run code in 300+ PHP versions simultaneously
<?php $a = [ 'a' => 1, 2 => 1, 'three' => 3, 4 => 5, 6 => 7, ]; foreach ($a as &$v) $v++; var_dump($a);

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).
