Android中的Web Socket来自PHP Server

I have developed PHP server + Google CLoud Messaging to push Message to Android Clients.

1. Client send message to Server using HTTPConnection
2. Server send message to clients using Google Cloud Messaging

But I want to know if I can make my own Push Messaging using websocket?

I have tried using XAMPP as my PHP Server.

And using html5 websocket as clients.

But I never tried using android as my clients.

Does anyone know how to do something like that?

What I want is full communication.

For example:

client a -> send "Hello World" to server

client a, b, c, d, e, etc. will get the "Hello World" from server without having the needs of client b, c, d, e doing something.

Thanks in advance, if this question is asked before, I'm really sorry.
