>Well-tested:</b> PostgreSQL, MySQL, Oracle, MSSQL.<br />
-  <b>Beta-quality:</b> DB2, Informix, Sybase, Interbase, Firebird.<br />
-  <b>Alpha-quality:</b> MS Access (does not support DEFAULT values) and generic ODBC.
-</p>
-
-<h3>Example Usage</h3>
-<pre>
-  include_once('adodb.inc.php');
-  <font color="#006600"># First create a normal connection</font>
-  $db->NewADOConnection('mysql');
-  $db->Connect(...);
-
-  <font color="#006600"># Then create a data dictionary object, using this connection</font>
-  $dict = <strong>NewDataDictionary</strong>($db);
-
-  <font color="#006600"># We have a portable declarative data dictionary format in ADOdb, similar to SQL.
-  # Field types use 1 character codes, and fields are separated by commas.
-  # The following example creates three fields: "col1", "col2" and "col3":</font>
-  $flds = " 
-  <font color="#663300"><strong> col1 C(32) NOTNULL DEFAULT 'abc',
-   col2 I  DEFAULT 0,
-   col3 N(12.2)</strong></font>
-  ";
-
-  <font color="#006600"># We demonstrate creating tables and indexes</font>
-  $sqlarray = $dict-><strong>CreateTableSQL</strong>($tabname, $flds, $taboptarray);
-  $dict-><strong>ExecuteSQLArray</strong>($sqlarray);<br>
-  $idxflds = 'co11, col2';
-  $sqlarray = $dict-><strong>CreateIndexSQL</strong>($idxname, $tabname, $idxflds);
-  $dict-><strong>ExecuteSQLArray</strong>($sqlarray);
-</pre>
-
-<h3>Functions</h3>
-
-<h4>function CreateDatabase($dbname, $optionsarray=false)</h4>
-<p>Create a database with the name $dbname;</p>
-
-<h4>function CreateTableSQL($tabname, $fldarray, $taboptarray=false)</h4>
-<pre>
-  RETURNS:      an array of strings, the sql to be executed, or false
-  $tabname:     name of table
-  $fldarray:    string (or array) containing field info
-  $taboptarray: array containing table options
-</pre>
-<p>The new format of $fldarray uses a free text format, where each field is comma-delimited.
-The first token for each field is the field name, followed by the type and optional
-field size. Then optional keywords in $otheroptions:</p>
-<pre>  "$fieldname $type $colsize $otheroptions"</pre>
-<p>The older (and still supported) format of $fldarray is a 2-dimensional array, where each row in the 1st dimension represents one field. Each row has this format:</p>
-<pre>  array($fieldname, $type, [,$colsize] [,$otheroptions]*)</pre>
-
-<p>The first 2 fields must be the field name and the field type. The field type can be a portable type codes or the actual type for that database.</p>
-<p>Legal portable type codes include:</p>
-<pre>
-  C:  varchar
-  X:  Largest varchar size 
-  XL: For Oracle, returns CLOB, otherwise same as 'X' above
-
-  C2: Multibyte varchar
-  X2: Multibyte varchar (largest size)
-
-  B:  BLOB (binary large object)
-
-  D:  Date (some databases do not support this, and we return a datetime type)
-  T:  Datetime or Timestamp
-  L:  Integer field suitable for storing booleans (0 or 1)
-  I:  Integer (mapped to I4)
-  I1: 1-byte integer
-  I2: 2-byte integer
-  I4: 4-byte integer
-  I8: 8-byte integer
-  F:  Floating point number
-  N:  Numeric or decimal number
-</pre>
-<p>The $colsize field represents the size of the field. If a decimal number is used, then it is assumed that the number following the dot is the precision, so 6.2 means a number of size 6 digits and 2 decimal places. It is recommended that the default for number types be represented as a string to avoid any rounding errors.</p>
-<p>The $otheroptions include the following keywords (case-insensitive):</p>
-<pre>
-  AUTO            For autoincrement number. Emulated with triggers if not available.
-                  Sets NOTNULL also.
-  AUTOINCREMENT   Same as auto.
-  KEY             Primary key field. Sets NOTNULL also. Compound keys are supported.
-  PRIMARY         Same as KEY.
-  DEF             Synonym for DEFAULT for lazy typists.
-  DEFAULT         The default value. Character strings are auto-quoted unless
-                  the string begins and ends with spaces, eg ' SYSDATE '.
-  NOTNULL         If field is not null.
-  DEFDATE         Set default value to call function to get today's date.
-  DEFTIMESTAMP    Set default to call function to get today's datetime.
-  NOQUOTE         Prevents autoquoting of default string values.
-  CONSTRAINTS     Additional constraints defined at the end of the field
-                  definition.
-</pre>
-<p>The Data Dictonary accepts two formats, the older array specification:</p>
-<pre>
-  $flds = array(
-    array('COLNAME',   'DECIMAL', '8.4', 'DEFAULT' => 0, 'NOTNULL'),
-    array('id',        'I'      , 'AUTO'),
-    array('`MY DATE`', 'D'      , 'DEFDATE'),
-    array('NAME',      'C'      , '32', 'CONSTRAINTS' => 'FOREIGN KEY REFERENCES reftable')
-  );
-</pre>
-<p>Or the simpler declarative format:</p>
-<pre>
-  $flds = "<font color="#660000"><strong>
-    COLNAME DECIMAL(8.4) DEFAULT 0 NOTNULL,
-    id I AUTO,
-    `MY DATE` D DEFDATE,
-    NAME C(32) CONSTRAINTS 'FOREIGN KEY REFERENCES reftable'</strong></font>
-  ";
-</pre>
-<p>Note that if you have special characters in the field name (e.g. My Date), you should enclose it in back-quotes. Normally field names are not case-sensitive, but if you enclose it in back-quotes, some databases treat the names as case-sensitive, and some don't. So be careful.</p>
-
-<p>The $taboptarray is the 3rd parameter of the CreateTableSQL function. This contains table specific settings. Legal keywords include:</p>
-<ul>
-  <li><b>REPLACE</b><br />
-    Indicates that the previous table definition should be removed (dropped)together with ALL data. See first example below.
-  </li>
-  <li><b>DROP</b><br />
-    Drop table. Useful for removing unused tables.
-  </li>
-  <li><b>CONSTRAINTS</b><br />
-    Define this as the key, with the constraint as the value. See the postgresql example below.
-    Additional constraints defined for the whole table. You will probably need to prefix this with a comma.
-  </li>
-</ul>
-
-<p>Database specific table options can be defined also using the name of the database type as the array key. In the following example, <em>create the table as ISAM with MySQL, and store the table in the &quot;users&quot; tablespace if using Oracle</em>. And because we specified REPLACE, drop the table first.</p>
-<pre>  $taboptarray = array('mysql' => 'TYPE=ISAM', 'oci8' => 'tablespace users', 'REPLACE');</pre>
-
-<p>You can also define foreignkey constraints. The following is syntax for postgresql:
-<pre>  $taboptarray = array('constraints' => ', FOREIGN KEY (col1) REFERENCES reftable (refcol)');</pre>
-
-<h4>function DropTableSQL($tabname)</h4>
-<p>Returns the SQL to drop the specified table.</p>
-
-<h4>function ChangeTableSQL($tabname, $flds)</h4>
-<p>Checks to see if table exists, if table does not exist, behaves like CreateTableSQL. 
-  If table exists, generates appropriate ALTER TABLE MODIFY COLUMN commands if 
-  field already exists, or ALTER TABLE ADD $column if field does not exist.</p>
-<p>The class must be connected to the database for ChangeTableSQL to detect the 
-  existence of the table. Idea and code contributed by Florian Buzin.</p>
-
-<h4>function CreateIndexSQL($idxname, $tabname, $flds, $idxoptarray=false)</h4>
-<pre>
-  RETURNS:      an array of strings, the sql to be executed, or false
-  $idxname:     name of index
-  $tabname:     name of table
-  $flds:        list of fields as a comma delimited string or an array of strings
-  $idxoptarray: array of index creation options
-</pre>
-<p>$idxoptarray is similar to $taboptarray in that index specific information can be embedded in the array. Other options include:</p>
-<pre>
-  CLUSTERED     Create clustered index (only mssql)
-  BITMAP        Create bitmap index (only oci8)
-  UNIQUE        Make unique index
-  FULLTEXT      Make fulltext index (only mysql)
-  HASH          Create hash index (only postgres)
-  DROP          Drop legacy index
-</pre>
-
-<h4>function DropIndexSQL ($idxname, $tabname = NULL)</h4>
-<p>Returns the SQL to drop the specified index.</p>
-
-<h4>function AddColumnSQL($tabname, $flds)</h4>
-<p>Add one or more columns. Not guaranteed to work under all situations.</p>
-
-<h4>function AlterColumnSQL($tabname, $flds)</h4>
-<p>Warning, not all databases support this feature.</p>
-
-<h4>function DropColumnSQL($tabname, $flds)</h4>
-<p>Drop 1 or more columns.</p>
-
-<h4>function SetSchema($schema)</h4>
-<p>Set the schema.</p>
-
-<h4>function &amp;MetaTables()</h4>
-<h4>function &amp;MetaColumns($tab, $upper=true, $schema=false)</h4>
-<h4>function &amp;MetaPrimaryKeys($tab,$owner=false,$intkey=false)</h4>
-<h4>function &amp;MetaIndexes($table, $primary = false, $owner = false)</h4>
-<p>These functions are wrappers for the corresponding functions in the connection object.  However, the table names will be autoquoted by the TableName function (see below) before being passed to the connection object.</p>
-
-<h4>function NameQuote($name = NULL)</h4>
-<p>If the provided name is quoted with backquotes (`) or contains special characters, returns the name quoted with the appropriate quote character, otherwise the name is returned unchanged.</p>
-
-<h4>function TableName($name)</h4>
-<p>The same as NameQuote, but will prepend the current schema if specified</p>
-
-<h4>function MetaType($t,$len=-1,$fieldobj=false)</h4>
-<h4>function ActualType($meta)</h4>
-<p>Convert between database-independent 'Meta' and database-specific 'Actual' type codes.</p>
-
-<h4>function ExecuteSQLArray($sqlarray, $contOnError = true)</h4>
-<pre>
-  RETURNS:      0 if failed, 1 if executed all but with errors, 2 if executed successfully
-  $sqlarray:    an array of strings with sql code (no semicolon at the end of string)
-  $contOnError: if true, then continue executing even if error occurs
-</pre>
-<p>Executes an array of SQL strings returned by CreateTableSQL or CreateIndexSQL.</p>

-<h2>ADOdb XML Schema (AXMLS)</h2>
-<p>This is a class contributed by Richard Tango-Lowy and Dan Cech that allows the user to quickly
-and easily build a database using the excellent ADODB database library and a simple XML formatted file.
