I uploaded a simple starting level project created using PHP and MySQL (link
https://phpfromexample.blogspot.com/). This is a "Installment Payment System" for an electronic store, but you can use it for any other similar business. This "Acme Electronics" is an electronic item retailer who sells items to its customers on easy payment schemes. Customers can buy electronic products from this retailer and pay by monthly installments.
So our client want to have a system that can record customer details, sales records, and payment details. Customer want to track each customer's sales and details of installment payments and how many monthly premiums to pay.
The system was created using PHP and MySQL so the customer can host the system in an online web server and access to the system from any where any time.
This posted system developed only for educational purpose and there are so many further developments needed it to run in a real environment. This is to learn programming using PHP and MySQL and after studying the code and database you will gain good knowledge in how to develop a system for your final project.
It is not advisable to use the posted system as it is for any kind of academic project. You can gain ideas and learn from source code and develop your own system to submit for the project.
NOTE:
Acme Electronics is a fictional organization and this system does not developed based on any real requirement. This is a fictional project for students to learn about programming using PHP and MySQL.
