run code in 300+ PHP versions simultaneously
<?php class a { public $u = 'u'; function getClass(){ echo get_class($this) ; } } class b extends a{ public $u = 'b'; } $b = new b(); $b->getClass();

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).
