ramazantufekci/not ? reverse-engineered prompt

Build me a simple note taking web app in PHP that lets me add, view, edit, and delete notes from a clean page. I want it to feel easy to use, with a straightforward form to create a note and a list of saved notes I can open later.

Please keep it simple and practical, with the app working out of the box and a basic visual layout using the existing templates. If you need to make choices about how notes are stored, pick the simplest reliable option and keep the code easy to understand. Also add a few tests so the main note actions are covered, and make sure the project is ready to run without extra hassle. If something depends on current best practices or recent PHP details, look up the latest docs online if needed.
