What are some best practices for preventing unauthorized access to your data in PHP?

To prevent unauthorized access to your data in PHP, it is crucial to implement proper authentication and authorization mechanisms. This includes using secure login systems, validating user input, and restricting access to sensitive data based on user roles and permissions. 

// Example of restricting access to sensitive data based on user roles
session_start();

if ($_SESSION['user_role'] !== 'admin') {
    // Redirect to a different page or display an error message
    header('Location: unauthorized.php');
    exit;
}

// Display sensitive data only to users with 'admin' role
echo "Welcome, Admin! Here is the sensitive data.";
