## Overview

This PHP food-ordering application lets customers register or log in, browse food, add items to a session cart, apply vouchers, and proceed to payment; admins can log in and manage food and vouchers. The graph separates customer flows, administration, and shared persistence. Source excerpts confirm the main database operations; several view-to-controller links are supported by the source index. The payment implementation and some unsampled views are only represented at the level supported by their paths and references.

Main entry points: [`Food_Ordering_System/User/DB/db.php`](https://github.com/mdtanvirhasib/online-food-ordering-platform/blob/main/Food_Ordering_System/User/DB/db.php) (User DB connection), [`Food_Ordering_System/User/control/userreg.php`](https://github.com/mdtanvirhasib/online-food-ordering-platform/blob/main/Food_Ordering_System/User/control/userreg.php) (Registration), [`Food_Ordering_System/Admin/DB/db.php`](https://github.com/mdtanvirhasib/online-food-ordering-platform/blob/main/Food_Ordering_System/Admin/DB/db.php) (Admin DB connection), [`Food_Ordering_System/User/View/cart.php`](https://github.com/mdtanvirhasib/online-food-ordering-platform/blob/main/Food_Ordering_System/User/View/cart.php) (Cart view)
