How can beginner PHP developers ensure they are using up-to-date and secure methods for session management in their code?

To ensure they are using up-to-date and secure methods for session management in their code, beginner PHP developers should utilize PHP's built-in session handling functions, such as session_start() and session_regenerate_id(). They should also set session cookie parameters securely, use HTTPS to encrypt session data in transit, and validate and sanitize all user input to prevent session hijacking and other security vulnerabilities. 

// Start a secure session
session_start();

// Set session cookie parameters
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true,
    'samesite' => 'Strict'
]);

// Regenerate session ID to prevent session fixation attacks
session_regenerate_id(true);

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