Handling updates (new messages)

Update handling can be done in different ways:

Async Event driven

class EventHandler extends \danog\MadelineProto\EventHandler
{
    public function __construct($MadelineProto)
    {
        parent::__construct($MadelineProto);
    }
    public function onAny($update)
    {
        \danog\MadelineProto\Logger::log("Received an update of type ".$update['_']);
    }
    public function onUpdateNewChannelMessage($update)
    {
        yield $this->onUpdateNewMessage($update);
    }
    public function onUpdateNewMessage($update)
    {
        if (isset($update['message']['out']) && $update['message']['out']) {
            return;
        }
        $res = json_encode($update, JSON_PRETTY_PRINT);
        if ($res == '') {
            $res = var_export($update, true);
        }

        try {
            yield $this->messages->sendMessage(['peer' => $update, 'message' => $res, 'reply_to_msg_id' => $update['message']['id']]);
        } catch (\danog\MadelineProto\RPCErrorException $e) {
            yield $this->messages->sendMessage(['peer' => '@danogentili', 'message' => $e]);
        }

        try {
            if (isset($update['message']['media']) && ($update['message']['media']['_'] == 'messageMediaPhoto' || $update['message']['media']['_'] == 'messageMediaDocument')) {
                $time = microtime(true);
                $file = yield $this->download_to_dir($update, '/tmp');
                yield $this->messages->sendMessage(['peer' => $update, 'message' => 'Downloaded to '.$file.' in '.(microtime(true) - $time).' seconds', 'reply_to_msg_id' => $update['message']['id']]);
            }
        } catch (\danog\MadelineProto\RPCErrorException $e) {
            yield $this->messages->sendMessage(['peer' => '@danogentili', 'message' => $e]);
        }
    }
}


$MadelineProto = new \danog\MadelineProto\API('bot.madeline');
$MadelineProto->async(true);
$MadelineProto->loop(function () use ($MadelineProto) {
    yield $MadelineProto->start();
    yield $MadelineProto->setEventHandler('\EventHandler');
});
$MadelineProto->loop();

This will create an event handler class EventHandler, create a MadelineProto session, and set the event handler class to our newly created event handler.

This yield syntax might be new to you, even if you already used MadelineProto in the past.
It's a new syntax to allow async parallel processing of updates and HUGE speed improvements.
It was recently introduced in MadelineProto, here's a full explanation.
If your code still relies on the old synchronous behaviour, it's still supported, but I HIGHLY recommend you switch to the new async syntax: it's super easy, just add a yield in front of method calls!

When an Update is received, the corresponding onUpdateType event handler method is called.

To get a list of all possible update types, click here.

If such a method does not exist, the onAny event handler method is called.
If the onAny event handler method does not exist, the update is ignored.
The onLoop method is not recommended anymore, use AMPHP's repeat or MadelineProto's async loop API to schedule actions in a cron-like manner.

To access the $MadelineProto instance inside of the event handler, simply access $this:

$this->messages->sendMessage(['peer' => '@danogentili', 'message' => 'hi']);

If you intend to use your own constructor in the event handler, make sure to call the parent construtor with the only parameter provided to your constructor.

The update handling loop is started by the $MadelineProto->loop() method, and it will automatically restart the script if execution time runs out.

To break out of the loop just call die();, or throw an exception from within (make sure to catch it outside, in the $MadelineProto->loop() call).

Async Combined event driven

class EventHandler extends \danog\MadelineProto\CombinedEventHandler
{
    public function __construct($CombinedMadelineProto)
    {
        parent::__construct($CombinedMadelineProto);
    }
    public function onAny($update, $session)
    {
        \danog\MadelineProto\Logger::log("Received an update of type ".$update['_']);
    }
    public function onLoop()
    {
        \danog\MadelineProto\Logger::log("Working...");
    }
    public function onUpdateNewChannelMessage($update, $session)
    {
        yield $this->onUpdateNewMessage($update, $session);
    }
    public function onUpdateNewMessage($update, $session)
    {
        if (isset($update['message']['out']) && $update['message']['out']) {
            return;
        }
        $res = json_encode($update, JSON_PRETTY_PRINT);
        if ($res == '') {
            $res = var_export($update, true);
        }

        try {
            yield $this->{$session}->messages->sendMessage(['peer' => $update, 'message' => $res, 'reply_to_msg_id' => $update['message']['id']]);
        } catch (\danog\MadelineProto\RPCErrorException $e) {
            yield $this->{$session}->messages->sendMessage(['peer' => '@danogentili', 'message' => $e]);
        }