-You can <a href=http://sourceforge.net/projects/adodb-xmlschema/>download the latest version of AXMLS here</a>.</p>
-
-<h3>Quick Start</h3>
-<p>First, create an XML database schema. Let's call it "schema.xml:"</p>
-<pre>
-  &lt;?xml version="1.0"?&gt;
-  &lt;schema version=&quot;0.2&quot;&gt;
-    &lt;table name="mytable"&gt;
-      &lt;field name="row1" type="I"&gt;
-        &lt;descr&gt;An integer row that's a primary key and autoincrements&lt;/descr&gt;
-        &lt;KEY/&gt;
-        &lt;AUTOINCREMENT/&gt;
-      &lt;/field&gt;
-      &lt;field name="row2" type="C" size="16"&gt;
-        &lt;descr&gt;A 16 character varchar row that can't be null&lt;/descr&gt;
-        &lt;NOTNULL/&gt;
-      &lt;/field&gt;
-      &lt;index name=&quot;myindex&quot;&gt;
-        &lt;col&gt;row1&lt;/col&gt;
-        &lt;col&gt;row2&lt;/col&gt;
-      &lt;/index&gt;
-    &lt;/table&gt;
-    &lt;sql&gt;
-      &lt;descr&gt;SQL to be executed only on specific platforms&lt;/descr&gt;
-      &lt;query platform="postgres|postgres7"&gt;
-        insert into mytable ( row1, row2 ) values ( 12, 'stuff' )
-      &lt;/query&gt;
-      &lt;query platform="mysql"&gt;
-        insert into mytable ( row1, row2 ) values ( 12, 'different stuff' )
-      &lt;/query&gt;
-    &lt;/sql&gt;
-  &lt;/schema&gt;
-</pre>
-
-<p>Create a new database using the appropriate tool for your platform.<br />
-Executing the following PHP code will create the a <i>mytable</i> and <i>myindex</i>
-in the database and insert one row into <i>mytable</i> if the platform is postgres or mysql.</p>
-
-<pre>
-  include_once('/path/to/adodb.inc.php');
-  include_once('/path/to/adodb-xmlschema.inc.php');
-
-  <font color="#006600">// To build the schema, start by creating a normal ADOdb connection:</font>
-  $db->NewADOConnection( 'mysql' );
-  $db->Connect( ... );
-
-  <font color="#006600">// Create the schema object and build the query array.</font>
-  $schema = new <b>adoSchema</b>( $db );
-
-  <font color="#006600">// Optionally, set a prefix for newly-created tables. In this example
-  // the prefix "myprefix_" will result in a table named "myprefix_tablename".</font>
-  $schema-><b>SetPrefix</b>( 'myprefix_' );
-
-  <font color="#006600">// Build the SQL array</font>
-  $schema-><b>ParseSchema</b>( 'schema.xml' );
-
-  <font color="#006600">// Execute the SQL on the database</font>
-  $result = $schema-><b>ExecuteSchema</b>();
-
-  <font color="#006600">// Finally, clean up after the XML parser
-  // (PHP won't do this for you!)</font>
-  $schema-><b>Destroy</b>();
-</pre>
-
-
-<h3>Using AXMLS in Your 
-			Application</h3>
-	
-	<p>
-There are two steps involved in using 
-				AXMLS in your application: first, 
-				you must create a schema, or XML representation of your 
-				database, and second, you must create the PHP code that will 
-				parse and execute the schema.</p>
-		<p>Let's begin with a schema that describes a typical, if simplistic 
-			user management table for an application.</p>
-		<pre class="listing"><pre>
-&lt;?xml version=&quot;1.0&quot;?&gt;
-&lt;schema version=&quot;0.2&quot;&gt;
-
-  &lt;table name=&quot;users&quot;&gt;
-    &lt;desc&gt;A typical users table for our application.&lt;/desc&gt;
-    &lt;field name=&quot;userId&quot; type=&quot;I&quot;&gt;
-      &lt;descr&gt;A unique ID assigned to each user.&lt;/descr&gt;
-      &lt;KEY/&gt;
-      &lt;AUTOINCREMENT/&gt;
-    &lt;/field&gt;
-    
-    &lt;field name=&quot;userName&quot; type=&quot;C&quot; size=&quot;16&quot;&gt;&lt;NOTNULL/&gt;&lt;/field&gt;
-    
-    &lt;index name=&quot;userName&quot;&gt;
-      &lt;descr&gt;Put a unique index on the user name&lt;/descr&gt;
-      &lt;col&gt;userName&lt;/col&gt;
-      &lt;UNIQUE/&gt;
-    &lt;/index&gt;
-  &lt;/table&gt;
-  
-  &lt;sql&gt;
-    &lt;descr&gt;Insert some data into the users table.&lt;/descr&gt;
-    &lt;query&gt;insert into users (userName) values ( 'admin' )&lt;/query&gt;
-    &lt;query&gt;insert into users (userName) values ( 'Joe' )&lt;/query&gt;
-  &lt;/sql&gt;
-&lt;/schema&gt;			
-</pre></pre>
-		<p>Let's take a detailed look at this schema.</p>
-		<p>The opening &lt;?xml version=&quot;1.0&quot;?&gt; tag is 
-					required by XML. The &lt;schema&gt; tag 
-					tells the parser that the enclosed markup defines an XML 
-					schema. The version=&quot;0.2&quot; attribute sets 
-					<em>the version of the AXMLS DTD used by the XML 
-					schema.</em> <p>All versions of AXMLS prior 
-					to version 1.0 have a schema version of &quot;0.1&quot;. The current 
-					schema version is &quot;0.2&quot;.</p></p>
-				<pre class="listing"><pre>
-&lt;?xml version=&quot;1.0&quot;?&gt;
-&lt;schema version=&quot;0.2&quot;&gt;
-  ...
-&lt;/schema&gt;
-</pre></pre>
-			<p>Next we define one or more tables. A table consists of a 
-					fields (and other objects) enclosed by 
-					&lt;table&gt; tags. The 
-					name=&quot;&quot; attribute specifies the name of 
-					the table that will be created in the database.</p>
-				<pre class="listing"><pre>
-&lt;table name=&quot;users&quot;&gt;
-
-    &lt;desc&gt;A typical users table for our application.&lt;/desc&gt;
-    &lt;field name=&quot;userId&quot; type=&quot;I&quot;&gt;
-      &lt;descr&gt;A unique ID assigned to each user.&lt;/descr&gt;
-      &lt;KEY/&gt;
-      &lt;AUTOINCREMENT/&gt;
-    &lt;/field&gt;
-    
-    &lt;field name=&quot;userName&quot; type=&quot;C&quot; size=&quot;16&quot;&gt;&lt;NOTNULL/&gt;&lt;/field&gt;
-    
-&lt;/table&gt;
-</pre></pre>
-				<p>This table is called &quot;users&quot; and has a description and 
-					two fields. The description is optional, and is currently 
-					only for your own information; it is not applied to the 
-					database.</p>
-				<p>The first &lt;field&gt; tag will create 
-					a field named &quot;userId&quot; of type &quot;I&quot;, or integer. (See the 
-					ADOdb Data Dictionary 
-					documentation for a list of valid types.) This 
-					&lt;field&gt; tag encloses two special 
-					field options: &lt;KEY/&gt;, which 
-					specifies this field as a primary key, and 
-					&lt;AUTOINCREMENT/&gt;, which specifies 
-					that the database engine should automatically fill this 
-					field with the next available value when a new row is 
-					inserted.</p>
-				<p>The second &lt;field&gt; tag will create 
-					a field named &quot;userName&quot; of type &quot;C&quot;, or character, and of 
-					length 16 characters. The &lt;NOTNULL/&gt; 
-					option specifies that this field does not allow 
-					NULLs.</p>
-			<p>There are two ways to add indexes to a table. The 
-					simplest is to mark a field with the 
-					&lt;KEY/&gt; option as described above; a 
-					primary key is a unique index. The second and more powerful 
-					method uses the &lt;index&gt; tags.</p>
-				<pre class="listing"><pre>
-&lt;table name=&quot;users&quot;&gt;
-  ...
