How can user permissions be managed efficiently in a PHP-based CMS to ensure real-time updates?

To manage user permissions efficiently in a PHP-based CMS for real-time updates, you can use a combination of role-based access control (RBAC) and session management. RBAC allows you to assign specific roles to users with corresponding permissions, while session management ensures that user permissions are checked in real-time during each request. 

// Check user permissions in real-time using RBAC and session management

// Define user roles and corresponding permissions
$roles = [
    'admin' => ['update_content', 'delete_content'],
    'editor' => ['update_content'],
    'viewer' => []
];

// Check user role from session data
$user_role = $_SESSION['user_role'];

// Check if user has permission for a specific action
function check_permission($action, $user_role) {
    global $roles;
    
    if (in_array($action, $roles[$user_role])) {
        return true;
    } else {
        return false;
    }
}

// Example usage
if (check_permission('update_content', $user_role)) {
    // Allow user to update content
    echo "User has permission to update content.";
} else {
    // Deny access
    echo "User does not have permission to update content.";
}
