<?php $default = [ 'case' => 'default', 'autre' => 'autre defaut' ]; $override = ['case' => 'overridden']; var_dump(array_merge($override, $default));

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).
