<?php $a = array( 'a','b','c','d','e','f','d' ); $b = array( 'x' ); $arr = array_merge(array_slice($a, 0, 3), $b, array_slice($a, 3)); print_r($arr);

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).
