run code in 300+ PHP versions simultaneously
<?php declare(strict_types=1); function foo(int $x): void { echo 'This is fine:', $x, PHP_EOL; } // Good foo(12345); // Bad try { foo(3.1415); } catch (TypeError $ex) { echo $ex->getMessage(), PHP_EOL; } // Also bad, apparently! foo(PHP_INT_MAX + (PHP_INT_MAX >> 1));

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).
