Persistant Socket Across Different Scripts

I am trying to figure out if there is a way to have a socket persist in different executions of the same script. My situation is as follows; I have a Java program running and waiting for connections on port 10000. When it receives a connection it reads a "device" id and loads a device driver for it and then passes the stream to this driver. I would like to be able to communicate over this stream with the client using a browser and PHP. I can open the stream when the script runs for the first time, but each time the user gets the script again the connection is being re-made. I tried pfsockopen but it seemed to work the same of fsockopen. Thanks very much, Justin
