PHP + nodejs + socket: Is there any instance for real-time communication?

PHP + nodejs + socket is there any instance for real-time communication? The js server built with nodejs can implement real-time communication similar to websocket for persistent connections and unrestricted connections. I recently watched nodejs and installed the zeromq module of nodejs in Linux. the examples module is js running on the server, how can I implement real-time communication in client h PHP + nodejs + socket? is there an instance?
The js server built with nodejs can implement real-time communication similar to websocket for persistent connections and unrestricted connections.
I recently watched nodejs and installed the Node. js zeromq module in Linux. the examples module is js running on the server. I have never known how to use the socket function in the client html. The websocket module's html example can also be found, but none of the zeromq client subscription examples are available. js usage in html is different from that in websocket module, has Daniel engaged in such real-time communication, message push, and customer subscription projects ???
The number of new messages displayed after a user logs on to csdn seems to be!
------ Solution --------------------
JavaScript and html4 cannot be socket-only through http, client requests, or persistent connections


Html5 has websocket.
