run code in 300+ PHP versions simultaneously
<?php $a = new StdClass(); $b = new StdClass(); $array1 = array($a, $a, $b); $array2 = array($a, $b, $b); $count1 = array(); foreach ($array1 as $val) { $hash = spl_object_hash($val); if (! isset($count1[$hash])) { $count1[$hash] = 0; } $count1[$hash]++; } var_dump($count1);

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).
