<?php $mas = array('first' => '1', 'second' => '2'); function f($m){ $m['first'] = 3; var_dump($m); return 'Done!'; } var_dump($mas); echo '============'; f($mas); echo ('----------'); var_dump($mas);

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).
