php/frankenphp ? reverse-engineered prompt

Build me a modern PHP app server called FrankenPHP that I can run locally and in production.

I want it to serve PHP apps straight from the current folder, run PHP scripts from the command line, and support a faster worker mode for frameworks like Laravel and Symfony. It should feel like a proper web server, with HTTPS built in, HTTP 2 and HTTP 3 support, hot reloading, good logging, and support for real time features like Mercure. Please make sure it can also be used as a Go library so other Go apps can embed PHP through net/http.

I’d like the project to be usable on Linux, macOS, and Windows, with install scripts, Docker support, and a clean way to configure things like the server name and PHP options. If anything needs up to date docs or current best practices, look them up online. Also include tests and example usage so it’s easy to verify the main server modes work.
