I am very much a Linux newbie. I am running a server with Centos release 5.5 which has PHP Version 5.1.6 installed on it with '--disable-dom' set at compile time. I want to change this and from what I have read I can achieve this by installing php-xml.
Looking at various pages on the web I am sea how I go about doing this from the command line. Could someone help me through the steps?
