<?php $sweet = array('a' => 'apple', 'b' => 'banana'); $fruits = array('sweet' => $sweet, 'sour' => 'lemon'); $stuff = new RecursiveIteratorIterator(new RecursiveArrayIterator($fruits), RecursiveIteratorIterator:: CATCH_GET_CHILD); foreach ($stuff as $fruit) { echo is_array($fruit) ? null : $fruit; }

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).
