This project can run on PHP 7 and HHVM, both 32 bit and 64 bit systems are supported. You must also install the mbstring, curl extensions and the PHP Lua extension if you want to use the lua binding.
If you have some questions about the usage of the methods of this library, you can join the [support group](https://telegram.me/pwrtelegramgroup) or contact [@danogentili](https://telegram.me/danogentili).
But first, please read this WHOLE page very carefully, follow all links to external documentation, and read all examples in the repo (bot.php, bots/, tests/testing.php).
A very important page you must read is the [API documentation](https://daniil.it/MadelineProto/API_docs/): if it's the first time you see a link to that page it means you didn't read the documentation carefully.
I can offer support, however, when it comes to MadelineProto bugs or problems in the documentation. I will not write code for you for free, however you can hire me to do that if you want (my rate is 50$ per hour); you can also buy an easy to use, customized MadelineProto base for only 30$.
If you're selling a MadelineProto base too, you really should consider donating at least 20% of the price of the base: [this is my PayPal](https://paypal.me/danog).
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](https://github.com/danog/MadelineProto/blob/master/src/danog/MadelineProto/MTProto.php#L232) 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.
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.
IMPORTANT Note that you should turn off update handling if you don't plan to use it because the default get_updates update handling stores updates in an array inside the MadelineProto class, without deleting old ones unless they are read using get_updates. This will eventually fill up the RAM of your server if you don't disable updates or read them using get_updates.
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](https://daniil.it/MadelineProto/API_docs/types/Update.html)). Example:
$updates = $MadelineProto->API->get_updates(['offset' => $offset, 'limit' => 50, 'timeout' => 1]); // Just like in the bot API, you can specify an offset, a limit and a timeout
Every method described in this section accepts a last optional paramater with a callable function that will be called during the upload/download using the first parameter to pass a floating point number indicating the upload/download status in percentage.
The upload method returns an [InputFile](https://daniil.it/MadelineProto/API_docs/types/InputFile.html) object that must be used to generate an [InputMedia](https://daniil.it/MadelineProto/API_docs/types/InputMedia.html) object, that can be later sent using the [sendmedia method](https://daniil.it/MadelineProto/API_docs/methods/messages_sendMedia.html).
The `upload_encrypted` method returns an [InputEncryptedFile](https://daniil.it/MadelineProto/API_docs/types/InputEncryptedFile.html) object that must be used to generate an [EncryptedMessage](https://daniil.it/MadelineProto/API_docs/types/EncryptedMessage.html) object, that can be later sent using the [sendEncryptedFile method](https://daniil.it/MadelineProto/API_docs/methods/messages_sendEncryptedFile.html).
To convert the result of sendMedia to a bot API file id select the messageMedia object from the output of the method and pass it to `$MadelineProto->API->MTProto_to_botAPI()`.
The first parameter of these functions must always be either a [messageMediaPhoto](https://daniil.it/MadelineProto/API_docs/constructors/messageMediaPhoto.html) or a [messageMediaDocument](https://daniil.it/MadelineProto/API_docs/constructors/messageMediaDocument.html) object, an [EncryptedMessage](https://daniil.it/MadelineProto/API_docs/types/EncryptedMessage.html) or a bot API file id. These objects are usually received in updates, see `bot.php` for examples
$MadelineProto->download_to_stream($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
`request_secret_chat` requests a secret secret chat to the [InputUser](https://daniil.it/MadelineProto/API_docs/types/InputUser.html) specified, and returns a number that can be used instead of an [InputEncryptedChat](https://daniil.it/MadelineProto/API_docs/constructors/inputEncryptedChat.html).
Secret chats are accepted or refused automatically, based on a value in the settings array (by default MadelineProto is set to accept all secret chats).
Before sending any message, you must check if the secret chat was accepted by the other client with the following method:
Returns 0 if the chat cannot be found in the local database, 1 if the chat was requested but not yet accepted, and 2 if it is a valid accepted secret chat.
To send messages/files/service messages, simply use the sendEncrypted methods with objects that use the same layer used by the other client (specified by the number after the underscore in decryptedMessage object names, to obtain the layer that must be used for a secret chat use the following wrapper method).
'created' => time(), // When was this chat created
'rekeying' => [0] // Info for rekeying
];
*/
```
This method gets info about a certain chat.
### Lua binding
The lua binding makes use of the Lua php extension.
When istantiating the `\danog\MadelineProto\Lua` class, the first parameter provided to the constructor must be the path to the lua script, and the second parameter a logged in instance of MadelineProto.
The class is basically a wrapper for the lua environment, so by setting an attribute you're setting a variable in the Lua environment, by reading an attribute you're reading a variable from the lua environment, and by calling a function you're actually calling a Lua function you declared in the script.
By assigning a callable to an attribute, you're actually assigning a new function in the lua environment that once called, will call the php callable.
Passing lua callables to a parameter of a PHP callable will throw an exception due to a bug in the PHP lua extension that I gotta fix (so passing the usual cb and cb_extra parameters to the td-cli wrappers isn't yet possible).
All MadelineProto wrapper methods (for example upload, download, upload_encrypted, get_self, and others) are imported in the Lua environment, as well as all MTProto wrappers (see the API docs for more info).
td-cli wrappers are also present: you can use the tdcli_function in lua and pass mtproto updates to the tdcli_update_callback via PHP, they will be automatically converted to/from td objects. Please note that the object conversion is not complete, feel free to contribute to the conversion module in `src/danog/MadelineProto/Conversion/TD.php`.
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.
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:
$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 $number
Methods that allow sending message entities (messages.sendMessage for example) also have an additional parse_mode parameter that enables or disables html/markdown parsing of the message to be sent. See the method-specific documentation for more info.
To convert the results of methods to bot API objects you must provide a second parameter to method wrappers, containing an array with the `botAPI` key set to true.
To disable fetching the result of a method, the array that must be provided as second parameter to method wrapper must have the `noResponse` key set to true.
Note that when you login as a bot, MadelineProto also logins using the [PWRTelegram](https://pwrtelegram.xyz) API, to allow persistant storage of peers, even after a logout and another login.
An istance of MadelineProto can be safely serialized or unserialized. To serialize MadelineProto to a file, usage of the `\danog\MadelineProto\Serialization` class is recommended:
That class serializes only if the `$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.
