Hi, > return (preg_match("/^[a-z0-9]+$/i", $string));
That a-z0-9 is where you can do it. Just add ! or . or ? to the end: a-z0-9!?. Also, if you want upper case letters, make sure you add A-Z: A-Za-z0-9!?. -Dan Joseph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
