+About validateUrlSyntax():
+ This function will verify if a http URL is formatted properly, returning
+ either with true or false.
+
+ I used rfc #2396 URI: Generic Syntax as my guide when creating the
+ regular expression. For all the details see the comments below.
+
+
+Usage:
+ validateUrlSyntax( url_to_check[, options])
+
+ url_to_check - string - The url to check
+
+ options - string - A optional string of options to set which parts of
+ the url are required, optional, or not allowed. Each option
+ must be followed by a "+" for required, "?" for optional, or
+ "-" for not allowed.
+
+ s - Scheme. Allows "+?-", defaults to "s?"
+ H - http:// Allows "+?-", defaults to "H?"
+ S - https:// (SSL). Allows "+?-", defaults to "S?"
+ E - mailto: (email). Allows "+?-", defaults to "E-"
+ F - ftp:// Allows "+?-", defaults to "F-"
+ Dependant on scheme being enabled
+ u - User section. Allows "+?-", defaults to "u?"
+ P - Password in user section. Allows "+?-", defaults to "P?"
+ Dependant on user section being enabled
+ a - Address (ip or domain). Allows "+?-", defaults to "a+"
+ I - Ip address. Allows "+?-", defaults to "I?"
+ If I+, then domains are disabled
+ If I-, then domains are required
+ Dependant on address being enabled
+ p - Port number. Allows "+?-", defaults to "p?"
+ f - File path. Allows "+?-", defaults to "f?"
+ q - Query section. Allows "+?-", defaults to "q?"
+ r - Fragment (anchor). Allows "+?-", defaults to "r?"
+
+ Paste the funtion code, or include_once() this template at the top of the page
+ you wish to use this function.
+
+
+Examples:
+ validateUrlSyntax('http://george@www.cnn.com/#top')
+
+ validateUrlSyntax('https://games.yahoo.com:8080/board/chess.htm?move=true')
+
+ validateUrlSyntax('http://www.hotmail.com/', 's+u-I-p-q-r-')
+
+ validateUrlSyntax('/directory/file.php#top', 's-u-a-p-f+')
+
+
+ if (validateUrlSyntax('http://www.canowhoopass.com/', 'u-'))
+ {
+ echo 'URL SYNTAX IS VERIFIED';
+ } else {
+ echo 'URL SYNTAX IS ILLEGAL';
+ }

+Last Edited:
+ December 15th 2004
+
+
+Changelog:
+ December 15th 2004
+ -Added new TLD's - .jobs, .mobi, .post and .travel. They are official, but not yet active.
+
+ August 31th 2004
+ -Fixed bug allowing empty username even when it was required
+ -Changed and added a few options to add extra schemes
+ -Added mailto: ftp:// and http:// options
+ -https option was 'l' now it is 'S' (capital)
+ -Added password option. Now passwords can be disabled while usernames are ok (for email)
+ -IP Address option was 'i' now it is 'I' (capital)
+ -Options are now case sensitive
+ -Added validateEmailSyntax() and validateFtpSyntax() functions below<br>
+
+ August 27th, 2004
+ -IP group range is more specific. Used to allow 0-299. Now it is 0-255
+ -Port range more specific. Used to allow 0-69999. Now it is 0-65535<br>
+ -Fixed bug disallowing 'i-' option.<br>
+ -Changed license to GPL
+
+ July 8th, 2004
+ -Fixed bug disallowing 'l-' option. Thanks Dr. Cheap
+
+ June 15, 2004
+ -Added options parameter to make it easier for people to plug the function in
+ without needed to rework the code.
+ -Split the example application away from the function
+
+ June 1, 2004
+ -Complete rewrite
+ -Now more modular
+ -Easier to disable sections
+ -Easier to port to other languages
+ -Easier to port to verify email addresses
+ -Uses only simple regular expressions so it is more portable
+ -Follows RFC closer for domain names. Some "play" domains may break
+ -Renamed from 'verifyUrl()' to 'validateUrlSyntax()'
+ -Removed extra code which added 'http://' and trailing '/' if it was missing
+ -That code was better suited for a massaging function, not verifying
+ -Bug fixes:
+ -Now splits up and forces '/path?query#fragment' order
+ -No longer requires a path when using a query or fragment
+
+ August 29, 2003
+ -Allowed port numbers above 9999. Now allows up to 69999
+
+ Sometime, 2002
+ -Added new top level domains
+ -aero, coop, museum, name, info, biz, pro
+
+ October 5, 2000
+ -First Version
+
+
+Intentional Limitations:
+ -Does not verify url actually exists. Only validates the syntax
+ -Strictly follows the RFC standards. Some urls exist in the wild which will
+ not validate. Including ones with square brackets in the query section '[]'
+
+
+Known Problems:
+ -None at this time
