run code in 300+ PHP versions simultaneously
<?php $text = 'My Name ## is #P_NAM3# and \r\n I am #P_AG2# years old'; //$r = '#([^#]+)#'; //$r = '#[(?<name>\S+)\]#'; $r = '#(.*?)#'; //$r = '#\w*#'; preg_match_all('/'.$r.'/m', $text, $m); var_dump($m);

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).
