$MadelineProto = new \danog\MadelineProto\API();
if (isset($token)) {
    $this->bot_login($token);
}
if (isset($number)) {
    $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);
}

$updates_ChannelDifference = $MadelineProto->updates->getChannelDifference(['force' => Bool, 'channel' => InputChannel, 'filter' => ChannelMessagesFilter, 'pts' => int, 'limit' => int, ]);
```

Or, if you're into Lua:

```
updates_ChannelDifference = updates.getChannelDifference({force=Bool, channel=InputChannel, filter=ChannelMessagesFilter, pts=int, limit=int, })
```
