<?php $data = array( 'field1' => 1, 'field2' => 2, 'field3' => 3, 'field4' => 4 ); $filter = array('field2', 'field3'); $filtered = array_intersect_key($data, array_flip($filter)); var_dump($filtered);

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).
