A Telegram Bot based on the official Telegram Bot API

Table of Contents

Introduction

This is a pure PHP Telegram Bot, fully extensible via plugins. Telegram recently announced official support for a Bot API allowing integrators of all sorts to bring automated interactions to the mobile platform. This Bot aims to provide a platform where one can simply write a plugin and have interactions in a matter of minutes.

The Bot can:

  • retrieve updates with webhook and getUpdates methods.
  • supports all types and methods according to Telegram API (25 May 2016).
  • supports supergroups.
  • handle commands in chat with other bots.
  • manage Channel from the bot admin interface.
  • full support for inline bots.
  • inline keyboard.
  • Messages, InlineQuery and ChosenInlineQuery are stored in the Database.
  • Botan.io integration and database cache system. (new!)
  • Conversation feature

This code is available on Github. Pull requests are welcome.

Instructions

Create your first bot

  1. Message @botfather https://telegram.me/botfather with the following text: /newbot If you don't know how to message by username, click the search field on your Telegram app and type @botfather, where you should be able to initiate a conversation. Be careful not to send it to the wrong contact, because some users has similar usernames to botfather.

    botfather initial conversation

  2. @botfather replies with Alright, a new bot. How are we going to call it? Please choose a name for your bot.

  3. Type whatever name you want for your bot.

  4. @botfather replies with Good. Now let's choose a username for your bot. It must end in `bot`. Like this, for example: TetrisBot or tetris_bot.

  5. Type whatever username you want for your bot, minimum 5 characters, and must end with bot. For example: telesample_bot

  6. @botfather replies with:

    Done! Congratulations on your new bot. You will find it at
    telegram.me/telesample_bot. You can now add a description, about
    section and profile picture for your bot, see /help for a list of
    commands.
    
    Use this token to access the HTTP API:
    123456789:AAG90e14-0f8-40183D-18491dDE
    
    For a description of the Bot API, see this page:
    https://core.telegram.org/bots/api

  9. @botfather replies with Choose a bot to change group messages settings.

  10. Type (or select) @telesample_bot (change to the username you set at step 5 above, but start it with @)

  11. @botfather replies with

    'Enable' - your bot will only receive messages that either start with the '/' symbol or mention the bot by username.
    'Disable' - your bot will receive all messages that people send to groups.
    Current status is: ENABLED
    
  12. Type (or select) Disable to let your bot receive all messages sent to a group. This step is up to you actually.

  13. @botfather replies with Success! The new status is: DISABLED. /help

Require this package with Composer

Install this package through Composer. Edit your project's composer.json file to require longman/telegram-bot.

Create composer.json file

{
    "name": "yourproject/yourproject",
    "type": "project",
    "require": {
        "php": ">=5.5",
        "longman/telegram-bot": "*"
    }
}

and run composer update

or

run this command in your command line:

composer require longman/telegram-bot

Choose how to retrieve Telegram updates

The bot can handle updates with Webhook or getUpdates method:

Webhook getUpdates
Description Telegram sends the updates directly to your host You have to fetch Telegram updates manually
Host with https Required Not required
MySQL Not required Required

Webhook installation

Note: For a more detailed explanation, head over to the example-bot repository and follow the instructions there.

In order to set a Webhook you need a server with HTTPS and composer support. (For a self signed certificate you need to add some extra code)

Create set.php with the following contents:

<?php
// Load composer
require __DIR__ . '/vendor/autoload.php';

$bot_api_key  = 'your:bot_api_key';
$bot_username = 'username_bot';
$hook_url = 'https://your-domain/path/to/hook.php';

try {
    // Create Telegram API object
    $telegram = new Longman\TelegramBot\Telegram($bot_api_key, $bot_username);

    // Set webhook
    $result = $telegram->setWebhook($hook_url);
    if ($result->isOk()) {
        echo $result->getDescription();
    }
} catch (Longman\TelegramBot\Exception\TelegramException $e) {
    // log telegram errors
    // echo $e->getMessage();
}

Open your set.php via the browser to register the webhook with Telegram. You should see Webhook was set.

