<?php $itemList = array( array(0), array(1), array(0,1), array(0,1,2,3,4), array(new stdClass), array(new stdClass, new stdClass), array(new stdClass, new stdClass, new stdClass) ); function doCompare($a, $b){ var_dump($a, $b); return $a === $b; }; foreach ($itemList as $item) { var_dump(array_udiff($item, $item, 'doCompare')); }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
