RFC2396 Compliant.
See:- http://www.ietf.org/rfc/rfc2396.txt
<?php
function isValidURI( $sURI ){
//--> Complies with RFC2396
return ( 1 === preg_match('~^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\\?([^#]*))?(#(.*))?~', $sURI) ) ? true : false ;
}
?>

more expressive IMHO
<?php
function isValidURI( $sURI ){
//--> Complies with RFC2396
return (bool) preg_match('~^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\\?([^#]*))?(#(.*))?~', $sURI);
}
?>

the int returned reflects the match, so this is fine unless your a nazi using ===
<?php
function isValidURI( $sURI ){
//--> Complies with RFC2396
return preg_match('~^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\\?([^#]*))?(#(.*))?~', $sURI);
}
?>

Not a huge fan of prefixing vars, or camelcase
<?php
function is_valid_uri($uri) {
return preg_match('~^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\\?([^#]*))?(#(.*))?~', $uri);
}
?>

There's nothing Nazi about === at all. Quite the opposite in my opinion.

In the right context yes... but in this case that is excessive since the simple int in a comparison is still completely valid... hence why it returns an int in the first place

It was introduced with 5, which is probably why no one mentioned it. Either way PHP sucks lol

Don't have the code at the moment but you could always try to get the file contents of the URL listed, and if it exists then it is a valid URL in that the structure is correct and it actually returns a page (not an error).
