run code in 300+ PHP versions simultaneously
<?php for($i = 0; $i < 100000; $i++){ $x = implode("", array("xxxx", "xxxx", "xxxx","xxxx")); } echo $x;

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).