Now, create hook.php with the following contents:

<?php
// Load composer
require __DIR__ . '/vendor/autoload.php';

$bot_api_key  = 'your:bot_api_key';
$bot_username = 'username_bot';

try {
    // Create Telegram API object
    $telegram = new Longman\TelegramBot\Telegram($bot_api_key, $bot_username);

    // Handle telegram webhook request
    $telegram->handle();
} catch (Longman\TelegramBot\Exception\TelegramException $e) {
    // Silence is golden!
    // log telegram errors
    // echo $e->getMessage();
}

Self Signed Certificate

To upload the certificate, add the certificate path as a parameter in set.php:

$result = $telegram->setWebhook($hook_url, ['certificate' => '/path/to/certificate']);

Unset Webhook

Edit unset.php with your bot credentials and execute it.

getUpdates installation

The MySQL database must be enabled for the getUpdates method!

Create getUpdatesCLI.php with the following contents:

#!/usr/bin/env php
<?php
require __DIR__ . '/vendor/autoload.php';

$bot_api_key  = 'your:bot_api_key';
$bot_username = 'username_bot';
$mysql_credentials = [
   'host'     => 'localhost',
   'user'     => 'dbuser',
   'password' => 'dbpass',
   'database' => 'dbname',
];

try {
    // Create Telegram API object
    $telegram = new Longman\TelegramBot\Telegram($bot_api_key, $bot_username);

    // Enable MySQL
    $telegram->enableMySql($mysql_credentials);

    // Handle telegram getUpdates request
    $telegram->handleGetUpdates();
} catch (Longman\TelegramBot\Exception\TelegramException $e) {
    // log telegram errors
    // echo $e->getMessage();
}

Next, give the file permission to execute:

$ chmod +x getUpdatesCLI.php

Lastly, run it!

$ ./getUpdatesCLI.php

Support

Types

All types are implemented according to Telegram API (20 January 2016).

Inline Query

Full support for inline query according to Telegram API (20 January 2016).

Methods

All methods are implemented according to Telegram API (20 January 2016).

Send Message

Messages longer than 4096 characters are split up into multiple messages.

$result = Request::sendMessage(['chat_id' => $chat_id, 'text' => 'Your utf8 text 😜 ...']);

Send Photo

To send a local photo, add it properly to the $data parameter using the file path:

$data = [
    'chat_id' => $chat_id,
    'photo'   => Request::encodeFile('/path/to/pic.jpg'),
];
$result = Request::sendPhoto($data);

If you know the file_id of a previously uploaded file, just use it directly in the data array:

$data = [
    'chat_id' => $chat_id,
    'photo'   => $file_id,
];
$result = Request::sendPhoto($data);

To send a remote photo, use the direct URL instead:

$data = [
    'chat_id' => $chat_id,
    'photo'   => 'https://example.com/path/to/pic.jpg',
];
$result = Request::sendPhoto($data);

sendAudio, sendDocument, sendSticker, sendVideo, sendVoice and sendVideoNote all work in the same way, just check the API documentation for the exact usage. See the ImageCommand.php for a full example.

Send Chat Action

Request::sendChatAction(['chat_id' => $chat_id, 'action' => 'typing']);

getUserProfilePhoto

Retrieve the user photo, see WhoamiCommand.php for a full example.

getFile and downloadFile

Get the file path and download it, see WhoamiCommand.php for a full example.

Send message to all active chats

To do this you have to enable the MySQL connection. Here's an example of use (check DB::selectChats() for parameter usage):

$results = Request::sendToActiveChats(
    'sendMessage', // Callback function to execute (see Request.php methods)
    ['text' => 'Hey! Check out the new features!!'], // Param to evaluate the request
    [
        'groups'      => true,
        'supergroups' => true,
        'channels'    => false,
        'users'       => true,
    ]
);

You can also broadcast a message to users, from the private chat with your bot. Take a look at the admin commands below.

Utils

MySQL storage (Recommended)

If you want to save messages/users/chats for further usage in commands, create a new database (utf8mb4_unicode_520_ci), import structure.sql and enable MySQL support after object creation and BEFORE handle() method:

$mysql_credentials = [
   'host'     => 'localhost',
   'user'     => 'dbuser',
   'password' => 'dbpass',
   'database' => 'dbname',
];

$telegram->enableMySql($mysql_credentials);

You can set a custom prefix to all the tables while you are enabling MySQL:

$telegram->enableMySql($mysql_credentials, $bot_username . '_');

You can also store inline query and chosen inline query data in the database.

