   <?php
   $dsn = 'mysql:host=your_host;dbname=your_dbname';
   $username = 'your_username';
   $password = 'your_password';
   
   try {
       $pdo = new PDO($dsn, $username, $password);
       $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
   } catch (PDOException $e) {
       die('Connection failed: ' . $e->getMessage());
   }
   ?>

3. Configure session settings:

   Ensure the session is properly configured in includes/config_session.inc.php:
