run code in 300+ PHP versions simultaneously
<?php $data = array(8,4,1,9,5,7,3,2,6,0); function merge_sort($list){ if(count($list) <= 1) { return $list; } $middle = count($list)/2; $left = merge_sort(array_slice($list, 0, $middle)); $right = merge_sort(array_slice($list, $middle; count($list))); for($x = 0;$x < count($list); $x++){ if($x < count($left)){ $list[$x] = $left[$x]; } if($x >= count($left) && $x < count($right)){ $list[$x] = $right[$x]; } } return $list; } merge_sort($data);

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).
