<?php $arr1 = array('bundle1' => ['1'], 'bundle2' => ['2']); $arr2 = array('bundle2' => ['3'], 'bundle1' => ['4']); var_dump(array_merge($arr1, $arr2)); var_dump($arr1 + $arr2);

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).
