run code in 300+ PHP versions simultaneously
<?php $array = [[1,2],[3,4]]; //foreach($array as list($x, $y)) { // echo $x . ' : ' . $y . PHP_EOL; //} while(list($x, $y) = each($array)) { var_dump($x); }

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).
