how to implement a websocket server with node.js?
are there any examples? And how 开发者_开发知识库node.js communicates with traditional php scripts ?
Take a look at socket.io. This includes a client and a server-side library.

Well, you should read the (now deprecated) Specification.
For a straight forward implementation you can take a look at my code here:

If you like to have a big wall of abstraction with a trillion fall backs, take a look at: http://socket.io/
BUT...
Keep in mind when building your own one, the WebSocket protocol is about to change due to recently discovered security vulnerabilities:

As for the PHP part, it's unclear to me what you exactly want to do you should give us more information about that.
