<?php function prime($n) { $s = sqrt($n); for ($i = 2; $i <= $s; $i++) { if ($n % $i == 0) { return array_merge(prime($n/$i), array($i)); } } return array($n); } $prime = prime(42); print_r($prime); ?>

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).
