How can PHP developers prevent unauthorized access to sensitive data in a Content Management System?

To prevent unauthorized access to sensitive data in a Content Management System, PHP developers can implement access control measures such as authentication and authorization. This can be done by requiring users to log in with valid credentials and verifying their permissions before allowing access to sensitive data. 

// Check if user is logged in and has the necessary permissions
session_start();

if (!isset($_SESSION['loggedin']) || $_SESSION['loggedin'] !== true || $_SESSION['role'] !== 'admin') {
    // Redirect user to login page or display an error message
    header('Location: login.php');
    exit;
}

// Access sensitive data here
