TelegramBotPHP

A very simple PHP Telegram Bot API for sending messages.
(Almost) Compliant with the May 18, 2017 Telegram Bot API update.

Requirements

PHP5
Curl for PHP5 must be enabled.
Telegram API key, you can get one simply with @BotFather with simple commands right after creating your bot.

For the WebHook:

An SSL certificate (Telegram API requires this). You can use Cloudflare’s Free Flexible SSL which crypts the web traffic from end user to their proxies if you’re using CloudFlare DNS.
Since the August 29 update you can use a self-signed ssl certificate.

For the GetUpdates:

Some way to execute the script in order to serve messages (for example cronjob)

Installation

Copy Telegram.php into your server and include it in your new bot script
```
include("Telegram.php");
$telegram = new Telegram($bot_id);
```
To enable error log file, also copy TelegramErrorLogger.php in the same directory of Telegram.php file

Using Composer

From your project directory, run

composer require eleirbag89/telegrambotphp

Configuration (WebHook)

Navigate to https://api.telegram.org/bot(BOT_ID)/setWebhook?url=https://yoursite.com/your_update.php Or use the Telegram class setWebhook method.

Examples

$telegram = new Telegram($bot_id);
$chat_id = $telegram->ChatID();
$content = array('chat_id' => $chat_id, 'text' => "Test");
$telegram->sendMessage($content);

If you want to get some specific parameter from the Telegram response:

$telegram = new Telegram($bot_id);
$result = $telegram->getData();
$text = $result["message"] ["text"];
$chat_id = $result["message"] ["chat"]["id"];
$content = array('chat_id' => $chat_id, 'text' => "Test");
$telegram->sendMessage($content);

To upload a Photo or some other files, you need to load it with CurlFile:

// Load a local file to upload. If is already on Telegram's Servers just pass the resource id
$img = curl_file_create('test.png','image/png'); 
$content = array('chat_id' => $chat_id, 'photo' => $img );
$telegram->sendPhoto($content);

To download a file on the Telegram’s servers

$file = $telegram->getFile($file_id);
$telegram->downloadFile($file["result"]["file_path"], "./my_downloaded_file_on_local_server.png");

See update.php or update cowsay.php for the complete example. If you wanna see the CowSay Bot in action add it.

If you want to use GetUpdates instead of the WebHook you need to call the the serveUpdate function inside a for cycle.

$req = $telegram->getUpdates();
for ($i = 0; $i < $telegram-> UpdateCount(); $i++) {
	// You NEED to call serveUpdate before accessing the values of message in Telegram Class
	$telegram->serveUpdate($i);
	$text = $telegram->Text();
	$chat_id = $telegram->ChatID();

	if ($text == "/start") {
		$reply = "Working";
		$content = array('chat_id' => $chat_id, 'text' => $reply);
		$telegram->sendMessage($content);
	}
	// DO OTHER STUFF
}

See getUpdates.php for the complete example.

Build keyboards

Telegram’s bots can have two different kind of keyboards: Inline and Reply.
The InlineKeyboard is linked to a particular message, while the ReplyKeyboard is linked to the whole chat.
They are both an array of array of buttons, which rapresent the rows and columns.
For instance you can arrange a ReplyKeyboard like this: ReplyKeabordExample using this code:

$option = array( 
    //First row
    array($telegram->buildKeyboardButton("Button 1"), $telegram->buildKeyboardButton("Button 2")), 
    //Second row 
    array($telegram->buildKeyboardButton("Button 3"), $telegram->buildKeyboardButton("Button 4"), $telegram->buildKeyboardButton("Button 5")), 
    //Third row
    array($telegram->buildKeyboardButton("Button 6")) );
$keyb = $telegram->buildKeyBoard($option, $onetime=false);
$content = array('chat_id' => $chat_id, 'reply_markup' => $keyb, 'text' => "This is a Keyboard Test");
$telegram->sendMessage($content);

When a user click on the button, the button text is send back to the bot.
For an InlineKeyboard it’s pretty much the same (but you need to provide a valid URL or a Callback data) InlineKeabordExample

$option = array( 
    //First row
    array($telegram->buildInlineKeyBoardButton("Button 1", $url="http://link1.com"), $telegram->buildInlineKeyBoardButton("Button 2", $url="http://link2.com")), 
    //Second row 
    array($telegram->buildInlineKeyBoardButton("Button 3", $url="http://link3.com"), $telegram->buildInlineKeyBoardButton("Button 4", $url="http://link4.com"), $telegram->buildInlineKeyBoardButton("Button 5", $url="http://link5.com")), 
    //Third row
    array($telegram->buildInlineKeyBoardButton("Button 6", $url="http://link6.com")) );
$keyb = $telegram->buildInlineKeyBoard($option);
$content = array('chat_id' => $chat_id, 'reply_markup' => $keyb, 'text' => "This is a Keyboard Test");
$telegram->sendMessage($content);
