How can PHP be used to create a user login system with specific access to different sections of a website?

To create a user login system with specific access to different sections of a website, you can use PHP to authenticate users and manage their permissions. This can be achieved by storing user information in a database, checking credentials during login, and then controlling access to different sections based on the user's role or permissions. 

// Check if user is logged in
session_start();

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

// Check user's role or permissions
$user_id = $_SESSION['user_id'];
// Query database to get user's role or permissions
// Example: $user_role = get_user_role($user_id);

// Check user's role or permissions to access specific sections
if($user_role !== 'admin') {
    header("Location: unauthorized.php");
    exit();
}

// Display content for authorized users
echo "Welcome, Admin!";
