<?php class Baz{} class Test implements Iterator { function key(){ return new Baz(); } function next(){} function valid(){ $this->count++; return $this->count < 4; } function current(){ return "foo"; } function rewind(){} } foreach(new Test as $x => $v) var_dump($x, $v);
based on XWE3L

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.
