run code in 300+ PHP versions simultaneously
<?php echo 'a', 'b', 'c'; // abc echo ('a' . 'b' . 'c'); // abc print('a' . 'b' . 'c'); // abc ?>

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).
