<?php $i = 0; $arr = array(); while ($i < 10) { $arr[] = $i; $arr["$i key"] = "$i value"; $i++; } foreach ($arr as $k => $v) { var_dump($k, $v); }

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).
