Build me a simple online shopping website in PHP with a clean customer side and an admin side.

Customers should be able to browse products, search and filter them, open a product page, add items to a cart, go through checkout, register, log in, and see a successful payment or order confirmation page. The site should feel like a basic e commerce store and work well on a local server with a MySQL database.

The admin area should let me add and manage products, manage users, and handle the store content from a dashboard. I want the pages to be connected properly, with shared header and footer layout, and the basic login and logout flow working end to end.

Please also include the database setup and make it easy to run locally with XAMPP. If you need to check current docs or best practices while building it, go ahead and look them up online.
