Qloapps/QloApps ? reverse-engineered prompt

I want to build a complete hotel reservation system, something like QloApps. It should be a full, self-hosted website that I can run for my own hotel business.

The main thing is having a public-facing website where guests can browse available rooms, check dates, see prices, and make a booking directly. It needs to look clean and professional to attract customers.

Then, I need a secure admin backend or property management system (PMS) where I can manage everything. In this admin area, I should be able to define different room types, manage my inventory of rooms, set pricing, and see and manage all the guest reservations that come in.

Please build this using PHP and a MySQL database. It should be a complete application with a clear installation process so I can deploy it on a standard web server like Apache.
