A doctor appointment system lets patients book consultations online and gives clinic staff a clear schedule to manage. It removes phone-tag and double-bookings, and it’s a focused project that teaches scheduling logic without overwhelming scope.
What patients can do
- Create a free account
- Browse doctors and their available slots
- Book, view and manage appointments
What the admin can do
- Add doctors and their schedules
- Define time slots and availability
- Monitor daily transactions and patient records
The scheduling problem
The key challenge is preventing two patients from grabbing the same slot. You learn to model availability as discrete slots, lock a slot the moment it’s booked, and validate on the server so a race between two requests can’t create a double-booking.
Technology stack
Built with PHP (often CodeIgniter), MySQL, HTML and JavaScript. A clean, responsive layout makes it comfortable on mobile, where most patients will book.
Setup overview
- Extract the source into your web root.
- Create a database and import the provided SQL file.
- Open the app in a browser and sign in as admin to add doctors and slots.
What you’ll learn
Slot-based scheduling, conflict prevention, role separation between patients and staff, and dashboard reporting of daily activity.
Frequently asked questions
How do I stop double-booking?
Treat each slot as a unique, lockable record and validate availability server-side at the moment of booking, not just in the UI.
Can it support several doctors?
Yes — it is designed as a multi-doctor system; each doctor has independent schedules and slots.
A note on using this project
This guide is written to help students and developers understand how a PHP/CodeIgniter application like this is designed and built. Treat any sample code as a learning reference: read it, run it locally, and adapt it to your own requirements rather than shipping it unchanged. If you reuse third-party components, check their licences first.
