<?php interface A { public foo(); } interface B extends A { public bar(); } interface C { public exec(A $obj); } class TestB implements B {  public function bar() { echo 'bar';} public function foo() { echo 'foo';} } class Test implements C { function exec(B $obj) { $obj->foo(); } } $testB = new TestB; $test = new Test; $test->exec($testB);

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).
