## Overview

This repository is CodeIgniter 3, a PHP web-application framework, with an included customer-complaint/questionnaire application. The main runtime path is an HTTP request routed to a controller, which uses framework loading and persistence facilities and returns a view. The README describes the framework’s broader reusable-library role; the tree also identifies app areas for login, registration, questionnaire simulation, administration, and reports. Sampled excerpts support routing, controller setup, query building, and database-backed sessions; unsampled application-controller wiring is not asserted.

Main entry points: [`application/controllers`](https://github.com/prasetyahs/sistemkeluhan/tree/master/application/controllers) (App controllers), [`system/database/DB_query_builder.php`](https://github.com/prasetyahs/sistemkeluhan/blob/master/system/database/DB_query_builder.php) (Query builder), [`index.php`](https://github.com/prasetyahs/sistemkeluhan/blob/master/index.php) (Front controller), [`system/core/CodeIgniter.php`](https://github.com/prasetyahs/sistemkeluhan/blob/master/system/core/CodeIgniter.php) (Framework bootstrap)
