<?php $arr1 = array("a"=>1, "b"=>2, "c"=>3); $arr2 = array("x"=>4, "y"=>5, "z"=>6); foreach($arr1 as $key => &$val) {} foreach($arr2 as $key => $val) {} var_dump($arr1); var_dump($arr2);

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).
