## Overview

CodeIgniter is a PHP web-application framework: an incoming request is bootstrapped, routed to a controller, processed through framework services and application code, then rendered or returned as a response. The repository also contains an application with authentication, administration, district/tehsil and hospital pages, and REST endpoints. The README describes the framework’s libraries and structure; sampled source confirms controller/loader behavior, query building, database-backed sessions, and REST request handling. Several application subsystems are represented by their tree paths because their source was not sampled.

Main entry points: [`application/controllers`](https://github.com/codeforpakistan/mostahiq-adminpanel/tree/main/application/controllers) (App controllers), [`application/core/MY_Controller.php`](https://github.com/codeforpakistan/mostahiq-adminpanel/blob/main/application/core/MY_Controller.php) (App base controller), [`application/libraries/REST_Controller.php`](https://github.com/codeforpakistan/mostahiq-adminpanel/blob/main/application/libraries/REST_Controller.php) (REST endpoints), [`system/core/Output.php`](https://github.com/codeforpakistan/mostahiq-adminpanel/blob/main/system/core/Output.php) (Response output)
