Hello,

I experimented with implementing a minimal HTTP/2 client using the
low-level react/socket component and wanted to ask whether something
like this could be useful as an educational example.

The goal of this example is to demonstrate how HTTP/2 frames can be
exchanged over a TLS connection using ReactPHP's socket abstraction.

The implementation intentionally avoids external HTTP/2 libraries so
that the protocol behavior can be observed at the frame level.

This example is intentionally minimal and intended for educational
purposes only. It is not a complete HTTP/2 implementation and is not
intended for production use.

The example demonstrates:

• HTTP/2 client connection preface
• SETTINGS / SETTINGS ACK exchange
• minimal HEADERS request
• simple frame parsing
• reading DATA frames

Full example and explanation:

Would something like this be appropriate as an example for
reactphp/socket, or would it be better kept as an external example?

If this looks useful, I would be happy to open a pull request.

Any feedback would be appreciated.
