<?php $a = ['0' => '0A', '1' => '1A', '2' => '2A']; $b = ['0' => '0B', '4' => '4B', '2' => '2B']; $c = ['0' => '0C', '3' => '3C', '2' => '2C']; $options = $c + $b; print_r($options);

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).
