run code in 300+ PHP versions simultaneously
<?php class Foo { function a() { $this->b(); } } class Bar extends Foo { static function b() { echo "b"; } } $x = new Bar(); $x->a();

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).
