As Carlos points out (2 comments above) you don't want people to mess around with your regexp. To avoid this I use this preg_addslashes function: <? function preg_addslashes ($foo) { return preg_replace("/([^A-z0-9_-]|[\\\[\]])/", "\\\\\\1", $foo); } $foo = "([/com|et\])"; $true = preg_match ("/^".preg_addslashes($foo)."$/", $foo); // without preg_addslashes you'd get an error and $true = false. ?> -- http://www.php.net/manual/en/function.preg-match.php http://master.php.net/manage/user-notes.php?action=edit+30055 http://master.php.net/manage/user-notes.php?action=delete+30055 http://master.php.net/manage/user-notes.php?action=reject+30055
