run code in 300+ PHP versions simultaneously
<?php $x = new stdClass(); $x->foo = 'foo'; $x->bar = 'bar'; foreach($x as $key => $val) { var_dump($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).
