PHP Telegram Sender

Simple PHP library which simplifies the task of sending bot messages using Telegram IM.

Installation

The best way to install the library in your project is by using Composer:

composer require idct/php-telegram-sender

of course you can still manually include all the required files in your project using using statements yet Composer and autoloading is more than suggested.

Usage

Actions are handled via static methods as it is meant to be as simple as possible and at the moment there is no real benfit from instances of the main class.

To use it first add somewhere the use statement:

use IDCT\TelegramSender\TelegramSender;

Then you have few methods available:

• to check if a bot is valid by its bot id:

TelegramSender::checkIfBotIsValid(123123123);

where 123123123 is bot's id.

Returns true or false depending on the fact if bot id is valid.

• you can retrieve basic bot's information using:

TelegramSender::retrieveBotInfo(123123123);

where 123123123 is bot's id.

Returns an instance of BotInfo.

• the main method of the library is sendMessage:

TelegramSender::sendMessage(Bot $bot, Channel $channel, string $message, ParseMode $parseMode = null, bool $disableWebPagePreview = false, bool $disableAudioNotification = false, int $threadId = null);

Messages support HTML and Markdown depending on the $parseMode arguemnt's value.

$channel must be an instance of PublicChannel or PrivateChannel.

Example:

TelegramSender::sendMessage(
    new Bot(123123123, 'AAFKeyoJC6wHmHW85TfUktEMc2x5iz9melE'),
    new PrivateChannel(90808012),
    'my message'
);

Values for the Bot and Channel constructors can be obtained from the Telegram app: check descriptions below.

Method returns an array of elements listed here: https://core.telegram.org/bots/api#message

TODO: Message entity in the library.

How to create a new bot?

1. Contact BotFather user on Telegram

2. Type /newbot to the BotFather and answer all the asked questions.

3. The part which looks like 635092640:AAGfG72lFg0L_Uf8Cfhb5wBi4UFTm7R2lDY are your bot's id and key. The part before : is the id and the part after is the key. So for the example above it would be:

id: 635092640 key: AAGfG72lFg0L_Uf8Cfhb5wBi4UFTm7R2lDY

so you would create an instance of the bot as follows:

$bot = new Bot(635092640, 'AAGfG72lFg0L_Uf8Cfhb5wBi4UFTm7R2lDY');

Where to get the channel's id from?

1. Create a channel using your Telegram client (New channel option in the hamburger menu on the left usually).

2. Add your bot as the admin of the channel.

3. Open https://web.telegram.org/ and sign in using your account.

4. Click on the desired channel. The url in your browser will change.

5. If the url changes to: https://web.telegram.org/#/im?p=c1282543751_17534450962567305630 then 1282543751 is your channel's id. So basically the part between c and _ after ? (in the query string).

6. Use it to create PrivateChannel or PublicChannel instance depending on the visibility of your channel.

...I know it is quite complicated, but at the moment Telegram's API does not expose any method to get bot's channels.

Contribution

In order to contribute open a Pull Request or an Issue. At the moment there are two major points where contribution is more than welcome: support for additional methods of Telegram's API and better unit tests. Handling of the responses: like creating an entity class for the response would be very useful too.
