note 74047 deleted from function.preg-match by colder

Note Submitter: Hayley Watson ---- RFC3986 offers a regular expression for matching URIs. Modified slightly: <?php preg_match( '_^(?:([^:/?#]+):)?(?://([^/?#]*))?'. '([^?#]*)(?:\?([^#]*))?(?:#(.*))?$_', $uri, $uri_parts); ?> recognises anything that is a valid URI according to that specification; $uri_parts is of course an array with the elements [0] => the entire URI (of course) [1] => the protocol scheme (e.g., http) [2] => the naming authority (the entity responsible for identifying the resource) [3] => the path [4] => the contents of any querystring [5] => any value of any fragment With the example http://www.php.net/manual/en/function.preg-match.php#id5827438 those parts are [0] => http://www.php.net/manual/en/function.preg-match.php#id5827438 [1] => http [2] => www.php.net [3] => /manual/en/function.preg-match.php [4] => [5] => id5827438 Of course, the parse_url() function is probably a much more legible solution - but it's amusing to note that PHP uses over 200 lines of C to implement that function!
