A hotel and lodge management system handles online room booking with real-time availability: guests reserve rooms, and staff manage rooms, rates, payments and reports from a back-office dashboard. The booking calendar makes it a great project for learning availability logic.
What it manages
- Rooms, room types and capacity
- Rates by date range, with month-wise advance payment
- Real-time availability and reservations
- Customers, taxes, currencies and invoices
- Reports: bookings, customers and payments
The core challenge: availability without double-booking
The defining problem is making sure two guests can’t book the same room for overlapping dates. You learn to check availability across a date range and lock a room the moment it’s reserved — the same overlapping-interval logic used in every booking system.
Technology stack
A PHP/MySQL web application you can integrate into an existing website, with a back-office reservation manager and invoicing.
What you’ll learn
Date-range availability checks, preventing overlapping bookings, rate management, and booking/payment reporting.
Frequently asked questions
How do I prevent double-booking?
Check for any existing reservation that overlaps the requested dates for that room, and reject or lock at the moment of booking.
Can rates change by season?
Yes — store rates per date range so peak and off-peak pricing is just data.
A note on using this project
Use this PHP/MySQL project as a learning reference: read the code, run it locally, and adapt it to your own requirements rather than deploying it unchanged. If you reuse third-party components, check their licences first.
