<?php $test = array( array('a' => 'testA', 'b' => 'testB'), array('a' =>'testC', 'b' => 'testD') ); $key = array_keys($test, array('a' => 'testA', 'b' => 'testB')); print_r($test[$key[0]]);

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).
