note 75529 deleted from function.ctype-digit by philip

Note Submitter: robert at mediamonks dot com ---- 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.
