Cancel all active sessions

If you want to cancel all active session by a timer or cronjob you can do just like this example:

<?php
// Load composer
require __DIR__ . '/vendor/autoload.php';
require_once 'db.php';
require_once 'class.DBPDO.php';

use Longman\TelegramBot\Request;
use Longman\TelegramBot\Telegram;
use Carbon\Carbon;
$API_KEY = 'xxxx';
$BOT_NAME = 'xxxx';
$telegram = new Telegram($API_KEY, $BOT_NAME);

$message = "Your session expired please touch /start to start again";
$update = [':status' => "active"];
$pdo = new DBPDO();


$res = $pdo->fetchAll("SELECT * FROM `conversation` WHERE `status` = 'active' AND `updated_at` < '".Carbon::parse('-15 minute')->toDateTimeString()."' ", $update);
foreach ($res as $user) {
  $chat_id = $user["chat_id"];
  $sql="UPDATE `conversation` SET `status` = 'stopped' WHERE `conversation`.`id` =".$user["id"];
  $pdo->execute($sql);
  if ($chat_id !== '' && $message !== '') {
      $data = [
          'chat_id' => $chat_id,
          'text'    => $message,
      ];
    $result = Request::sendMessage($data);
      if ($result->isOk()) {
          echo 'Message sent succesfully to: ' . $chat_id . "\n";
      } else {
          echo 'Sorry message not sent to: ' . $chat_id . "\n";
      }
  }
}
