<?php $myArray = array( "a", array( "a", "b", array( "a", "b", "c", array( "a", "b", "c", "d", array("the end") ) ) ) ); $recursive_array_iterator = new RecursiveArrayIterator($myArray); iterator_apply(new ArrayObject($recursive_array_iterator), 'traverseRecursiveArray', array($recursive_array_iterator)); function traverseRecursiveArray($iterator) { while ($iterator->valid()) { if ($iterator->hasChildren()) { traverseRecursiveArray($iterator->getChildren()); } else { $iterator->offsetSet($iterator->key(), manipulate($iterator->current())); echo $iterator->key() .

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).
