I think "thehiddenfire" wanted to say is that "ctype_alnum" would be like this: function ctype_alnum($text) { for ($i = 0; $i<strlen($text); $i++) { if (!ctype_alpha($text[$i]) && !ctype_digit($text[$i])) return false; } return true; } Note that I've changed the "if" condition to "&&". ---- Manual Page -- http://www.php.net/manual/en/function.ctype-alnum.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39810 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39810&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39810&report=yes Search -- http://master.php.net/manage/user-notes.php
