<?php class Foo implements IteratorAggregate { public function getIterator() { return array(); } } $foo = new Foo(); $i = new RecursiveTreeIterator($foo); foreach ($i as $val) { echo $val; }

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.
