run code in 300+ PHP versions simultaneously
<?php declare(strict_types = 1); /** * @param array{a?:array{b:bool}} $options */ function f(array $options): bool { if (isset($options['a']['b'])) { return true; } return false; } /** * @param array{a?:array{b:bool}} $options */ function g(array $options): bool { if (isset($options['a'], $options['a']['b'])) { return true; } return false; } var_dump(f([]));

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).
