run code in 300+ PHP versions simultaneously
<?php if (checkdnsrr('gezlev.ru', 'A')) // or use ANY or for other see above link { echo 'Domain exists'; } else { echo 'Domain does not exist'; }

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).
