note 113255 added to function.is-int

Remember that some source of data always give a string data type. That's the case with cookies and $_GET. if you need to check against those values, try to convert them into numbers first. The easiest way of doing so is adding a zero before your var, just like: <?php $var = '15'; // ...or $var = $_COOKIE['myvar'] or $var = $_GET['myvar']... is_int($var); // now returns FALSE $var += 0; is_int($var); // now returns TRUE ?> ---- Server IP: 69.147.83.199 Probable Submitter: 79.1.147.108 ---- Manual Page -- http://php.net/manual/en/function.is-int.php Edit -- https://master.php.net/note/edit/113255 Del: integrated -- https://master.php.net/note/delete/113255/integrated Del: useless -- https://master.php.net/note/delete/113255/useless Del: bad code -- https://master.php.net/note/delete/113255/bad+code Del: spam -- https://master.php.net/note/delete/113255/spam Del: non-english -- https://master.php.net/note/delete/113255/non-english Del: in docs -- https://master.php.net/note/delete/113255/in+docs Del: other reasons-- https://master.php.net/note/delete/113255 Reject -- https://master.php.net/note/reject/113255 Search -- https://master.php.net/manage/user-notes.php
