run code in 300+ PHP versions simultaneously
<?php $arr = array('a'=>'first', 'b'=>'second', 'c'=>'third'); foreach ($arr as $s); // do nothing. maybe? print_r($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).
