if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');

$auth.SentCode = $MadelineProto->auth->sendCode(['phone_number' => 'string', 'api_id' => int, 'api_hash' => 'string', 'settings' => CodeSettings, ]);
