note 110720 added to function.ctype-alnum

Well, me too.. When I have to allow some more values in it, I use them in same way, and i create function for it.. $str = ""; function validate_username($str) { $allowed = array(".", "-", "_", "@", " "); // you can add here more value, you want to allow. if(ctype_alnum(str_replace($allowed, '', $str ))) { return $str; } else { $str = "Invalid Username"; return $str; } } ---- Server IP: 69.147.83.199 Probable Submitter: 49.15.87.221 ---- Manual Page -- http://www.php.net/manual/en/function.ctype-alnum.php Edit -- https://master.php.net/note/edit/110720 Del: integrated -- https://master.php.net/note/delete/110720/integrated Del: useless -- https://master.php.net/note/delete/110720/useless Del: bad code -- https://master.php.net/note/delete/110720/bad+code Del: spam -- https://master.php.net/note/delete/110720/spam Del: non-english -- https://master.php.net/note/delete/110720/non-english Del: in docs -- https://master.php.net/note/delete/110720/in+docs Del: other reasons-- https://master.php.net/note/delete/110720 Reject -- https://master.php.net/note/reject/110720 Search -- https://master.php.net/manage/user-notes.php
