<?php $array = array( 0 => 'test', 'test' => 'test', ); print('<pre>'); foreach ($array as $k => $value) { if ($k == 'test') { print($value . "\n"); } }

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).
