file uploading from browser

Hi, I'm having trouble with a file upload php script. I can upload a file, but when I try to transfer it from the temporary location to anywhere within my domain, permission is denied. I had exactly the same problem with the same script on another server and tech support fixed it with the following explanation: "What is happening is that the user php runs as ends up as the file owner - and you are not having permission to do anything to these files. To resolve the problem I have added you to the php group." What I need to know is - how I do this on my new server? As before the server is linux/apache. I have full telnet access, but I have no idea how to add myself to the php group. Regards, Robert MacCombe
