<?php $a = array(2,1,3); $c = array(); foreach($a as $b){ $c[$b] = $b; } var_dump($c); foreach($c as $index => $d) $c[$index] = $d; var_dump($c);

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).