External Database connection

It is possible to provide the library with an external MySQL PDO connection. Here's how to configure it:

$telegram->enableExternalMySql($external_pdo_connection)
//$telegram->enableExternalMySql($external_pdo_connection, $table_prefix)

Channels Support

All methods implemented can be used to manage channels. With admin commands you can manage your channels directly with your bot private chat.

Botan.io integration (Optional)

You can enable the integration using this line in you hook.php:

$telegram->enableBotan('your_token');

Replace your_token with your Botan.io token, check this page to see how to obtain one.

The following actions will be tracked:

  • Commands (shown as Command (/command_name) in the stats
  • Inline Queries, Chosen Inline Results and Callback Queries
  • Messages sent to the bot (or replies in groups)

In order to use the URL shortener you must include the class use Longman\TelegramBot\Botan; and call it like this:

Botan::shortenUrl('https://github.com/php-telegram-bot/core', $user_id);

Shortened URLs are cached in the database (if MySQL storage is enabled).

Commands

Predefined Commands

The bot is able to recognise commands in a chat with multiple bots (/command@mybot).

It can execute commands that get triggered by chat events.

Here's the list:

  • StartCommand.php (A new user starts to use the bot.)

  • NewChatMembersCommand.php (A new member(s) was added to the group, information about them.)

  • LeftChatMemberCommand.php (A member was removed from the group, information about them.)

  • NewChatTitleCommand.php (A chat title was changed to this value.)

  • NewChatPhotoCommand.php (A chat photo was changed to this value.)

  • DeleteChatPhotoCommand.php (Service message: the chat photo was deleted.)

  • GroupChatCreatedCommand.php (Service message: the group has been created.)

  • SupergroupChatCreatedCommand.php (Service message: the supergroup has been created.)

  • ChannelChatCreatedCommand.php (Service message: the channel has been created.)

  • MigrateToChatIdCommand.php (The group has been migrated to a supergroup with the specified identifier.)

  • MigrateFromChatIdCommand.php (The supergroup has been migrated from a group with the specified identifier.)

  • PinnedMessageCommand.php (Specified message was pinned.)

  • GenericmessageCommand.php (Handle any type of message.)

  • GenericCommand.php (Handle commands that don't exist or to use commands as a variable.)

    • Favourite colour? /black, /red
    • Favourite number? /1, /134

Custom Commands

Maybe you would like to develop your own commands. There is a guide to help you create your own commands.

Also, be sure to have a look at the example commands to learn more about custom commands and how they work.

Commands Configuration

With this method you can set some command specific parameters, for example:

// Google geocode/timezone API key for /date command
$telegram->setCommandConfig('date', ['google_api_key' => 'your_google_api_key_here']);

// OpenWeatherMap API key for /weather command
$telegram->setCommandConfig('weather', ['owm_api_key' => 'your_owm_api_key_here']);

Admin Commands

Enabling this feature, the bot admin can perform some super user commands like:

  • List all the chats started with the bot /chats
  • Clean up old database entries /cleanup
  • Show debug information about the bot /debug
  • Send message to all chats /sendtoall
  • Post any content to your channels /sendtochannel
  • Inspect a user or a chat with /whois

Take a look at all default admin commands stored in the src/Commands/AdminCommands/ folder.

Set Admins

You can specify one or more admins with this option:

// Single admin
$telegram->enableAdmin(your_telegram_user_id);

// Multiple admins
$telegram->enableAdmins([your_telegram_user_id, other_telegram_user_id]);

Telegram user id can be retrieved with the /whoami command.

Channel Administration

To enable this feature follow these steps:

  • Add your bot as channel administrator, this can be done with any Telegram client.
  • Enable admin interface for your user as explained in the admin section above.
  • Enter your channel name as a parameter for the /sendtochannel command:
$telegram->setCommandConfig('sendtochannel', ['your_channel' => ['@type_here_your_channel']]);
  • If you want to manage more channels:
$telegram->setCommandConfig('sendtochannel', ['your_channel' => ['@type_here_your_channel', '@type_here_another_channel', '@and_so_on']]);
  • Enjoy!

Upload and Download directory path

To use the Upload and Download functionality, you need to set the paths with:

$telegram->setDownloadPath('/your/path/Download');
$telegram->setUploadPath('/your/path/Upload');