-    
-  &lt;index name=&quot;userName&quot;&gt;
-    &lt;descr&gt;Put a unique index on the user name&lt;/descr&gt;
-    &lt;col&gt;userName&lt;/col&gt;
-    &lt;UNIQUE/&gt;
-  &lt;/index&gt;
-    
-&lt;/table&gt;
-</pre></pre>
-				<p>The &lt;index&gt; tag specifies that an 
-					index should be created on the enclosing table. The 
-					name=&quot;&quot; attribute provides the name of the 
-					index that will be created in the database. The 
-					description, as above, is for your information only. The 
-					&lt;col&gt; tags list each column that 
-					will be included in the index. Finally, the 
-					&lt;UNIQUE/&gt; tag specifies that this 
-					will be created as a unique index.</p>
-			<p>Finally, AXMLS allows you to include arbitrary SQL that 
-					will be applied to the database when the schema is 
-					executed.</p>
-				<pre class="listing"><pre>
-&lt;sql&gt;
-  &lt;descr&gt;Insert some data into the users table.&lt;/descr&gt;
-  &lt;query&gt;insert into users (userName) values ( 'admin' )&lt;/query&gt;
-  &lt;query&gt;insert into users (userName) values ( 'Joe' )&lt;/query&gt;
-&lt;/sql&gt;
-</pre></pre>
-				<p>The &lt;sql&gt; tag encloses any number 
-					of SQL queries that you define for your own use.</p>
-		<p>Now that we've defined an XML schema, you need to know how to 
-			apply it to your database. Here's a simple PHP script that shows 
-			how to load the schema.</p>
-		<p><pre class="listing"><pre>
-&lt;?PHP
-/* You must tell the script where to find the ADOdb and
- * the AXMLS libraries.
- */
-require( &quot;path_to_adodb/adodb.inc.php&quot;);
-require( &quot;path_to_adodb/adodb-xmlschema.inc.php&quot; );
-
-/* Configuration information. Define the schema filename,
- * RDBMS platform (see the ADODB documentation for valid
- * platform names), and database connection information here.
- */
-$schemaFile = 'example.xml';
-$platform = 'mysql';
-$dbHost = 'localhost';
-$dbName = 'database';
-$dbUser = 'username';
-$dbPassword = 'password';
-
-/* Start by creating a normal ADODB connection.
- */
-$db = ADONewConnection( $platform );
-$db-&gt;Connect( $dbHost, $dbUser, $dbPassword, $dbName );
-
-/* Use the database connection to create a new adoSchema object.
- */
-$schema = new adoSchema( $db );
-
-/* Call ParseSchema() to build SQL from the XML schema file.
- * Then call ExecuteSchema() to apply the resulting SQL to 
- * the database.
- */
-$sql = $schema-&gt;ParseSchema( $schemaFile );
-$result = $schema-&gt;ExecuteSchema();
-?&gt;
-</pre></pre></p>
-		<p>Let's look at each part of the example in turn. After you 
-			manually create the database, there are three steps required to 
-			load (or upgrade) your schema.</p>
-		<p>First, create a normal ADOdb connection. The variables 
-					and values here should be those required to connect to your 
-					database.</p>
-				<pre class="listing"><pre>
-$db = ADONewConnection( 'mysql' );
-$db-&gt;Connect( 'host', 'user', 'password', 'database' );
-</pre></pre>
-			<p>Second, create the adoSchema object that load and 
-					manipulate your schema. You must pass an ADOdb database 
-					connection object in order to create the adoSchema 
-					object.</p>
-				<pre class="listing"><pre>
-$schema = new adoSchema( $db );
-</pre></pre>
-			<p>Third, call ParseSchema() to parse the 
-					schema and then ExecuteSchema() to apply 
-					it to the database. You must pass 
-					ParseSchema() the path and filename of 
-					your schema file.</p>
-				<pre class="listing"><pre>
-$schema-&gt;ParseSchema( $schemaFile ); 
-$schema-&gt;ExecuteSchema(); 
-</pre></pre>
-		<p>Execute the above code and then log into your database. If you've 
-			done all this right, you should see your tables, indexes, and 
-			SQL.</p>
-		<p>You can find the source files for this tutorial in the 
-			examples directory as 
-			tutorial_shema.xml and 
-			tutorial.php. See the class documentation for 
-			a more detailed description of the adoSchema methods, including 
-			methods and schema elements that are not described in this 
-			tutorial.</p>

-</pre>
-
-<h3>Upgrading</h3>
-If your schema version is older, than XSLT is used to transform the schema to the newest version. 
-This means that if you are using an older XML schema format,  you need to have the XSLT extension installed.
-If you do not want to require your users to have the XSLT extension installed, make sure you 
-modify your XML schema to conform to the latest version.

-</head>
-
-<body>
-<h3>The ADOdb Performance Monitoring Library</h3>
-<p>V4.20 22 Feb 2004 (c) 2000-2004 John Lim (jlim#natsoft.com.my)</p>
-<p><font size="1">This software is dual licensed using BSD-Style and LGPL. This 
-  means you can use it in compiled proprietary and commercial products.</font></p>
-  <p>Useful ADOdb links:  <a href=http://php.weblogs.com/adodb?perf=1>Download</a> &nbsp; <a href=http://php.weblogs.com/adodb_manual?perf=1>Other Docs</a>
-<h3>Introduction</h3>
-<p>This module, part of the ADOdb package, provides both CLI and HTML interfaces 
-  for viewing key performance indicators of your database. This is very useful 
-  because web apps such as the popular phpMyAdmin currently do not provide effective 
-  database health monitoring tools. The module provides the following: 
-<ul>
-  <li>A quick health check of your database server using <code>$perf->HealthCheck()</code> 
-    or <code>$perf->HealthCheckCLI()</code>. 
-  <li>User interface for performance monitoring, <code>$perf-&gt;UI()</code>. 
-    This UI displays: 
-    <ul>
-      <li>the health check, </li>
-      <li>all SQL logged and their query plans, </li>
-      <li>a list of all tables in the current database</li>
-      <li>an interface to continiously poll the server for key performance indicators 
-        such as CPU, Hit Ratio, Disk I/O</li>
-		<li>a form where you can enter and run SQL interactively.</li>
-    </ul>
-  <li>Gives you an API to build database monitoring tools for a server farm, for 
-    example calling <code>$perf->DBParameter('data cache hit ratio')</code> returns 
-    this very important statistic in a database independant manner. 
-</ul>
-<p>ADOdb also has the ability to log all SQL executed, using <a href=docs-adodb.htm#logsql>LogSQL</a>. 
-  All SQL logged can be analyzed through the performance monitor <a href=#ui>UI</a>. 
-  In the <i>View SQL</i> mode, we categorize the SQL into 3 types:
-<ul>
-  <li><b>Suspicious SQL</b>: queries with high average execution times, and are potential 
-    candidates for rewriting</li>
-  <li><b>Expensive SQL</b>: queries with high total execution times (#executions * avg 
-    execution time). Optimizing these queries will reduce your database server 
-    load.</li>
-  <li><b>Invalid SQL</b>: queries that generate errors.</li>
-</ul>
-<p>Each query is hyperlinked to a description of the query plan, and every PHP 
-  script that executed that query is also shown.</p>
-<p>Please note that the information presented is a very basic database health 
-  check, and does not provide a complete overview of database performance. Although 
-  some attempt has been made to make it work across multiple databases in the 
-  same way, it is impossible to do so. For the health check, we do try to display 
-  the following key database parameters for all drivers:</p>
-<ul>
-  <li><b>data cache size</b> - The amount of memory allocated to the cache.</li>
-  <li><b>data cache hit ratio</b> - A measure of how effective the cache is, as a percentage. 
-  The higher, the better.</li>
-  <li><b>current connections</b> - The number of sessions currently connected to the 
-    database. </li>
-</ul>
-<p>You will need to connect to the database as an administrator to view most of 
-  the parameters. </p>
-<p>Code improvements as very welcome, particularly adding new database parameters 
-  and automated tuning hints.</p><a name=usage></a>
-<h3>Usage</h3>
-<p>Currently, the following drivers: <em>mysql</em>, <em>postgres</em>, <em>oci8</em>, 
-  <em>mssql</em>, <i>informix</i> and <em>db2</em> are supported. To create a 
-  new performance monitor, call NewPerfMonitor( ) as demonstrated below: </p>
-<pre>
-&lt;?php
-include_once('adodb.inc.php');
-session_start(); <font color="#006600"># session variables required for monitoring</font>
-$conn = ADONewConnection($driver);
-$conn-&gt;Connect($server,$user,$pwd,$db);
-$perf =&amp; NewPerfMonitor($conn);
-$perf-&gt;UI($pollsecs=5);<font color="#006600"></font>
-?>
-</pre>
-<p>It is also possible to retrieve a single database parameter:</p>
-<pre>$size = $perf->DBParameter('data cache size');
-</pre>
-<p>
-Thx to Fernando Ortiz for the informix module. 
-<h3>Methods</h3><a name=ui></a>
-<p><font face="Courier New, Courier, mono">function <b>UI($pollsecs=5)</b></font></p>
-<p>Creates a web-based user interface for performance monitoring. When you click on Poll, 
-server statistics will be displayed every $pollsecs seconds.  See <a href="#usage">Usage</a> 
-  above. 
-  <p>Since 4.11, we allow users to enter and run SQL interactively via the "Run SQL" link. To disable
-  this for security reasons, set this constant before calling $perf->UI().

-<p><b>WS-CPU%</b> is the Web Server CPU load of the server that PHP is running 
-  from (eg. the database client), and not the database. The <b>Hit%</b> is the 
-  data cache hit ratio. <b>Sess</b> is the current number of sessions connected 
-  to the database. If you are using persistent connections, this should not change 
-  much. The <b>Reads/s</b> and <b>Writes/s</b> are synthetic values to give the 
-  viewer a rough guide to I/O, and are not to be taken literally. 
-<p><font face="Courier New, Courier, mono">function <b>SuspiciousSQL</b>($numsql=10)</font></p>
-<p>Returns SQL which have high average execution times as a HTML table. Each sql statement
-is hyperlinked to a new window which details the execution plan and the scripts that execute this SQL.
