MadelineProto
Created by Daniil Gentili, licensed under AGPLv3.
Logo created by Matthew Hesketh (thanks again!).
PHP implementation of MTProto, based on telepy.
This project can run on PHP 7 and HHVM, only 64 bit systems are supported ATM.
Also note that MadelineProto will perform better if python and a big math extension like gmp or bcmath are installed.
This project is in beta state.
The MadelineProto API documentation can be found here (layer 62).
The MadelineProto API documentation (mtproto tl scheme) can be found here.
The MadelineProto API documentations (old layers) can be found here.
Acknowledgements
While writing this client, I looked at many projects for inspiration and help. Here's the full list:
Thanks to the devs that contributed to these projects, MadelineProto is now an easy, well-written and complete MTProto client.
Usage
Installation
git clone https://github.com/danog/MadelineProto
cd MadelineProto
Now copy .env.example to .env, edit the its values, read the docs and take a look at tests/testing.php, bot.php.
Dependencies
This project depends on PHPStruct, phpseclib
To install dependencies install composer and run:
composer update
In the cloned repo.
Instantiation
$MadelineProto = new \danog\MadelineProto\API();
Settings
The constructor accepts an optional parameter, which is the settings array. This array contains some other arrays, which are the settings for a specific MadelineProto function.
See here for the default values for the settings arrays and explanations for every setting.
You can provide part of any subsetting array, that way the remaining arrays will be automagically set to default and undefined values of specified subsetting arrays will be set to the default values.
Example:
$settings = [
'authorization' => [ // Authorization settings
'default_temp_auth_key_expires_in' => 86400, // a day
]
]
Becomes:
$settings = [
'authorization' => [ // Authorization settings
'default_temp_auth_key_expires_in' => 86400,
'rsa_key' => '-----BEGIN RSA PUBLIC KEY-----

-----END RSA PUBLIC KEY-----',
]
// The remaining subsetting arrays are the set to default
]
Note that only settings arrays or values of a settings array will be set to default.
The settings array can be accessed in the instantiated class like this:
$MadelineProto = new \danog\MadelineProto\API();
var_dump($MadelineProto->get_settings());
The settings array can be modified in the instantiated class like this:
$MadelineProto = new \danog\MadelineProto\API();
$settings = $MadelineProto->get_settings();
// Make changes to $settings
$MadelineProto->update_settings($settings);
Handling updates
When an update is received, the update callback function (see settings) is called. By default, the get_updates_update_handler MadelineProto method is called. This method stores all incoming updates into an array (its size limit is specified by the updates_array_limit parameter in the settings) and can be fetched by running the get_updates method.
This method accepts an array of options as the first parameter, and returns an array of updates (an array containing the update id and an object of type Update). Example:
$MadelineProto = new \danog\MadelineProto\API();
// Login or deserialize
$offset = 0;
while (true) {
$updates = $MadelineProto->API->get_updates(['offset' => $offset, 'limit' => 50, 'timeout' => 1]); // Just like in the bot API, you can specify an offset, a limit and a timeout
foreach ($updates as $update) {
$offset = $update['update_id']; // Just like in the bot API, the offset must be set to the last update_id
// Parse $update['update'], that is an object of type Update
}
var_dump($updates);
}