        try {
            if (isset($update['message']['media']) && ($update['message']['media']['_'] == 'messageMediaPhoto' || $update['message']['media']['_'] == 'messageMediaDocument')) {
                $time = microtime(true);
                $file = yield $this->{$session}->download_to_dir($update, '/tmp');
                yield $this->{$session}->messages->sendMessage(['peer' => $update, 'message' => 'Downloaded to '.$file.' in '.(microtime(true) - $time).' seconds', 'reply_to_msg_id' => $update['message']['id']]);
            }
        } catch (\danog\MadelineProto\RPCErrorException $e) {
            yield $this->{$session}->messages->sendMessage(['peer' => '@danogentili', 'message' => $e]);
        }
    }
}

$settings = [];
$CombinedMadelineProto = new \danog\MadelineProto\CombinedAPI('combined_session.madeline', ['bot.madeline' => $settings, 'user.madeline' => $settings, 'user2.madeline' => $settings]);
$CombinedMadelineProto->async(true);
$CombinedMadelineProto->loop(function () use ($CombinedMadelineProto) {
    $res = [];
    foreach ([
        'bot.madeline' => 'Bot Login',
        'user.madeline' => 'Userbot login',
        'user2.madeline' => 'Userbot login (2)'
    ] as $session => $message) {
        \danog\MadelineProto\Logger::log($message, \danog\MadelineProto\Logger::WARNING);
        $res []= $CombinedMadelineProto->instances[$session]->start();
    }
    yield $CombinedMadelineProto->all($res);
    yield $CombinedMadelineProto->setEventHandler('\EventHandler');
}
$CombinedMadelineProto->loop();

This will create an event handler class EventHandler, create a combined MadelineProto session with session files bot.madeline, user.madeline, user2.madeline, and set the event handler class to our newly created event handler.

When an Update is received, the corresponding onUpdateType event handler method is called.

To get a list of all possible update types, click here.

If such a method does not exist, the onAny event handler method is called.
If the onAny event handler method does not exist, the update is ignored.
The first paramter of the event handler method will always be the Update, the second parameter will always be the session name.

The onLoop method is not recommended anymore, use AMPHP's repeat or MadelineProto's async loop API to schedule actions in a cron-like manner.

To access the $MadelineProto instance of the account that sent the update, from inside of the event handler, simply access $this->{$session_name} ($session_name is the second parameter value of the event handler method, or just the session filename):

$this->{$session_name}->messages->sendMessage(['peer' => '@danogentili', 'message' => 'hi']);
$this->{'user2.madeline'}->messages->sendMessage(['peer' => '@danogentili', 'message' => 'hi2']);

If you intend to use your own constructor in the event handler, make sure to call the parent construtor with the only parameter provided to your constructor.

If you need to use the __sleep function, make sure it is called __magic_sleep, instead.

The update handling loop is started by the $MadelineProto->loop() method, and it will automatically restart the script if execution time runs out.

To break out of the loop just call die();, or throw an exception from within (make sure to catch it outside, in the $MadelineProto->loop() call).

Async callback

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

$MadelineProto->start();
$MadelineProto->setCallback(function ($update) use ($MadelineProto) {

    if (isset($update['message']['out']) && $update['message']['out']) {
        return;
    }
    $res = json_encode($update, JSON_PRETTY_PRINT);
    if ($res == '') {
        $res = var_export($update, true);
    }

    try {
        yield $MadelineProto->messages->sendMessage(['peer' => $update, 'message' => $res, 'reply_to_msg_id' => $update['message']['id']]);
    } catch (\danog\MadelineProto\RPCErrorException $e) {
        yield $MadelineProto->messages->sendMessage(['peer' => '@danogentili', 'message' => $e]);
    }
});
$MadelineProto->async(true);
$MadelineProto->loop();

When an Update is received, the provided callback function is called.

The update handling loop is started by the $MadelineProto->loop() method, and it will automatically restart the script if execution time runs out.

Noop

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

$MadelineProto->start();
$MadelineProto->setNoop();

When an Update is received, nothing is done. This is useful if you need to populate the internal peer database with peers to avoid This peer is not present in the internal peer database errors, but don't need to handle updates.
This is the default.

Fetch all updates from the beginning

You can use the resetUpdateState method to reset the update state and fetch all updates from the beginning:

$MadelineProto->resetUpdateState();
