I am new to making WebSockets applications, and I am trying to set up Ratchet (as server-side will be completely in PHP).
Everything was working correctly, until I got to "Push notifications" part. There is written, that you can use plain sockets for push notifications, but they prefer using ZeroMQ. Can you please show me an example / point me to some tutorial, how to use that plain sockets? (I don't want to use ZeroMQ because of limited access to production server, almost without possibility to install stuff there)
Or if there is a library for it, which doesn't require installation of some extensions stuff, can you send me to their docs?
Thanks for any help.
