PHP Telegram Bot Manager

This project builds on top of PHP Telegram Bot and as such, depends on it!

The main purpose of this mini-library is to make the interaction between your webserver and Telegram easier. I strongly suggest your read the PHP Telegram Bot instructions first, to understand what this library does exactly.

Installation and usage is pretty straight forward:

Require this package with Composer

Either run this command in your command line:

composer require php-telegram-bot/telegram-bot-manager:^1.4

or

For existing Composer projects, edit your project's composer.json file to require php-telegram-bot/telegram-bot-manager:

"require": {
    "php-telegram-bot/telegram-bot-manager": "^1.4"
}

and then run composer update

NOTE: This will automatically also install PHP Telegram Bot into your project (if it isn't already).

Advanced: Due to the fact that the core library is not a stable version yet, this project is partly locked to the core version, to ensure reliable functioning.

It is possible however, to override the core version that this library requires:

"require": {
    "php-telegram-bot/telegram-bot-manager": "^1.4",
    "longman/telegram-bot": "dev-develop as 0.59"
}

This example will pull the develop version of the core library, making it appear to be version 0.57, which then satisfies the requirement.

Performing actions

What use would this library be if you couldn't perform any actions?!

There are a few parameters available to get things rolling:

Parameter	Description
s	secret: This is a special secret value defined in the main manager.php file.
	This parameter is required to call the script via browser!
a	action: The actual action to perform. (handle (default), webhookinfo, cron, set, unset, reset)
	handle executes the getUpdates method; webhookinfo to get result from getWebhookInfo, cron executes cron commands; set / unset / reset the webhook.
l	loop: Number of seconds to loop the script for (used for getUpdates method).
	This would be used mainly via CLI, to continually get updates for a certain period.
i	interval: Number of seconds to wait between getUpdates requests (used for getUpdates method, default is 2).
	This would be used mainly via CLI, to continually get updates for a certain period, every i seconds.
g	group: Commands group for cron (only used together with cron action, default group is default).
	Define which group of commands to execute via cron. Can be a comma separated list of groups.

via browser

Simply point your browser to the manager.php file with the necessary GET parameters:

• http://example.com/manager.php?s=<secret>&a=<action>&l=<loop>&i=<interval>

Webhook

Set, unset and reset the webhook:

• http://example.com/manager.php?s=super_secret&a=set
• http://example.com/manager.php?s=super_secret&a=unset
• http://example.com/manager.php?s=super_secret&a=reset (unset & set combined)

getUpdates

Handle updates once:

• http://example.com/manager.php?s=super_secret&a=handle or simply
• http://example.com/manager.php?s=super_secret (handle action is the default)

Handle updates for 30 seconds, fetching every 5 seconds:

• http://example.com/manager.php?s=super_secret&l=30&i=5

cron

Execute commands via cron:

• http://example.com/manager.php?s=super_secret&a=cron&g=maintenance or multiple groups
• http://example.com/manager.php?s=super_secret&a=cron&g=maintenance,cleanup

via CLI

When using CLI, the secret is not necessary (since it could just be read from the file itself).

Call the manager.php file directly using php and pass the parameters:

• $ php manager.php a=<action> l=<loop> i=<interval>

Webhook

Set, unset and reset the webhook:

• $ php manager.php a=set
• $ php manager.php a=unset
• $ php manager.php a=reset (unset & set combined)

getUpdates

Handle updates once:

• $ php manager.php a=handle or simply
• $ php manager.php (handle action is the default)

Handle updates for 30 seconds, fetching every 5 seconds:

• $ php manager.php l=30 i=5

cron

Execute commands via cron:

• $ php manager.php a=cron g=maintenance or multiple groups
• $ php manager.php a=cron g=maintenance,cleanup

Create the manager PHP file

You can name this file whatever you like, it just has to be somewhere inside your PHP project (preferably in the root folder to make things easier). (Let's assume our file is called manager.php)

Let's start off with a simple example that uses the webhook method:

<?php

use TelegramBot\TelegramBotManager\BotManager;

// Load composer.
require_once __DIR__ . '/vendor/autoload.php';

try {
    $bot = new BotManager([
        // Vitals!
        'api_key'      => '12345:my_api_key',

        // Extras.
        'bot_username' => 'my_own_bot',
        'secret'       => 'super_secret',
        'webhook'      => [
            'url' => 'https://example.com/manager.php',
        ]
    ]);
    $bot->run();
} catch (\Exception $e) {
    echo $e->getMessage() . PHP_EOL;
}

Set vital bot parameters

The only vital parameter is the API key:

$bot = new BotManager([
    // (string) Bot API key provided by @BotFather.
    'api_key' => '12345:my_api_key',
    ...
]);

Set extra bot parameters

Apart from the necessary API key, the bot can be easily configured using extra parameters.

Set the webhook? Enable admins? Add custom command paths? Set up logging?

All no problem!

The secret is a user-defined key that is required to execute any of the library's features via webhook. Best make it long, random and very unique!

For 84 random characters:

• If you have pwgen installed, just execute pwgen 84 1 and copy the output.
• If you have openssl installed, use openssl rand -hex 84.
• Or just go here and put all the output onto a single line.

(You get 2 guesses why 84 is a good number 😉)

Below is a complete list of all available extra parameters.

$bot = new BotManager([
    ...
    // (string) Bot username that was defined when creating the bot.
    'bot_username'     => 'my_own_bot',

            'maintenance' => [

                '/log_rotate',
                '/message_admins Maintenance completed',
            ],
        ],
    ],

    // (string) Override the custom input of your bot (mostly for testing purposes!).
    'custom_input'     => '{"some":"raw", "json":"update"}',
]);

Using getUpdates method

Using the getUpdates method must not have a webhook parameter set and requires a MySQL database connection:

$bot = new BotManager([
    ...
    // Extras.
    'mysql' => [
        'host'         => '127.0.0.1',
        'port'         => 3306,           // optional
        'user'         => 'root',
        'password'     => 'root',
        'database'     => 'telegram_bot',
        'table_prefix' => 'tbl_prfx_',    // optional
        'encoding'     => 'utf8mb4',      // optional
    ],
]);

Now, the updates can be done either through the browser or via CLI.

Custom getUpdates output

A callback can be defined, to override the default output when updates are handled via getUpdates.

Example of the default output:

...
2017-07-10 14:59:25 - Updates processed: 1
123456: <text>
2017-07-10 14:59:27 - Updates processed: 0
2017-07-10 14:59:30 - Updates processed: 0
2017-07-10 14:59:32 - Updates processed: 0
2017-07-10 14:59:34 - Updates processed: 1
123456: <photo>
2017-07-10 14:59:36 - Updates processed: 0
...

Using custom callback that must return a string:

// In manager.php after $bot has been defined:
$bot->setCustomGetUpdatesCallback(function (ServerResponse $get_updates_response) {
    $results = array_filter((array) $get_updates_response->getResult());

    return sprintf('There are %d update(s)' . PHP_EOL, count($results));
});

output:

...
There are 0 update(s)
There are 0 update(s)
There are 2 update(s)
There are 1 update(s)
...

Development

When running live bot tests on a fork, you must enter the following environment variables to your repository settings on travis-ci.org:

API_KEY="12345:your_api_key"
BOT_USERNAME="username_of_your_bot"

It probably makes sense for you to create a new dummy bot for this.
