note 55390 added to function.is-int

I wrote some usefull function again :D If you want to check if your data from _POST or _GET is int you can't use normal function is_int() beacuse external datas are always as strings ;] For this you can use that: <?php /* * Find whether a variable is only with digits * * @author FanFataL * @param mixed * @return bool */ function isint($mixed) { return (bool)preg_match('/^[\d]+$/', $mixed); } // Example: is_int($_POST['age']); // Always false isint($_POST['age']); // true when it is a number ;] ?> Greatings ;-) ... ---- Manual Page -- http://www.php.net/manual/en/function.is-int.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55390 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55390&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55390&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55390&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55390&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55390&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55390&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55390&report=yes Search -- http://master.php.net/manage/user-notes.php