-<p> The number of statements returned is determined by $numsql. Data is taken from the adodb_logsql table, where the sql statements are logged when
-$connection->LogSQL(true) is enabled. The adodb_logsql table is populated using <a href=docs-adodb.htm#logsql>$conn->LogSQL</a>.
-<p>For Oracle, Ixora Suspicious SQL returns a list of SQL statements that are most cache intensive as a HTML table. 
-  These are data intensive SQL statements that could benefit most from tuning. 
- 
-<p><font face="Courier New, Courier, mono">function <b>ExpensiveSQL</b>($numsql=10)</font></p>
-<p>Returns SQL whose total execution time (avg time * #executions) is high as a HTML table. Each sql statement
-is hyperlinked to a new window which details the execution plan and the scripts that execute this SQL.
-<p> The number of statements returned is determined by $numsql. Data is taken from the adodb_logsql table, where the sql statements are logged when
-$connection->LogSQL(true) is enabled. The adodb_logsql table is populated using <a href=docs-adodb.htm#logsql>$conn->LogSQL</a>.
-
-<p>For Oracle, Ixora Expensive SQL returns a list of SQL statements that are taking the most CPU load 
-when run.
-<p><font face="Courier New, Courier, mono">function <b>InvalidSQL</b>($numsql=10)</font></p>
-<p>Returns a list of invalid SQL as an HTML table.
-<p>Data is taken from the adodb_logsql table, where the sql statements are logged when
-$connection->LogSQL(true) is enabled.
-<p><font face="Courier New, Courier, mono">function <b>Tables</b>($orderby=1)</font></p>
-<p>Returns information on all tables in a database, with the first two fields 
-  containing the table name and table size, the remaining fields depend on the 
-  database driver. If $orderby is set to 1, it will sort by name. If $orderby 
-  is set to 2, then it will sort by table size. Some database drivers (mssql and 
-  mysql) will ignore the $orderby clause. For postgresql, the information is up-to-date 
-  since the last <i>vacuum</i>. Not supported currently for db2.</p>
-<h3>Raw Functions</h3>
-<p>Raw functions return values without any formatting.</p>
-<p><font face="Courier New, Courier, mono">function <b>DBParameter</b>($paramname)</font></p>
-<p>Returns the value of a database parameter, such as $this-&gt;DBParameter(&quot;data 
-  cache size&quot;).</p>
-<p><font face="Courier New, Courier, mono">function <b>CPULoad</b>()</font></p>
-<p>Returns the CPU load of the database client (NOT THE SERVER) as a percentage. 
-  Only works for Linux and Windows. For Windows, WMI must be available.</p>
-<h3>Format of $settings Property</h3>
-<p> To create new database parameters, you need to understand $settings. The $settings 
-  data structure is an associative array. Each element of the array defines a 
-  database parameter. The key is the name of the database parameter. If no key is defined,
-  then it is assumed to be a section break, and the value is the name of the section break.
-  If this is too confusing, looking at the source code will help a lot!</p>
-<p> Each database parameter is itself an array consisting of the following elements:</p>
-<ol start="0">
-  <li> Category code, used to group related db parameters. If the category code is 'HIDE', then
-the database parameter is not shown when HTML() is called. <br>
-  </li>
-  <li> either 
-    <ol type="a">
-      <li>sql string to retrieve value, eg. "select value from v\$parameter where 
-        name='db_block_size'", </li>
-      <li>array holding sql string and field to look for, e.g. array('show variables','table_cache'); 
-        optional 3rd parameter is the $rs-&gt;fields[$index] to use (otherwise 
-        $index=1), and optional 4th parameter is a constant to multiply the result 
-        with (typically 100 for percentage calculations),</li>
-      <li>a string prefixed by =, then a PHP method of the class is invoked, e.g. 
-        to invoke $this->GetIndexValue(), set this array element to '=GetIndexValue', 
-        <br>
-      </li>
-    </ol>
-  </li>
-  <li> Description of database parameter. If description begins with an =, then 
-    it is interpreted as a method call, just as in (1c) above, taking one parameter, 
-    the current value. E.g. '=GetIndexDescription' will invoke $this->GetIndexDescription($val). 
-    This is useful for generating tuning suggestions. For an example, see WarnCacheRatio().</li>
-</ol>
-<p>Example from MySQL, table_cache database parameter:</p>
-<pre>'table cache' =&gt; array('CACHE',            # category code
-   array(&quot;show variables&quot;, 'table_cache'), # array (type 1b)
-   'Number of tables to keep open'),       # description</pre>

-<h3>Introduction</h3>
-<p> 
-We store state information specific to a user or web client in session variables. These session variables 
- persist throughout a session, as the user moves from page to page. 
-<p>
-To use session variables, call session_start() at the beginning of your web page, 
-before your HTTP headers are sent. Then for every variable you want to keep alive 
-for the duration of the session, call session_register($variable_name). By default, 
-the session handler will keep track of the session by using a cookie. You can save objects
- or arrays in session variables also.
-<p>The default method of storing sessions is to store it in a file. However if 
-  you have special needs such as you:
-<ul>
-  <li>Have multiple web servers that need to share session info</li>
-  <li>Need to do special processing of each session</li>
-  <li>Require notification when a session expires</li>
-</ul>
-<p>Then the ADOdb session handler provides you with the above additional capabilities 
-  by storing the session information as records in a database table that can be 
-  shared across multiple servers. 
-<p><b>Important Upgrade Notice:</b> Since ADOdb 4.05, the session files have been moved to its own folder, adodb/session. This is a rewrite
-of the session code by Ross Smith. The old session code is in adodb/session/old. 
-<h4>ADOdb Session Handler Features</h4>
-<ul>
-<li>Ability to define a notification function that is called when a session expires. Typically
-used to detect session logout and release global resources.
-<li>Optimization of database writes. We crc32 the session data and only perform an update
-to the session data if there is a data change.
-<li>Support for large amounts of session data with CLOBs (see adodb-session-clob.php). Useful
-for Oracle.
-<li>Support for encrypted session data, see adodb-cryptsession.inc.php. Enabling encryption 
-is simply a matter of including adodb-cryptsession.inc.php instead of adodb-session.inc.php.
-</ul>
-<h3>Setup</h3>
-<p>There are 3 session management files that you can use:
-<pre>
-adodb-session.php        : The default
-adodb-session-clob.php   : Use this if you are storing DATA in clobs
-adodb-cryptsession.php   : Use this if you want to store encrypted session data in the database
-
-<strong>Examples</strong>
- <font color=#004040>
-    include('adodb/adodb.inc.php');
-    
-<b>    $ADODB_SESSION_DRIVER='mysql';
-    $ADODB_SESSION_CONNECT='localhost';
-    $ADODB_SESSION_USER ='scott';
-    $ADODB_SESSION_PWD ='tiger';
-    $ADODB_SESSION_DB ='sessiondb';</b>
-    
-    <b>include('adodb/session/adodb-session.php');</b>
-    session_start();
-    
-    #
-    # Test session vars, the following should increment on refresh
-    #
-    $_SESSION['AVAR'] += 1;
-    print "&lt;p>\$_SESSION['AVAR']={$_SESSION['AVAR']}&lt;/p>";
-</font>
-To force non-persistent connections, call adodb_session_open first before session_start():
- <font color=#004040>
-    include('adodb/adodb.inc.php');
-    
-<b>    $ADODB_SESSION_DRIVER='mysql';
-    $ADODB_SESSION_CONNECT='localhost';
-    $ADODB_SESSION_USER ='scott';
-    $ADODB_SESSION_PWD ='tiger';
-    $ADODB_SESSION_DB ='sessiondb';</b>
-    
-    <b>include('adodb/session/adodb-session.php');
-    adodb_sess_open(false,false,false);</b>
-    session_start();
- </font color=#004040>
-To use a encrypted sessions, simply replace the file:
- <font color=#004040>
-    include('adodb/adodb.inc.php');
-    
-<b>    $ADODB_SESSION_DRIVER='mysql';
-    $ADODB_SESSION_CONNECT='localhost';
-    $ADODB_SESSION_USER ='scott';
-    $ADODB_SESSION_PWD ='tiger';
-    $ADODB_SESSION_DB ='sessiondb';
-    
-    include('adodb/session/adodb-cryptsession.php');</b>
-    session_start();
-    </font>
-And the same technique for adodb-session-clob.php:
- <font color=#004040>
-    include('adodb/adodb.inc.php');
-    
-<b>    $ADODB_SESSION_DRIVER='mysql';
-    $ADODB_SESSION_CONNECT='localhost';
-    $ADODB_SESSION_USER ='scott';
-    $ADODB_SESSION_PWD ='tiger';
-    $ADODB_SESSION_DB ='sessiondb';
-    
-    include('adodb/session/adodb-session-clob.php');</b>
-    session_start();
-    </font>
- <h4>Installation</h4>
- 1. Create this table in your database (syntax might vary depending on your db):
- <a name=sessiontab></a> <font color=#004040>
-  create table sessions (
-       SESSKEY char(32) not null,
-       EXPIRY int(11) unsigned not null,
-       EXPIREREF varchar(64),
-       DATA text not null,
-      primary key (sesskey)
-  );</font>
-  
-  For the adodb-session-clob.php version, create this:
-   <font color=#004040>
-    create table sessions (
-       SESSKEY char(32) not null,
-       EXPIRY int(11) unsigned not null,
-       EXPIREREF varchar(64),
-       DATA CLOB,
-      primary key (sesskey)
-  );</font>
-
-  2. Then define the following parameters. You can either modify
-     this file, or define them before this file is included:
-      <font color=#004040>
-    $ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
-    $ADODB_SESSION_CONNECT='server to connect to';
-    $ADODB_SESSION_USER ='user';
-    $ADODB_SESSION_PWD ='password';
-    $ADODB_SESSION_DB ='database';
-    $ADODB_SESSION_TBL = 'sessions'; # setting this is optional
-	</font>
-    When the session is created, $<b>ADODB_SESS_CONN</b> holds the connection object.
