note 75529 added to function.ctype-digit

I always used this function to check user input but it failed me when I wanted to check int's used in my script. This is caused by the fact that the function only functions right when the argument is a string. Here is a solution for this 'problem' : <?php $intCheckThis = 99; $blnResult = ctype_digit($intCheckThis); // returns FALSE $blnResult = ctype_digit(strval($intCheckThis)); // returns TRUE ?> Note that user input from form or request uri is always handled as string anyway. ---- Server IP: 83.137.20.120 Probable Submitter: 82.204.32.210 ---- Manual Page -- http://www.php.net/manual/en/function.ctype-digit.php Edit -- https://master.php.net/note/edit/75529 Del: integrated -- https://master.php.net/note/delete/75529/integrated Del: useless -- https://master.php.net/note/delete/75529/useless Del: bad code -- https://master.php.net/note/delete/75529/bad+code Del: spam -- https://master.php.net/note/delete/75529/spam Del: non-english -- https://master.php.net/note/delete/75529/non-english Del: in docs -- https://master.php.net/note/delete/75529/in+docs Del: other reasons-- https://master.php.net/note/delete/75529 Reject -- https://master.php.net/note/reject/75529 Search -- https://master.php.net/manage/user-notes.php