To specify a custom callback change the correct value in the settings. The specified callable must accept one parameter for the update.
Uploading and downloading files
MadelineProto provides wrapper methods to upload and download files.
Every method described in this section accepts a last optional paramater with a callable function that will be called during the upload/download using the first parameter to pass a floating point number indicating the upload/download status in percentage.
The upload method returns an InputFile object that must be used to generate an InputMedia object, that can be later sent using the sendmedia method.
$inputFile = $MadelineProto->upload('file', 'optional new file name.ext');
// Generate an inputMedia object and store it in $inputMedia, see tests/testing.php
$MadelineProto->messages->sendMedia(['peer' => '@pwrtelegramgroup', 'media' => $inputMedia]);
See tests/testing.php for more examples.
There are multiple download methods that allow you to download a file to a directory, to a file or to a stream.
The first parameter of these functions must always be a messageMediaPhoto or a messageMediaDocument object. These objects are usually received in updates, see bot.php for examples
$output_file_name = $MadelineProto->download_to_dir($message_media, '/tmp/dldir');
$custom_output_file_name = $MadelineProto->download_to_file($message_media, '/tmp/dldir/customname.ext');
$stream = fopen('php://output', 'w'); // Stream to browser like with echo
$MadelineProto->download_to_stream($message_media, $stream, $cb, $offset, $endoffset); // offset and endoffset are optional parameters that specify the byte from which to start downloading and the byte where to stop downloading (the latter non-inclusive), if not specified default to 0 and the size of the file
Calling mtproto methods and available wrappers
The API documentation can be found here.
To call an MTProto method simply call it as if it is a method of the API class, substitute namespace sepators (.) with -> if needed.
Also, an object of type User, InputUser, Chat, InputChannel, Peer or InputPeer must be provided as a parameter to a method, you can substitute it with the user/group/channel's username or bot API id.
$MadelineProto = new \danog\MadelineProto\API();
$checkedPhone = $MadelineProto->auth->checkPhone( // auth.checkPhone becomes auth->checkPhone
[
'phone_number' => '3993838383', // Random invalid number, note that there should be no +
]
);
$ping = $MadelineProto->ping([3]); // parameter names can be omitted as long as the order specified by the TL scheme is respected
$message = "Hey! I'm sending this message with MadelineProto!";
$sentMessage = $MadelineProto->messages->sendMessage(['peer' => '@danogentili', 'message' => $message]);
var_dump($sentMessage);
The API class also provides some wrapper methods for logging in as a bot or as a normal user, and for getting inputPeer constructors to use in sendMessage and other methods:
$sentCode = $MadelineProto->phone_login($number); // Send code
var_dump($sentCode);
echo 'Enter the code you received: ';
$code = '';
for ($x = 0; $x < $sentCode['type']['length']; $x++) {
$code .= fgetc(STDIN);
}
$authorization = $MadelineProto->complete_phone_login($code); // Complete authorization
var_dump($authorization);
$authorization = $MadelineProto->bot_login($token); // Note that every time you login as a bot or as a user MadelineProto will logout first, so now MadelineProto is logged in as the bot with token $token, not as the user with number $number
var_dump($authorization);
See tests/testing.php for more examples.
Note that when you login as a bot, MadelineProto also logins using the PWRTelegram API, to allow persistant storage of peers, even after a logout and another login.
Storing sessions
An istance of MadelineProto can be safely serialized or unserialized. To serialize MadelineProto to a file, usage of the \danog\MadelineProto\Serialization class is recommended:
$MadelineProto = \danog\MadelineProto\Serialization::deserialize('session.madeline');
// Do stuff
\danog\MadelineProto\Serialization::serialize('session.madeline', $MadelineProto);
That class serializes only if the $MadelineProto->API->should_serialize boolean is set to true.
The same operation should be done when serializing to another destination manually, to avoid conflicts with other PHP scripts that are trying to serialize another instance of the class.
Exceptions
MadelineProto can throw three different exceptions:
-
\danog\MadelineProto\Exception - Default exception, thrown when a php error occures and in a lot of other cases
-
\danog\MadelineProto\RPCErrorException - Thrown when an RPC error occurres (an error received via the mtproto API)
-
\danog\MadelineProto\TL\Exception - Thrown on TL serialization/deserialization errors
-
\danog\MadelineProto\NothingInTheSocketException - Thrown if no data can be read from the TCP socket

MessageHandler - Handles sending and receiving of mtproto messages (packs TL serialized data with message id, auth key id and encrypts it with Crypt if needed, adds them to the arrays of incoming and outgoing messages)
MsgIdHandler - Handles message ids (checks if they are valid, adds them to the arrays of incoming and outgoing messages)
