PHP+NodeJS: What websocket frameworks are there for webrpc?

Question

PHP

I got carried away with "pampering" with IoT based on raspberries.
I would like to bring something more or less necessary to life, for this I assembled a piece of iron, deployed a server on the Internet and I want to fasten the web interface.
I want to interact in real time so that IoT has the ability to break through firewalls using regular means (Websocket), I plan to deploy the server in PHP.
Native socket.io + phpsocket is good for everyone, except that it implements the pub / sub concept, and I need rpc (request - response) + pubsub Tell me
if anyone has experience with libraries that would support both protocols + clients on NodeJS +PHP ?
Thanks
