What strategies can be employed to easily expand and enhance a PHP script for admin interfaces and user rights management?

To easily expand and enhance a PHP script for admin interfaces and user rights management, one strategy is to implement a role-based access control system. This involves creating different user roles (such as admin, editor, user) and assigning specific permissions to each role. By checking the user's role and permissions before allowing access to certain admin interfaces or actions, you can ensure that only authorized users can perform specific tasks. 

// Example code for role-based access control in PHP

// Define user roles and their permissions
$roles = [
    'admin' => ['manage_users', 'manage_content'],
    'editor' => ['manage_content'],
    'user' => []
];

// Check user role and permissions before allowing access
function hasPermission($user_role, $permission_needed) {
    global $roles;
    
    if(isset($roles[$user_role]) && in_array($permission_needed, $roles[$user_role])) {
        return true;
    } else {
        return false;
    }
}

// Example usage
$user_role = 'admin';
$permission_needed = 'manage_users';

if(hasPermission($user_role, $permission_needed)) {
    // Allow access to manage users interface
    echo "Access granted!";
} else {
    // Display error message or redirect to unauthorized page
    echo "Access denied!";
}
