kazitoha/event-management-system ? reverse-engineered prompt

Build me a simple event management web app where an admin can log in and create, edit, and delete events, and also keep track of people who register for them. I want a clean interface for managing event details, seeing attendee lists, and searching through both events and attendees. Please include an easy registration flow that feels fast on the page, and make sure the app can also return event data as JSON so it can be used from other tools or pages later.

Use a straightforward PHP and MySQL setup that runs on a normal local server like XAMPP, and make it easy to configure the database connection. If you need to look up current docs online while building, go ahead. Please also include the basic admin access and make sure the whole thing is ready to import the database and run without a lot of extra setup.
