run code in 300+ PHP versions simultaneously
<?php function ping_pong() { for ($i = 1; $i <= 10; $i++) { $val = (yield $i) // if ( !== null) // { echo 'ping: ' . $val . PHP_EOL; // } } } $generator = ping_pong(); foreach ($generator as $value) { echo 'pong: ' . $generator->send($value) . PHP_EOL; }

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).
