<?php $a = array( 'a' => 'Bonjour', 'b' => 'Aurev', ); $b = array( 'a' => 'A', 'b' => 'B', 'c' => 'Tcho', ); $c = $a + $b; //$c = array_merge($a, $b); var_dump($c);

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).
