How can sessions and cookies be effectively combined for user management in a PHP community system?

Sessions can be used to store user data during a user's visit to a website, while cookies can be used to persist user data across visits. In a PHP community system, sessions can be used to store temporary user data such as login status, while cookies can be used to remember user preferences or login credentials. By combining sessions and cookies effectively, you can create a seamless user management experience for your community system.

// Start a session
session_start();

// Set a session variable for user login status
$_SESSION['logged_in'] = true;

// Set a cookie to remember user preferences
setcookie('user_preferences', 'value', time() + (86400 * 30), '/');

// Set a cookie to remember user login credentials
setcookie('username', 'example_user', time() + (86400 * 30), '/');
setcookie('password', 'example_password', time() + (86400 * 30), '/');
