run code in 300+ PHP versions simultaneously
<?php $string = 'test' . chr(0) . "\n" . 'Test' . "\r\n"; $result = mb_ereg_replace('(\0)|(\r)|(\n)', '\\\1', $string); var_dump($result);

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).
