run code in 300+ PHP versions simultaneously
<?php $foo = array(124); foreach ($foo as &$bar) { } foreach ($foo as $bar) { $bar = 123; } print_r($foo);

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).
