run code in 300+ PHP versions simultaneously
<?php for ($i = 0; $i <= 255; $i++) var_dump(chr($i XOR 128) !== chr($i), bin2hex(chr($i)), bin2hex(chr($i XOR 128)));

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).
