note 55392 added to function.parse-url

Some developers look here for a mean of validating an url. So here is a simple way of validating an url. $uri = 'http://some-domain-name.org'; if( preg_match( '/^(http|https):\/\/[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}' .'((:[0-9]{1,5})?\/.*)?$/i' ,$uri)) { echo $uri . ' is a valid url'; } else { echo $uri . ' is NOT a valid url'; } Beware - it only validates scemes: http and https, and it only takes into account host and port part of the uri. It does not accept username and password. For an email validator you could look at http://gaarsmand.com/index.php/IT_l%F8sninger/Kode_eksempler/PHP_kode. ---- Manual Page -- http://www.php.net/manual/en/function.parse-url.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55392 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55392&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55392&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55392&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55392&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55392&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55392&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55392&report=yes Search -- http://master.php.net/manage/user-notes.php
