TeleBot

A minimal library to develop your new Telegram bot

Installation

composer require webpajooh/telebot

How to use

Start point

We start by creating an instance of TeleBot class:

try {
    $tg = new TeleBot('YOUR_BOT_TOKEN');
} catch (Throwable $th) {...}

Get the update object

There are short ways to access the update object and some important fields. I recommend you to read the official documentation to understand these objects well.

$tg->update
$tg->message
$tg->chat
$tg->user

You also can use the hasCallbackQuery() method, when you want to check if the update object has a callback_query field.

Methods

Thanks to magic methods, we can use API methods without implementing them, and just call them by name and pass an array as parameter:

$tg->editMessageText([...])

Router

You may define some routes to your bot features; define them by the listen() method:

$tg->listen('/start', function () use ($tg) {
    $tg->sendMessage([
        'chat_id' => $tg->user->id,
	'text' => 'Hello, world!',
    ]);
}, false);

The third parameter that is true by default, makes you able to terminate the script after running a command. In the previous example we passed false so script continues.

You can also get parameters and use them as variables:

$tg->listen('set_age_%d', function ($age) use ($tg) {
    // TODO
});

TeleBot translates them to regex, so it will be good to take a look at this table to know how to use them properly:

Type	TeleBot	Regex
Digits	%d	(\d+)
String (Anything but a whitespace)	%s	(\S+)
Character	%c	(\S)
Everything including an empty string	%p	(.*)

Logger

You may need to log something into a log.txt file:

Logger::log($tg->user->id);
tl($tg->user->id); // Does the same thing

Keyboard

TeleBot includes two classes for making keyboards; InlineKeyboard and ReplyKeyboard. Here you see an example:

$keyboard = (new InlineKeyboard())
    ->addCallbackButton('📕 Help', 'help_callback')
    ->addUrlButton('📱 Share', 'https://t.me/share/url?url=https://t.me/your_awesome_bot&text=Some text')
    ->chunk(1)
    ->rightToLeft()
    ->get();

Then you can use it as bellow:

$tg->sendMessage([
    // Other parameters
    'reply_markup' => $keyboard,
]);

Consider that the chunk() method supports more complex orders, just pass an array like [1, 3, 2] to build such a keyboard:

[        1        ]  
[ 2 ]  [ 3️ ]  [ 4 ]  
[   5   ] [   6   ]  

Default parameters

Sometimes you do not want to repeat yourself by passing a parameter everywhere, so you can define default parameters for each method. Here are three example that makes it clear how to use it:

$tg->setDefaults('sendMessage', ['parse_mode' => 'html']); // You will not need passing parse_mode anymore
$tg->setDefaults(['sendMessage', 'banChatMember'], ['chat_id' => $chatId]);
$tg->setDefaults('*', ['chat_id' => $chatId]); // a default parameter for all methods

Extend it!

You may want to add some methods to TeleBot class to improve your code readability and avoid duplication. Look at this simple example as an inspiration:

TeleBot::extend('isReply', function () {
    return property_exists($this->message, 'reply_to_message');
});

if ($tg->isReply()) { ... }
