## Overview

CodeIgniter is a PHP web application framework; this repository also includes an application scaffold with authentication, user, admin, and menu areas. The main workflow is an HTTP request routed to a controller, which loads models or libraries and renders a view. The tree and excerpts support the framework’s routing, controller, query-builder, and database-session roles, while many other library capabilities are evident from filenames rather than sampled implementation. The graph keeps those capabilities visible without asserting their internal wiring.

Main entry points: [`system/core/Router.php`](https://github.com/agusdhermawan/sso/blob/main/system/core/Router.php) (URI router), [`application/controllers/Auth.php`](https://github.com/agusdhermawan/sso/blob/main/application/controllers/Auth.php) (Authentication), [`system/core/Controller.php`](https://github.com/agusdhermawan/sso/blob/main/system/core/Controller.php) (Controller base), [`application/controllers/Menu.php`](https://github.com/agusdhermawan/sso/blob/main/application/controllers/Menu.php) (Menu management)
