```
$MadelineProto = new \danog\MadelineProto\API();
if (isset($token)) { // Login as a bot
    $this->bot_login($token);
}
if (isset($number)) { // Login as a user
    $sentCode = $MadelineProto->phone_login($number);
    echo 'Enter the code you received: ';
    $code = '';
    for ($x = 0; $x < $sentCode['type']['length']; $x++) {
        $code .= fgetc(STDIN);
    }
    $MadelineProto->complete_phone_login($code);
}

$Document = $MadelineProto->messages->getDocumentByHash(['sha256' => bytes, 'size' => int, 'mime_type' => string, ]);
```

```
Document = messages.getDocumentByHash({sha256=bytes, size=int, mime_type=string, })
