run code in 300+ PHP versions simultaneously
<?php $arr = [1, 2, 3]; foreach ($arr as &$a); // do nothing. maybe? foreach ($arr as $a); // do nothing. maybe? print_r($arr);

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).
