<?php interface Foo { public function setFoo(Foo $aFoo); } class Baz implements Foo { private $foo; private function setFoo(Baz $aFoo) // fatal error { $this->foo = $aFoo; } }

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
