I would like to make all my released docs and articles easy to access on an internal website that I want to create. I have important knowledge in web desk but a beginner in coding; so I need a PHP Free template which might include tools like: search tool, latest document checked, related documents, interactive forms to receive feedbacks on my articles. Can you help me or give me the address of a customizable PHP interface that I would tailor? Thanks

sounds like what you need is a wiki.
opensourcecms.com - choose :)

Joomla ?
Drupal?
Mambo?

I would suggest Joomla for informational sites and for you clients and personal sites Instant Update.
