run code in 300+ PHP versions simultaneously
<?php for ($i = 0; $i < 1000000; $i++) { $random = array_rand(range(1, 49), 6); if (count(array_unique($random)) !== 6) { echo "BREAK"; } } echo count($random);

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).
