run code in 300+ PHP versions simultaneously
<?php class A { public function c(A $a) {} } class B extends A { public function c(B $a) {} } $b = new B(); $b->c(new 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).
