run code in 300+ PHP versions simultaneously
<?php $l = array('test' => 'a', 'test2' => 'b'); foreach($l as $k => $v){ print($k . ": " . $v); }

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).
