Installation

Via Composer's autoloader

After downloading by using Composer, you can include Composer's autoloader:

php
include (__DIR__ . '/vendor/autoload.php');

$telegram = new Telegram('YOUR TELEGRAM TOKEN HERE');

Via TelegramBotPHP class

Copy Telegram.php into your server and include it in your new bot script:

php
include 'Telegram.php';

$telegram = new Telegram('YOUR TELEGRAM TOKEN HERE');

Note: To enable error log file, also copy TelegramErrorLogger.php in the same directory of Telegram.php file.

Configuration (WebHook)

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

Examples

php
$telegram = new Telegram('YOUR TELEGRAM TOKEN HERE');

$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:

php
$telegram = new Telegram('YOUR TELEGRAM TOKEN HERE');

$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:

php
// 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

php
$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.

php
$telegram = new Telegram('YOUR TELEGRAM TOKEN HERE');

$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:

php
$option = array( 
    //First row
    array($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

php
$option = array( 
    //First row
    array($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);
