Knowledgebase/FAQ applet for website?

[Matmulder]

I want to implement some kind of Knowledgebase/FAQ section on my website, where people can search a database for ... well, frequently asked questions and get answers to problems, etc.

Wondered if anyone could recommend anything? I don't mind paying as long as its relatively cheap. Needs to be PHP/MySQL compatible.

I'm after something more like this:
