How can the PHP session handling be optimized to ensure secure user authentication and data management?

To optimize PHP session handling for secure user authentication and data management, it is important to use secure session configuration settings, such as setting the session cookie parameters to secure and HTTP only, using HTTPS for all communication, regenerating the session ID after successful user authentication, and properly validating and sanitizing user input before storing it in the session. 

// Set secure session configuration settings
ini_set('session.cookie_secure', 1);
ini_set('session.cookie_httponly', 1);

// Start secure session
session_start();

// Regenerate session ID after successful user authentication
if(isset($_SESSION['authenticated']) && $_SESSION['authenticated'] === true){
    session_regenerate_id(true);
}

// Validate and sanitize user input before storing in session
$_SESSION['username'] = filter_var($_POST['username'], FILTER_SANITIZE_STRING);
