<?php $array1[0] = "zero"; $array1[1] = "one"; $array2[1] = "one"; $array2[2] = "two"; $array2[3] = "three"; print_r(array_merge($array1 + $array2));

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).