-    
-  3. Recommended is PHP 4.0.6 or later. There are documented session bugs 
-  in earlier versions of PHP.
-</pre>
-
-    <h3>Notifications</h3>
-<p>If you want to receive notification when a session expires, then
-     tag the session record with a <a href="#sessiontab">EXPIREREF</a> tag (see the 
-    definition of the sessions table above).  Before any session record is deleted,
-	ADOdb will call a notification function, passing in the EXPIREREF.
-<p>
-When a session is first created, we check a global variable $ADODB_SESSION_EXPIRE_NOTIFY.
-    This is an array with 2 elements, the first being the name of the session variable
-    you would like to store in the EXPIREREF field, and the 2nd is the 
-    notification function's name.
-	<p>
-	 Suppose we want to be notified when a user's session 
-    has expired, based on the userid. The user id in the global session variable $USERID.
-	The function name is 'NotifyFn'. So we define:
-    <pre> <font color=#004040>
-        $ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
-    </font></pre>
-    And when the NotifyFn is called (when the session expires), we pass the $USERID 
-    as the first parameter, eg. NotifyFn($userid, $sesskey). The session key (which is 
-	the primary key of the record in the sessions table) is the 2nd parameter.
-  <p>
-    Here is an example of a Notification function that deletes some records in the database
-	and temporary files:
-    <pre><font color=#004040>
-        function NotifyFn($expireref, $sesskey)
-        {
-        global $ADODB_SESS_CONN; # the session connection object

-    <p>
-    NOTE: If you want to change the EXPIREREF after the session record has been
-    created, you will need to modify any session variable to force a database
-    record update.
-<h4>Compression/Encryption Schemes</h4>
-Since ADOdb 4.05, thanks to Ross Smith,  multiple encryption and compression schemes are supported.
-  Currently, supported:
-<pre>
-  MD5Crypt (crypt.inc.php)
-  MCrypt
-  Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)
-  GZip
-  BZip2
-</pre>
-These are stackable. E.g. 
-<pre>
-ADODB_Session::filter(new ADODB_Compress_Bzip2());
-ADODB_Session::filter(new ADODB_Encrypt_MD5());
-</pre>
-will compress and then encrypt the record in the database.
-<p>
-Also see the <a href=docs-adodb.htm>core ADOdb documentation</a>.

-OK, I hacked out an ADOdb container for PEAR-Auth. The error handling's 
-a bit of a mess, but all the methods work.
-
-Copy ADOdb.php to your pear/Auth/Container/ directory.
-
-Use the ADOdb container exactly as you would the DB
-container, but specify 'ADOdb' instead of 'DB':
-
-$dsn = "mysql://myuser:mypass@localhost/authdb";
-$a = new Auth("ADOdb", $dsn, "loginFunction");
-

-<h3>ADOdb Library for PHP</h3>
-<p>ADOdb is a suite of database libraries that allow you to connect to multiple 
-	databases in a portable manner. Download from <a href=http://php.weblogs.com/adodb>http://php.weblogs.com/adodb</a>.
-<ul><li>The ADOdb documentation has moved to <a href=docs-adodb.htm>docs-adodb.htm</a> 
-	This allows you to query, update and insert records using a portable API.
-<p><li>The ADOdb data dictionary docs are at <a href=docs-datadict.htm>docs-datadict.htm</a>. 
-	This allows you to create database tables and indexes in a portable manner.
-<p><li>The ADOdb database performance monitoring docs are at <a href=docs-perf.htm>docs-perf.htm</a>. 
-	This allows you to perform health checks, tune and monitor your database.
-<p><li>The ADOdb database-backed session docs are at <a href=docs-session.htm>docs-session.htm</a>. 
-</ul>
-<p>
-<h3>Installation</h3>
-Make sure you are running PHP4.0.4 or later. Unpack all the files into a directory accessible by your webserver.
-<p>
-To test, try modifying some of the tutorial examples. Make sure you customize the connection settings correctly. You can debug using:
-<pre>
-&lt;?php
-include('adodb/adodb.inc.php');
-
-$db = <b>ADONewConnection</b>($driver); # eg. 'mysql' or 'oci8' 
-$db->debug = true;
-$db-><b>Connect</b>($server, $user, $password, $database);
-$rs = $db-><b>Execute</b>('select * from some_small_table');
-print "&lt;pre>";
-print_r($rs-><b>GetRows</b>());
-print "&lt;/pre>";
-?>
-</pre>
-<h3>How are people using ADOdb</h3>

-  <p>Updated 18 Sep 2003. Added Portable Native SQL section.
-<p>
-
- If you are writing an application that is used in multiple environments and 
-  operating systems, you need to plan to support multiple databases. This article 
-  is based on my experiences with multiple database systems, stretching from 4th 
-  Dimension in my Mac days, to the databases I currently use, which are: Oracle, 
-  FoxPro, Access, MS SQL Server and MySQL. Although most of the advice here applies 
-  to using SQL with Perl, Python and other programming languages, I will focus on PHP and how 
-  the <a href="http://php.weblogs.com/adodb">ADOdb</a> database abstraction library 
-  offers some solutions.<p></p>
-<p>Most database vendors practice product lock-in. The best or fastest way to 
-  do things is often implemented using proprietary extensions to SQL. This makes 
-  it extremely hard to write portable SQL code that performs well under all conditions. 
-  When the first ANSI committee got together in 1984 to standardize SQL, the database 
-  vendors had such different implementations that they could only agree on the 
-  core functionality of SQL. Many important application specific requirements 
-  were not standardized, and after so many years since the ANSI effort began, 
-  it looks as if much useful database functionality will never be standardized. 
-  Even though ANSI-92 SQL has codified much more, we still have to implement portability 
-  at the application level.</p>
-<h3><b>Selects</b></h3>
-<p>The SELECT statement has been standardized to a great degree. Nearly every 
-  database supports the following:</p>
-<p>SELECT [cols] FROM [tables]<br>
-  &nbsp;&nbsp;[WHERE conditions]<br>
-  &nbsp; [GROUP BY cols]<br>
-  &nbsp; [HAVING conditions] <br>
-  &nbsp; [ORDER BY cols]</p>
-<p>But so many useful techniques can only be implemented by using proprietary 
-  extensions. For example, when writing SQL to retrieve the first 10 rows for 
-  paging, you could write...</p>
-<table width="80%" border="1" cellspacing="0" cellpadding="0" align="center">
-  <tr> 
-	<td><b>Database</b></td>
-	<td><b>SQL Syntax</b></td>
-  </tr>
-  <tr> 
-	<td>DB2</td>
-	<td>select * from table fetch first 10 rows only</td>
-  </tr>
-  <tr> 
-	<td>Informix</td>
-	<td>select first 10 * from table</td>
-  </tr>
-  <tr> 
-	<td>Microsoft SQL Server and Access</td>
-	<td>select top 10 * from table</td>
-  </tr>
-  <tr> 
-	<td>MySQL and PostgreSQL</td>
-	<td>select * from table limit 10</td>
-  </tr>
-  <tr> 
-	<td>Oracle 8i</td>
-	<td>select * from (select * from table) where rownum &lt;= 10</td>
-  </tr>
-</table>
-<p>This feature of getting a subset of data is so useful that in the PHP class 
-  library ADOdb, we have a SelectLimit( ) function that allows you to hide the 
-  implementation details within a function that will rewrite your SQL for you:</p>
-<pre>$connection-&gt;SelectLimit('select * from table', 10);
-</pre>
-<p><b>Selects: Fetch Modes</b></p>
-<p>PHP allows you to retrieve database records as arrays. You can choose to have 
-  the arrays indexed by field name or number. However different low-level PHP 
-  database drivers are inconsistent in their indexing efforts. ADOdb allows you 
-  to determine your prefered mode. You set this by setting the variable $ADODB_FETCH_MODE 
-  to either of the constants ADODB_FETCH_NUM (for numeric indexes) or ADODB_FETCH_ASSOC 
-  (using field names as an associative index).</p>
-<p>The default behaviour of ADOdb varies depending on the database you are using. 
-  For consistency, set the fetch mode to either ADODB_FETCH_NUM (for speed) or 
-  ADODB_FETCH_ASSOC (for convenience) at the beginning of your code. </p>
-<p><b>Selects: Counting Records</b></p>
-<p>Another problem with SELECTs is that some databases do not return the number 
-  of rows retrieved from a select statement. This is because the highest performance 
-  databases will return records to you even before the last record has been found. 
-</p>
-<p>In ADOdb, RecordCount( ) returns the number of rows returned, or will emulate 
-  it by buffering the rows and returning the count after all rows have been returned. 
-  This can be disabled for performance reasons when retrieving large recordsets 
-  by setting the global variable $ADODB_COUNTRECS = false. This variable is checked 
-  every time a query is executed, so you can selectively choose which recordsets 
-  to count.</p>
-<p>If you prefer to set $ADODB_COUNTRECS = false, ADOdb still has the PO_RecordCount( 
-  ) function. This will return the number of rows, or if it is not found, it will 
-  return an estimate using SELECT COUNT(*):</p>
-<pre>$rs = $db-&gt;Execute(&quot;select * from table where state=$state&quot;);
-$numrows = $rs-&gt;PO_RecordCount('table', &quot;state=$state&quot;);</pre>
-<p><b>Selects: Locking</b> </p>
-<p>SELECT statements are commonly used to implement row-level locking of tables. 
