Necessary PHP modules when hosting a mirror.

Hello! I am in the process of reinstalling the box that runs our php.net mirror since it has accumulated to much cruft over time. I want to strip it from all unnecessary software and I wonder which, if any, optional PHP modules I have to include to host the pages from www.php.net.
