run code in 300+ PHP versions simultaneously
<?php $a = array('zero', 'one', 'two'); foreach ($a as &$b) {} echo $b . PHP_EOL; foreach ($a as $b) {} echo $b;

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).
