Activity 12: Members Only Session Management

This activity demonstrates a functional login and logout system using PHP sessions. A session allows the website to remember if a user is logged in.

Try opening the Members Only page. If you are not logged in, the website will redirect you to the login page.

Session Protection Source Code

session_start();

if (!isset($_SESSION["user_id"])) {
    header("Location: login.php");
    exit;
}

echo "Welcome to the Members Only page.";
