<?php $wl = array( 'word2' => 'link2.com', 'word3' => 'link3.com', 'word4' => 'link4.com', 'word5' => 'link5.com' ); shuffle($wl); $newarr = array_keys($wl); print_r($newarr);

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).
