run code in 300+ PHP versions simultaneously
<?php $xmls = [6, 3, 2, 5, 4, 1]; echo memory_get_usage() . "\n\n"; usort($xmls, function($a, $b) { static $documents = array(); if (!isset($documents[$a])) { $documents[$a] = true; } if (!isset($documents[$b])) { $documents[$b] = true; } if ($a == $b) { $result = 0; } else { $result = $a < $b ? -1 : 1; } echo "a = {$a}, b = {$b}, result = {$result}\n" , memory_get_usage() , "\n" , print_r($documents, true) , "\n"; return $result; }); echo memory_get_usage() . "\n" . print_r($xmls, true) . "\n";

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).
