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' ;
}

Changelog :
December 15 th 2004
- Added new TLD ' s - . jobs , . mobi , . post and . travel . They are official , but not yet active .
August 31 th 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 27 th , 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 8 th , 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

About ValidateEmailSyntax () :

Usage :
validateEmailSyntax ( url_to_check [, options ])

the url are required , optional , or not allowed . Each option

The default options are changed to :
s - H - S - E + F - u + P - a + I - p - f - q - r -
This only allows an address of " name@domain " .