-  Other databases such as Oracle, Interbase, PostgreSQL and MySQL with InnoDB 
-  do not require row-level locking because they use versioning to display data 
-  consistent with a specific point in time.</p>
-<p>Currently, I recommend encapsulating the row-level locking in a separate function, 
-  such as RowLock($table, $where):</p>
-<pre>$connection-&gt;BeginTrans( );
-$connection-&gt;RowLock($table, $where); </pre>
-<pre><font color=green># some operation</font></pre>
-<pre>if ($ok) $connection-&gt;CommitTrans( );
-else $connection-&gt;RollbackTrans( );
-</pre>
-<p><b>Selects: Outer Joins</b></p>
-<p>Not all databases support outer joins. Furthermore the syntax for outer joins 
-  differs dramatically between database vendors. One portable (and possibly slower) 
-  method of implementing outer joins is using UNION.</p>
-<p>For example, an ANSI-92 left outer join between two tables t1 and t2 could 
-  look like:</p>
-<pre>SELECT t1.col1, t1.col2, t2.cola <br>  FROM t1 <i>LEFT JOIN</i> t2 ON t1.col = t2.col</pre>
-<p>This can be emulated using:</p>
-<pre>SELECT t1.col1, t1.col2, t2.cola FROM t1, t2 <br>	   WHERE t1.col = t2.col 
-   UNION ALL
-SELECT col1, col2, null FROM t1 <br>	   WHERE t1.col not in (select distinct col from t2)
-</pre>
-<p>Since ADOdb 2.13, we provide some hints in the connection object as to legal 
-  join variations. This is still incomplete and sometimes depends on the database 
-  version you are using, but is useful as a general guideline:</p>
-<p><font face="Courier New, Courier, mono">$conn-&gt;leftOuter</font>: holds the 
-  operator used for left outer joins (eg. '*='), or false if not known or not 
-  available.<br>
-  <font face="Courier New, Courier, mono">$conn-&gt;rightOuter</font>: holds the 
-  operator used for right outer joins (eg '=*'), or false if not known or not 
-  available.<br>
-  <font face="Courier New, Courier, mono">$conn-&gt;ansiOuter</font>: boolean 
-  that if true means that ANSI-92 style outer joins are supported, or false if 
-  not known.</p>
-<h3><b>Inserts</b> </h3>
-<p>When you create records, you need to generate unique id's for each record. 
-  There are two common techniques: (1) auto-incrementing columns and (2) sequences. 
-</p>
-<p>Auto-incrementing columns are supported by MySQL, Sybase and Microsoft Access 
-  and SQL Server. However most other databases do not support this feature. So 
-  for portability, you have little choice but to use sequences. Sequences are 
-  special functions that return a unique incrementing number every time you call 
-  it, suitable to be used as database keys. In ADOdb, we use the GenID( ) function. 
-  It has takes a parameter, the sequence name. Different tables can have different 
-  sequences. </p>
-<pre>$id = $connection-&gt;GenID('sequence_name');<br>$connection-&gt;Execute(&quot;insert into table (id, firstname, lastname) <br>			   values ($id, $firstname, $lastname)&quot;);</pre>
-<p>For databases that do not support sequences natively, ADOdb emulates sequences 
-  by creating a table for every sequence.</p>
-<h3><b>Binding</b></h3>
-<p>Binding variables in an SQL statement is another tricky feature. Binding is 
-  useful because it allows pre-compilation of SQL. When inserting multiple records 
-  into a database in a loop, binding can offer a 50% (or greater) speedup. However 
-  many databases such as Access and MySQL do not support binding natively and 
-  there is some overhead in emulating binding. Furthermore, different databases 
-  (specificly Oracle!) implement binding differently. My recommendation is to 
-  use binding if your database queries are too slow, but make sure you are using 
-  a database that supports it like Oracle. </p>
-<p>ADOdb supports portable Prepare/Execute with:</p>
-<pre>$stmt = $db-&gt;Prepare('select * from customers where custid=? and state=?');
-$rs = $db-&gt;Execute($stmt, array($id,'New York'));</pre>
-<p>Oracle uses named bind placeholders, not "?", so to support portable binding, we have Param() that generates 
-the correct placeholder (available since ADOdb 3.92):
-<pre><font color="#000000">$sql = <font color="#993300">'insert into table (col1,col2) values ('</font>.$DB-&gt;Param('a').<font color="#993300">','</font>.$DB-&gt;Param('b').<font color="#993300">')'</font>;
-<font color="#006600"># generates 'insert into table (col1,col2) values (?,?)'
-# or        'insert into table (col1,col2) values (:a,:b)</font>'
-$stmt = $DB-&gt;Prepare($sql);
-$stmt = $DB-&gt;Execute($stmt,array('one','two'));
-</font></pre>
-<a name="native"></a>
-<h2>Portable Native SQL</h2>
-<p>ADOdb provides the following functions for portably generating SQL functions 
-  as strings to be merged into your SQL statements (some are only available since 
-  ADOdb 3.92): </p>
-<table width="75%" border="1" align=center>
-  <tr> 
-    <td width=30%><b>Function</b></td>
-    <td><b>Description</b></td>
-  </tr>
-  <tr> 
-    <td>DBDate($date)</td>
-    <td>Pass in a UNIX timestamp or ISO date and it will convert it to a date 
-      string formatted for INSERT/UPDATE</td>
-  </tr>
-  <tr> 
-    <td>DBTimeStamp($date)</td>
-    <td>Pass in a UNIX timestamp or ISO date and it will convert it to a timestamp 
-      string formatted for INSERT/UPDATE</td>
-  </tr>
-  <tr> 
-    <td>SQLDate($date, $fmt)</td>
-    <td>Portably generate a date formatted using $fmt mask, for use in SELECT 
-      statements.</td>
-  </tr>
-  <tr> 
-    <td>OffsetDate($date, $ndays)</td>
-    <td>Portably generate a $date offset by $ndays.</td>
-  </tr>
-  <tr> 
-    <td>Concat($s1, $s2, ...)</td>
-    <td>Portably concatenate strings. Alternatively, for mssql use mssqlpo driver, 
-      which allows || operator.</td>
-  </tr>
-  <tr>

-<h2>DDL and Tuning</h2>
-There are database design tools such as ERWin or Dezign that allow you to generate data definition language commands such as ALTER TABLE or CREATE INDEX from Entity-Relationship diagrams. 
-<p>
-However if you prefer to use a PHP-based table creation scheme, adodb provides you with this feature. Here is the code to generate the SQL to create a table with: 
-<ol>
-	<li> Auto-increment primary key 'ID', </li>
-	<li>The person's 'NAME' VARCHAR(32) NOT NULL and defaults to '', </li>
-	<li>The date and time of record creation 'CREATED', </li>
-	<li> The person's 'AGE', defaulting to 0, type NUMERIC(16). </li>
-</ol>
-<p>
-Also create a compound index consisting of 'NAME' and 'AGE': 
-<pre>
-$datadict = <strong>NewDataDictionary</strong>($connection);
-$flds = " 
-<font color="#660000">  ID I AUTOINCREMENT PRIMARY,
-  NAME C(32) DEFAULT '' NOTNULL,
-  CREATED T DEFTIMESTAMP,
-  AGE N(16) DEFAULT 0</font>
-";
-$sql1 = $datadict-><strong>CreateTableSQL</strong>('tabname', $flds);
-$sql2 = $datadict-><strong>CreateIndexSQL</strong>('idx_name_age', 'tabname', 'NAME,AGE');
-</pre>
-
-<h3>Data Types</h3>
-<p>Stick to a few data types that are available in most databases. Char, varchar 
-  and numeric/number are supported by most databases. Most other data types (including 
-  integer, boolean and float) cannot be relied on being available. I recommend 
-  using char(1) or number(1) to hold booleans. </p>
-<p>Different databases have different ways of representing dates and timestamps/datetime. 
-  ADOdb attempts to display all dates in ISO (YYYY-MM-DD) format. ADOdb also provides 
-  DBDate( ) and DBTimeStamp( ) to convert dates to formats that are acceptable 
-  to that database. Both functions accept Unix integer timestamps and date strings 
-  in ISO format.</p>
-<pre>$date1 = $connection-&gt;DBDate(time( ));<br>$date2 = $connection-&gt;DBTimeStamp('2002-02-23 13:03:33');</pre>
-<p>We also provide functions to convert database dates to Unix timestamps:</p>
-<pre>$unixts = $recordset-&gt;UnixDate('#2002-02-30#'); <font color="green"># MS Access date =&gt; unix timestamp</font></pre>
-<p>The maximum length of a char/varchar field is also database specific. You can 
-  only assume that field lengths of up to 250 characters are supported. This is 
-  normally impractical for web based forum or content management systems. You 
-  will need to be familiar with how databases handle large objects (LOBs). ADOdb 
-  implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to 
-  update fields holding Binary Large Objects (eg. pictures) and Character Large 
-  Objects (eg. HTML articles):</p>
-<pre><font color=green># for oracle </font>
-$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1,empty_blob())'); 
-$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1'); 
-   
-<font color=green># non-oracle databases</font>
-$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)'); 
-$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
-</pre>
-<p>Null handling is another area where differences can occur. This is a mine-field, 
-  because 3-value logic is tricky.
-<p>In general, I avoid using nulls except for dates and default all my numeric 
-  and character fields to 0 or the empty string. This maintains consistency with 
-  PHP, where empty strings and zero are treated as equivalent, and avoids SQL 
-  ambiguities when you use the ANY and EXISTS operators. However if your database 
-  has significant amounts of missing or unknown data, using nulls might be a good 
-  idea. 
-  <p>
-  ADOdb also supports a portable <a href=http://phplens.com/adodb/reference.functions.concat.html#ifnull>IfNull</a> function, so you can define what to display
-  if the field contains a null.
