run code in 300+ PHP versions simultaneously
<?php $jsonReplaces = array("\", "/", "\n", "\t", "\r", "\b", "\f", '"' ); var_dump($jsonReplaces);

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).
