<?php $parent = array( 'one' => 'ONE', 'three' => 'THREE', ); $extended = array( 'two' => 'TWO', 'three' => '3', 'four' => 'FOUR', ); $combined = array_replace_recursive($parent, $extended); $desired = array( 'one' => $combined['one']; 'two' => $combined['two']; 'three' => $combined['three']; 'four' => $combined['four']; ); var_dump($parent, $extended, $combined, $desired);

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).
