<?php $array = [ 'foo' => [ 'bar' => [ 'baz' => 'bat'] ] ]; $obj = new ArrayObject($array); $cb = function($obj) { $obj['foo']['bar'] = 'bazbat'; }; print_r($obj); $cb($obj); print_r($obj); print_r((array)$obj);

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).
