I found out that in_array will *not* find an associative array within a haystack of associative arrays in strict mode if the keys were not generated in the *same order*: <?php $needle = array( 'fruit'=>'banana', 'vegetable'=>'carrot' ); $haystack = array( array('vegetable'=>'carrot', 'fruit'=>'banana'), array('fruit'=>'apple', 'vegetable'=>'celery') ); echo in_array($needle, $haystack, true) ? 'true' : 'false'; // Output is 'false' echo in_array($needle, $haystack) ? 'true' : 'false'; // Output is 'true' ?> I had wrongly assumed the order of the items in an associative array were irrelevant, regardless of whether 'strict' is TRUE or FALSE: The order is irrelevant *only* if not in strict mode. ---- Server IP: 216.235.13.26 Probable Submitter: 74.59.204.182 ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/88260 Del: integrated -- https://master.php.net/note/delete/88260/integrated Del: useless -- https://master.php.net/note/delete/88260/useless Del: bad code -- https://master.php.net/note/delete/88260/bad+code Del: spam -- https://master.php.net/note/delete/88260/spam Del: non-english -- https://master.php.net/note/delete/88260/non-english Del: in docs -- https://master.php.net/note/delete/88260/in+docs Del: other reasons-- https://master.php.net/note/delete/88260 Reject -- https://master.php.net/note/reject/88260 Search -- https://master.php.net/manage/user-notes.php
