How can PHP beginners effectively manage page access control and prevent unauthorized access to specific pages within their website?

To effectively manage page access control and prevent unauthorized access to specific pages within a website, PHP beginners can implement a simple user authentication system. This can be achieved by creating a login system where users enter their credentials to access restricted pages. By checking the user's authentication status on each restricted page, unauthorized users can be redirected to a login page or denied access altogether. 

session_start();

// Check if the user is logged in
if(!isset($_SESSION['logged_in'])) {
    header('Location: login.php');
    exit();
}

// Restricted page content here
echo "Welcome to the restricted page!";
