## Overview

BlueBird is a PHP hotel-booking site with a staff-facing management panel. Guests authenticate and submit room/date requests; staff review and confirm bookings, which creates payment records for payment management and invoicing. The panel also covers room and staff administration, exports, and dashboard reporting. The sampled pages show direct MySQL access through a shared connection rather than a separate service layer. Several admin capabilities are documented or present in the tree but not sampled, so their internal data flows are left unasserted.

Main entry points: [`config.php`](https://github.com/tushar-2223/hotel-management-system/blob/main/config.php) (MySQL connection), [`admin/admin.php`](https://github.com/tushar-2223/hotel-management-system/blob/main/admin/admin.php) (Admin panel), [`admin/roombook.php`](https://github.com/tushar-2223/hotel-management-system/blob/main/admin/roombook.php) (Booking review), [`admin/payment.php`](https://github.com/tushar-2223/hotel-management-system/blob/main/admin/payment.php) (Payment records)
