<?php $a = array( "one" => 1, "two" => array(2), "tres" => array ( 1,2) ); $b = array( "one" => 1, "two" => 1, "tres" => 1 ); array_intersect_key( $a, $b );

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).
