Hello ReactPHP community,

I would like to share a small experiment that combines ReactPHP with a custom nghttp2 PHP extension to build a minimal HTTP/2 client and server.

Repository:
https://github.com/masakielastic/reactphp-nghttp2-examples

The goal of this repository is to explore how HTTP/2 support could be integrated with ReactPHP's event loop while keeping the implementation relatively simple.

The examples include:

• A minimal HTTP/2 client
• A minimal HTTP/2 server
• Integration with the ReactPHP event loop
• Use of nghttp2 for the HTTP/2 protocol layer

The nghttp2 extension exposes HTTP/2 session and stream events to PHP, while ReactPHP handles the asynchronous I/O and connection lifecycle.

This experiment is not intended to be a production-ready solution.
Instead, the purpose is to explore architectural ideas such as:

• how HTTP/2 sessions could fit into the ReactPHP ecosystem
• how protocol-level events (streams, headers, data frames, etc.) might map to userland APIs
• how a native HTTP/2 implementation could coexist with existing ReactPHP components

If you are interested in HTTP/2 support for ReactPHP or building custom protocol libraries on top of the event loop, I hope these examples might be useful as a reference.

Feedback and suggestions are very welcome.
