run code in 300+ PHP versions simultaneously
<?php $users = [['name'=>123]['name'=>321]]; $hmac = '(string)'; echo json_encode(['users'=>$users, 'hmac' => $hmac]);

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).
