Webhook installation

You need server with https and composer support. You must set a WebHook Create set.php (just edit example-set.php) and put into it:

<?php
//Composer Loader
$loader = require __DIR__.'/vendor/autoload.php';

$API_KEY = 'your_bot_api_key';
$BOT_NAME = 'namebot';
$link = 'https://yourdomain/yourpath_to_hook.php';
try {
    // create Telegram API object
    $telegram = new Longman\TelegramBot\Telegram($API_KEY, $BOT_NAME);
    // set webhook
    $result = $telegram->setWebHook($link);
    if ($result->isOk()) {
        echo $result->getDescription();
    }
} catch (Longman\TelegramBot\Exception\TelegramException $e) {
    echo $e;
}

And open your set.php via browser.

After create hook.php (just edit example-hook.php) and put:

<?php
$loader = require __DIR__.'/vendor/autoload.php';

$API_KEY = 'your_bot_api_key';
$BOT_NAME = 'namebot';

try {
    // create Telegram API object
    $telegram = new Longman\TelegramBot\Telegram($API_KEY, $BOT_NAME);

    // handle telegram webhook request
    $telegram->handle();
} catch (Longman\TelegramBot\Exception\TelegramException $e) {
    // log telegram errors
    // echo $e;
}

getUpdate installation NEW!

You need the database Mysql active.

Create getUpdateCLI.php (just edit example-getUpdateCLI.php) and put into it:

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

$API_KEY = 'your_bot_api_key';
$BOT_NAME = 'namebot';
$credentials = array('host'=>'localhost', 'user'=>'dbuser', 'password'=>'dbpass', 'database'=>'dbname');

try {
    // create Telegram API object
    $telegram = new Longman\TelegramBot\Telegram($API_KEY, $BOT_NAME);
    $telegram->enableMySQL($credentials);
    // handle telegram getUpdate request
    $telegram->handleGetUpdates();
} catch (Longman\TelegramBot\Exception\TelegramException $e) {
    // log telegram errors
     echo $e;
}                

give to the file the permission for execution:

chmod 775 getUpdateCLI.php

then run

./getUpdateCLI.php

Utilis

MySQL storage (Recomended)

If you want insert in database messages/users/chats for further usage in commands, create database and import structure.sql and enable Mysql support after object creation and BEFORE handle method:

$credentials = array('host'=>'localhost', 'user'=>'dbuser',
'password'=>'dbpass', 'database'=>'dbname');

$telegram->enableMySQL($credentials);

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

$telegram->enableMySQL($credentials, $BOT_NAME.'_');

Commands

The bot is able to recognise commands in chat with multiple bot( /command@mybot ). It can execute command triggering a chat event. Here's the list:

• Group chat created (GroupchatcreatedCommand.php)
• New chat participant (NewchatparticipantCommand.php)
• Delete chat photo (DeletechatphotoCommand.php)
• New chat title (NewchattitleCommand.php)
• Left chat participant (LeftchatparticipantCommand.php)

GenericCommand.php lets you handle commands that don't exist or to use commands as a variable: Favourite colour? /black, /red Favourite number? /1, /134

Maybe you would like to develop your own commands. A good practice is to store them outside vendor/. This can be done adding the method:

$COMMANDS_FOLDER = __DIR__.'/Commands/';
$telegram->addCommandsPath($COMMANDS_FOLDER);

Admin Commands (new!)

Enabling this feature, the admin bot can perform some super user command like send message to all. You can specify one or more admin with this option:

$telegram->enableAdmins(array('TelegramUserID','Othersid'));

Telegram user id can be retrieved with the command /whoami. Admin commands are stored in src/Admin/ folder. To know all the commands avaiable type /help.

Commands Configuration

With this method you can set some command specified parameters, for example, google geocode/timezone api key for date command:

$telegram->setCommandConfig('date',
array('google_api_key'=>'your_google_api_key_here'));

Send message to all active chats

To do this you have to enable the Mysql connection. Here's an example of use:

$results = $telegram->sendToActiveChats(
        'sendMessage', //callback function to execute (see Request.php methods)
        array('text'=>'Hey! Checkout the new feature!!'), //Param to
evaluate the request
        true, //Send to chats (group chat)
        true, //Send to users (single chat)
        null, //'yyyy-mm-dd hh:mm:ss' date range from
        null  //'yyyy-mm-dd hh:mm:ss' date range to
    );

print_r($results);

Logging

You can also log incoming messages on a text file, set this option with the methods:

$telegram->setLogRequests(true);
$telegram->setLogPath($BOT_NAME.'.log');

Thrown Exception are stored in TelegramException.log file.