-<h3><b>Stored Procedures</b></h3>
-<p>Stored procedures are another problem area. Some databases allow recordsets 
-  to be returned in a stored procedure (Microsoft SQL Server and Sybase), and 
-  others only allow output parameters to be returned. Stored procedures sometimes 
-  need to be wrapped in special syntax. For example, Oracle requires such code 
-  to be wrapped in an anonymous block with BEGIN and END. Also internal sql operators 
-  and functions such as +, ||, TRIM( ), SUBSTR( ) or INSTR( ) vary between vendors. 
-</p>
-<p>An example of how to call a stored procedure with 2 parameters and 1 return 
-  value follows:</p>
-<pre>	switch ($db->databaseType) {
-	case '<font color="#993300">mssql</font>':
-	  $sql = <font color="#000000"><font color="#993333">'<font color="#993300">SP_RUNSOMETHING</font>'</font></font>; break;
-	case '<font color="#993300">oci8</font>':
-	  $sql = 
-<font color="#993300">	  </font><font color="#000000"><font color="#993300">&quot;declare RETVAL integer;begin :RETVAL := </font><font color="#000000"><font color="#993333"><font color="#993300">SP_RUNSOMETHING</font></font></font><font color="#993300">(:myid,:group);end;&quot;;
-</font>	  break;</font>
-	default:
-	  die('<font color="#993300">Unsupported feature</font>');
-	}
-<font color="#000000"><font color="green">	# @RETVAL = SP_RUNSOMETHING @myid,@group</font>
-	$stmt = $db-&gt;PrepareSP($sql);	<br>	$db-&gt;Parameter($stmt,$id,'<font color="#993300">myid</font>'); 
-	$db-&gt;Parameter($stmt,$group,'<font color="#993300">group</font>');
-	<font color="green"># true indicates output parameter<br>	</font>$db-&gt;Parameter($stmt,$ret,'<font color="#993300">RETVAL</font>',true); 
-	$db-&gt;Execute($stmt); </font></pre>
-<p>As you can see, the ADOdb API is the same for both databases. But the stored 
-  procedure SQL syntax is quite different between databases and is not portable, 
-  so be forewarned! However sometimes you have little choice as some systems only 
-  allow data to be accessed via stored procedures. This is when the ultimate portability 
-  solution might be the only solution: <i>treating portable SQL as a localization 
-  exercise...</i></p>
-<h3><b>SQL as a Localization Exercise</b></h3>
-<p> In general to provide real portability, you will have to treat SQL coding 
-  as a localization exercise. In PHP, it has become common to define separate 
-  language files for English, Russian, Korean, etc. Similarly, I would suggest 
-  you have separate Sybase, Intebase, MySQL, etc files, and conditionally include 
-  the SQL based on the database. For example, each MySQL SQL statement would be 
-  stored in a separate variable, in a file called 'mysql-lang.inc.php'.</p>
-<pre>$sqlGetPassword = '<font color="#993300">select password from users where userid=%s</font>';
-$sqlSearchKeyword = &quot;<font color="#993300">SELECT * FROM articles WHERE match (title,body) against (%s</font>)&quot;;</pre>
-<p>In our main PHP file:</p>
-<pre><font color=green># define which database to load...</font>
-<b>$database = '<font color="#993300">mysql</font>';
-include_once(&quot;<font color="#993300">$database-lang.inc.php</font>&quot;);</b>
-
-$db = &amp;NewADOConnection($database);
-$db->PConnect(...) or die('<font color="#993300">Failed to connect to database</font>');
-
-<font color=green># search for a keyword $word</font>
-$rs = $db-&gt;Execute(sprintf($sqlSearchKeyWord,$db-&gt;qstr($word)));</pre>
-<p>Note that we quote the $word variable using the qstr( ) function. This is because 
-  each database quotes strings using different conventions.</p>
-<p>
-<h3>Final Thoughts</h3>
-<p>The best way to ensure that you have portable SQL is to have your data tables designed using 
-sound principles. Learn the theory of normalization and entity-relationship diagrams and model 
-your data carefully. Understand how joins and indexes work and how they are used to tune performance.

-<pre>		You say eether and I say eyether, 
-		You say neether and I say nyther; 
-		Eether, eyether, neether, nyther - 
-		Let's call the whole thing off ! 
-<br>
-		You like potato and I like po-tah-to, 
-		You like tomato and I like to-mah-to; 
-		Potato, po-tah-to, tomato, to-mah-to - 
-		Let's call the whole thing off ! 
-</pre>
-<p>I love this song, especially the version with Louis Armstrong and Ella singing 
-  duet. It is all about how hard it is for two people in love to be compatible 
-  with each other. It's about compromise and finding a common ground, and that's 
-  what this article is all about. 
-<p>PHP is all about creating dynamic web-sites with the least fuss and the most 
-  fun. To create these websites we need to use databases to retrieve login information, 
-  to splash dynamic news onto the web page and store forum postings. So let's 
-  say we were using the popular MySQL database for this. Your company has done 
-  such a fantastic job that the Web site is more popular than your wildest dreams. 
-  You find that MySQL cannot scale to handle the workload; time to switch databases. 
-<p> Unfortunately in PHP every database is accessed slightly differently. To connect 
-  to MySQL, you would use <i>mysql_connect()</i>; when you decide to upgrade to 
-  Oracle or Microsoft SQL Server, you would use <i>ocilogon() </i>or <i>mssql_connect()</i> 
-  respectively. What is worse is that the parameters you use for the different 
-  connect functions are different also.. One database says po-tato, the other 
-  database says pota-to. Oh-oh. 
-<h3>Let's NOT call the whole thing off</h3>
-<p>A database wrapper library such as ADODB comes in handy when you need to ensure portability. It provides 
-  you with a common API to communicate with any supported database so you don't have to call things off. <p>
-
-<p>ADODB stands for Active Data Objects DataBase (sorry computer guys are sometimes 
-  not very original). ADODB currently supports MySQL, PostgreSQL, Oracle, Interbase, 
-  Microsoft SQL Server, Access, FoxPro, Sybase, ODBC and ADO. You can download 
-  ADODB from <a href=http://php.weblogs.com/adodb></a><a href="http://php.weblogs.com/adodb">http://php.weblogs.com/adodb</a>.
-<h3>MySQL Example</h3>
-<p>The most common database used with PHP is MySQL, so I guess you should be familiar 
-  with the following code. It connects to a MySQL server at <i>localhost</i>, 
-  database <i>mydb</i>, and executes an SQL select statement. The results are 
-  printed, one line per row. 
-<pre><font color="#666600">$db = <b>mysql_connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;);
-<b>mysql_select_db</b>(&quot;mydb&quot;,$db);</font>

-<p>The above code has been color-coded by section. The first section is the connection 
-  phase. The second is the execution of the SQL, and the last section is displaying 
-  the fields. The <i>while</i> loop scans the rows of the result, while the <i>for</i> 
-  loop scans the fields in one row.</p>
-<p>Here is the equivalent code in ADODB</p>
-<pre><b><font color="#666600"> include(&quot;adodb.inc.php&quot;);</font></b><font color="#666600">
- $db = <b>NewADOConnection</b>('mysql');
- $db-&gt;<b>Connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;, &quot;mydb&quot;);</font>
- <font color="#663300">$result = $db-&gt;<b>Execute</b>(&quot;SELECT * FROM employees&quot;);
- </font><font color="#663300"></font><code><font color="#663300">if ($result === false) die(&quot;failed&quot;)</font></code><code><font color="#663300">;</font></code>  
- <font color="#006666"><b>while</b> (!$result-&gt;EOF) &#123;
-	<b>for</b> ($i=0, $max=$result-&gt;<b>FieldCount</b>(); $i &lt; $max; $i++)
-		   <b>print</b> $result-&gt;fields[$i].' ';
-	$result-&gt;<b>MoveNext</b>();
-	<b>print</b> &quot;&lt;br&gt;\n&quot;;
- &#125;</font> </pre>
-<p></p>
-<p>Now porting to Oracle is as simple as changing the second line to <code>NewADOConnection('oracle')</code>. 
-  Let's walk through the code...</p>
-<h3>Connecting to the Database</h3>
-<p></p>
-<pre><b><font color="#666600">include(&quot;adodb.inc.php&quot;);</font></b><font color="#666600">
-$db = <b>NewADOConnection</b>('mysql');
-$db-&gt;<b>Connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;, &quot;mydb&quot;);</font></pre>
-<p>The connection code is a bit more sophisticated than MySQL's because our needs 
-  are more sophisticated. In ADODB, we use an object-oriented approach to managing 
-  the complexity of handling multiple databases. We have different classes to 
-  handle different databases. If you aren't familiar with object-oriented programing, 
-  don't worry -- the complexity is all hidden away in the<code> NewADOConnection()</code> 
-  function.</p>
-<p>To conserve memory, we only load the PHP code specific to the database you 
-  are connecting to. We do this by calling <code>NewADOConnection(databasedriver)</code>. 
-  Legal database drivers include <i>mysql, mssql, oracle, oci8, postgres, sybase, 
-  vfp, access, ibase </i>and many others.</p>
-<p>Then we create a new instance of the connection class by calling <code>NewADOConnection()</code>. 
-  Finally we connect to the database using <code>$db-&gt;Connect(). </code></p>
-<h3>Executing the SQL</h3>
-<p><code><font color="#663300">$result = $db-&gt;<b>Execute</b>(&quot;SELECT * 
-  FROM employees&quot;);<br>
-  if ($result === false) die(&quot;failed&quot;)</font></code><code><font color="#663300">;</font></code> 
-  <br>
-</p>
-<p>Sending the SQL statement to the server is straight forward. Execute() will 
-  return a recordset object on successful execution. You should check $result 
-  as we do above.
