<?php $a = array('e' => 22, 'r' => 66, 't' => 88); $b = array('t' => 65); array_walk($a, function(&$value) { $value = 'e ' . $value; print $value ."\n"; }); print_r($a);

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).
