<?php $x = array(-3,5,1,3,2,10); function array_rev($array) { $half_count = count($array)/2; $count = count($array); for ($i = 0; $i <= $half_count; $i++) { $holder = $array[$i]; $array[$i] = $array[($count - ($i + 1)]; $array[($count - ($i + 1)] = $holder; } echo $array; } array_rev($x);

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).