-<p>An issue that confuses beginners is the fact that we have two types of objects 
-  in ADODB, the connection object and the recordset object. When do we use each?
-<p>The connection object ($db) is responsible for connecting to the database, 
-  formatting your SQL and querying the database server. The recordset object ($result) 
-  is responsible for retrieving the results and formatting the reply as text or 
-  as an array.
-<p>The only thing I need to add is that ADODB provides several helper functions 
-  for making INSERT and UPDATE statements easier, which we will cover in the Advanced 
-  section. 
-<h3>Retrieving the Data<br>
-</h3>
-<pre><font color="#006666"><b>while</b> (!$result-&gt;EOF) &#123;
-   <b>for</b> ($i=0, $max=$result-&gt;<b>FieldCount</b>(); $i &lt; $max; $i++)
-	   <b>print</b> $result-&gt;fields[$i].' ';
-   $result-&gt;<b>MoveNext</b>();
-   <b>print</b> &quot;&lt;br&gt;\n&quot;;
-&#125;</font></pre>
-<p>The paradigm for getting the data is that it's like reading a file. For every 
-  line, we check first whether we have reached the end-of-file (EOF). While not 
-  end-of-file, loop through each field in the row. Then move to the next line 
-  (MoveNext) and repeat. 
-<p>The <code>$result-&gt;fields[]</code> array is generated by the PHP database 
-  extension. Some database extensions do not index the array by field name. 
-  To force indexing by name - that is associative arrays - 
-  use the $ADODB_FETCH_MODE global variable. 
-<pre>
-	$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_NUM;
-	$rs1 = $db->Execute('select * from table');
-	$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_ASSOC;
-	$rs2 = $db->Execute('select * from table');
-	print_r($rs1->fields); // shows <i>array([0]=>'v0',[1] =>'v1')</i>
-	print_r($rs2->fields); // shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
-</pre>
-<p>
-As you can see in the above example, both recordsets store and use different fetch modes
-based on the $ADODB_FETCH_MODE setting when the recordset was created by Execute().</p>
-<h2>ADOConnection<a name="ADOConnection"></a></h2>
-<p>Object that performs the connection to the database, executes SQL statements 
-  and has a set of utility functions for standardising the format of SQL statements 
-  for issues such as concatenation and date formats.</p>
-  
-<h3>Other Useful Functions</h3>
-<p><code>$recordset-&gt;Move($pos)</code> scrolls to that particular row. ADODB supports forward 
-  scrolling for all databases. Some databases will not support backwards scrolling. 
-  This is normally not a problem as you can always cache records to simulate backwards 
-  scrolling. 
-<p><code>$recordset-&gt;RecordCount()</code> returns the number of records accessed by the 
-  SQL statement. Some databases will return -1 because it is not supported. 
-<p><code>$recordset-&gt;GetArray()</code> returns the result as an array. 
-<p><code>rs2html($recordset)</code> is a function that is generates a HTML table based on the 
-  $recordset passed to it. An example with the relevant lines in bold:
-<pre>   include('adodb.inc.php'); 
-   <b>include('tohtml.inc.php');</b> /* includes the rs2html function */
-   $conn = &amp;ADONewConnection('mysql'); 
-   $conn-&gt;PConnect('localhost','userid','password','database');
-   $rs = $conn-&gt;Execute('select * from table');
-  <b> rs2html($rs)</b>; /* recordset to html table */ </pre>
-<p>There are many other helper functions that are listed in the documentation available at <a href="http://php.weblogs.com/adodb_manual"></a><a href="http://php.weblogs.com/adodb_manual">http://php.weblogs.com/adodb_manual</a>. 
-<h2>Advanced Material</h2>
-<h3>Inserts and Updates </h3>
-<p>Let's say you want to insert the following data into a database. 
-<p><b>ID</b> = 3<br>
-  <b>TheDate</b>=mktime(0,0,0,8,31,2001) /* 31st August 2001 */<br>
-  <b>Note</b>= sugar why don't we call it off 
-<p>When you move to another database, your insert might no longer work.</p>
-<p>The first problem is that each database has a different default date format. 
-  MySQL expects YYYY-MM-DD format, while other databases have different defaults. 
-  ADODB has a function called DBDate() that addresses this issue by converting 
-  converting the date to the correct format.</p>
-<p>The next problem is that the <b>don't</b> in the Note needs to be quoted. In 
-  MySQL, we use <b>don\'t</b> but in some other databases (Sybase, Access, Microsoft 
-  SQL Server) we use <b>don''t. </b>The qstr() function addresses this issue.</p>
-<p>So how do we use the functions? Like this:</p>
-<pre>$sql = &quot;INSERT INTO table (id, thedate,note) values (&quot; 
-   . $<b>ID</b> . ','
-   . $db-&gt;DBDate($<b>TheDate</b>) .','
-   . $db-&gt;qstr($<b>Note</b>).&quot;)&quot;;
-$db-&gt;Execute($sql);</pre>
-<p>ADODB also supports <code>$connection-&gt;Affected_Rows()</code> (returns the 
-  number of rows affected by last update or delete) and <code>$recordset-&gt;Insert_ID()</code> 
-  (returns last autoincrement number generated by an insert statement). Be forewarned 
-  that not all databases support the two functions.<br>
-</p>
-<h3>MetaTypes</h3>
-<p>You can find out more information about each of the fields (I use the words 
-  fields and columns interchangebly) you are selecting by calling the recordset 
-  method <code>FetchField($fieldoffset)</code>. This will return an object with 
-  3 properties: name, type and max_length. 
-<pre>For example:</pre>
-<pre>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>$f0 = $recordset-&gt;FetchField(0);
-</pre>
-<p>Then <code>$f0-&gt;name</code> will hold <i>'adata'</i>, <code>$f0-&gt;type</code> 
-  will be set to '<i>date'</i>. If the max_length is unknown, it will be set to 
-  -1. 
-<p>One problem with handling different databases is that each database often calls 
-  the same type by a different name. For example a <i>timestamp</i> type is called 
-  <i>datetime</i> in one database and <i>time</i> in another. So ADODB has a special 
-  <code>MetaType($type, $max_length)</code> function that standardises the types 
-  to the following: 
-<p>C: character and varchar types<br>
-  X: text or long character (eg. more than 255 bytes wide).<br>
-  B: blob or binary image<br>
-  D: date<br>
-  T: timestamp<br>
-  L: logical (boolean)<br>
-  I: integer<br>
-  N: numeric (float, double, money) 
-<p>In the above date example, 
-<p><code>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>
-  $f0 = $recordset-&gt;FetchField(0);<br>
-  $type = $recordset-&gt;MetaType($f0-&gt;type, $f0-&gt;max_length);<br>
-  print $type; /* should print 'D'</code> */
-<p> 
-<p><b>Select Limit and Top Support</b> 
-<p>ADODB has a function called $connection->SelectLimit($sql,$nrows,$offset) that allows
-you to retrieve a subset of the recordset. This will take advantage of native
-SELECT TOP on Microsoft products and SELECT ... LIMIT with PostgreSQL and MySQL, and
-emulated if the database does not support it.
-<p><b>Caching Support</b> 
-<p>ADODB allows you to cache recordsets in your file system, and only requery the database
-server after a certain timeout period with $connection->CacheExecute($secs2cache,$sql) and 
-$connection->CacheSelectLimit($secs2cache,$sql,$nrows,$offset).
-<p><b>PHP4 Session Handler Support</b> 
-<p>ADODB also supports PHP4 session handlers. You can store your session variables 
-  in a database for true scalability using ADODB. For further information, visit 
-  <a href="http://php.weblogs.com/adodb-sessions"></a><a href="http://php.weblogs.com/adodb-sessions">http://php.weblogs.com/adodb-sessions</a>
-<h3>Commercial Use Encouraged</h3>
-<p>If you plan to write commercial PHP applications that you want to resell, you should consider ADODB. It has been released using the lesser GPL, which means you can legally include it in commercial applications, while keeping your code proprietary. Commercial use of ADODB is strongly encouraged! We are using it internally for this reason.<p>

-<h2>Conclusion</h2>
-<p>As a thank you for finishing this article, here are the complete lyrics for 
-  <i>let's call the whole thing off</i>.<br>
-  <br>
-<pre>
-   Refrain 
-<br>
-		You say eether and I say eyether, 
-		You say neether and I say nyther; 
-		Eether, eyether, neether, nyther - 
-		Let's call the whole thing off ! 
-<br>
-		You like potato and I like po-tah-to, 
-		You like tomato and I like to-mah-to; 
-		Potato, po-tah-to, tomato, to-mah-to - 
-		Let's call the whole thing off ! 
-<br>
-But oh, if we call the whole thing off, then we must part. 
-And oh, if we ever part, then that might break my heart. 
-<br>
-		So, if you like pajamas and I like pa-jah-mas, 
-		I'll wear pajamas and give up pa-jah-mas. 
-		For we know we 
-		Need each other, so we 
-		Better call the calling off off. 
-		Let's call the whole thing off ! 
-<br>
-   Second Refrain 
-<br>
-		You say laughter and I say lawfter, 
-		You say after and I say awfter; 
-		Laughter, lawfter, after, awfter - 
-		Let's call the whole thing off ! 
-<br>
-		You like vanilla and I like vanella, 
-		You, sa's'parilla and I sa's'parella; 
-		Vanilla, vanella, choc'late, strawb'ry - 
-		Let's call the whole thing off ! 
-<br>
-But oh, if we call the whole thing off, then we must part. 
-And oh, if we ever part, then that might break my heart. 
-<br>
-		So, if you go for oysters and I go for ersters, 
-		I'll order oysters and cancel the ersters. 
-		For we know we 
-		Need each other, so we 
-		Better call the calling off off. 
-		Let's call the whole thing off !
