in_array() will always return true if a value in the haystack is of type bool(true). This always hold except when the needle is of type bool(false). Code: <?php $haystack = array(true); $needle = "anything except bool(false)"; $result = in_array($needle, $haystack); var_dump($result); #Will always be true ?> Solution: run in_array() with strict set to true. <?php in_array($needle, $haystack, true); ?> Tested on PHP 5.2.6 ---- Server IP: 69.147.83.197 Probable Submitter: 83.254.65.38 ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/98043 Del: integrated -- https://master.php.net/note/delete/98043/integrated Del: useless -- https://master.php.net/note/delete/98043/useless Del: bad code -- https://master.php.net/note/delete/98043/bad+code Del: spam -- https://master.php.net/note/delete/98043/spam Del: non-english -- https://master.php.net/note/delete/98043/non-english Del: in docs -- https://master.php.net/note/delete/98043/in+docs Del: other reasons-- https://master.php.net/note/delete/98043 Reject -- https://master.php.net/note/reject/98043 Search -- https://master.php.net/manage/user-notes.php
