run code in 300+ PHP versions simultaneously
<?php $array = [0, 1, 2]; foreach ($array as $key=> &$val) { var_dump(current($array)); //var_dump($key); }

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).
