What are the best practices for securing pages after the domain using PHP?

Securing pages after the domain using PHP involves implementing proper authentication and authorization mechanisms to control access to these pages. This can be achieved by using session management, user roles, and permissions to restrict unauthorized users from accessing sensitive content. 

session_start();

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

// Check user role or permissions to access the page
if($_SESSION['role'] != 'admin') {
    header("Location: unauthorized.php");
    exit();
}

// Your secure page content here
