### MadelineProto Example ([now async for huge speed and parallelism!](https://docs.madelineproto.xyz/docs/ASYNC.html)):


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

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

$auth.SentCode = $MadelineProto->auth->sendCode(['allow_flashcall' => Bool, 'phone_number' => 'string', 'current_number' => Bool, 'api_id' => int, 'api_hash' => 'string', ]);
```

Or, if you're into Lua:

```lua
auth.SentCode = auth.sendCode({allow_flashcall=Bool, phone_number='string', current_number=Bool, api_id=int, api_hash='string', })
