<?php $a = array(array(1),2,3); $b = array(1,2,3); $f = array(2,3,4); $c = array_merge($a, $b, $f); var_dump($c); $d = array_unique(array(array(1,2,3))); var_dump($d);

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).
