## Overview

This is a CodeIgniter-based hospital management application. Its main user-to-result workflows are patients browsing doctors and requesting appointments, and clinical staff managing patient records and prescriptions; administrators oversee hospital entities and financial activity. The README documents these capabilities, but sampled application source is limited, so feature relationships are cited to the README rather than inferred controller-to-model calls. The framework bootstrap, loader, and session layer are shown as supporting runtime components; vendor libraries are omitted.

Main entry points: [`application/models`](https://github.com/coder-rukon/hospital-management-system-php-project/tree/master/application/models) (Domain Models), [`system/core/CodeIgniter.php`](https://github.com/coder-rukon/hospital-management-system-php-project/blob/master/system/core/CodeIgniter.php) (Framework Bootstrap), [`application/controllers/Patient.php`](https://github.com/coder-rukon/hospital-management-system-php-project/blob/master/application/controllers/Patient.php) (Patient Accounts), [`application/controllers/Doctors.php`](https://github.com/coder-rukon/hospital-management-system-php-project/blob/master/application/controllers/Doctors.php) (Doctor Records)
