Build me a simple student app in PHP for managing student records.

I want something clean and easy to use where I can add, view, edit, and remove students, and see their basic details in one place. Keep the interface straightforward and make it feel like a small school admin tool. If it helps, use current best practices and look up any docs online if you need to.

Please make it work end to end, with a polished page for the app, basic form validation, and a layout that looks decent on desktop and mobile.
