run code in 300+ PHP versions simultaneously
<?php $str = "\\\40"; $strip_hex = '#[\\\]+#i'; //$clean = preg_replace($strip_hex,'',$str); echo $str;

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).
