run code in 300+ PHP versions simultaneously
(<?php class A { function foo() { echo "A::foo\r\n"; } } class B extends A { function foo() { echo "B::foo\r\n"; } } $a = new A; $b = new B; $a->foo(); $b->foo(); $casted = (A)$b; $casted->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).
