categories

I am trying to find some example code or best practices about making CMS-type categories with PHP.

This is a problem that has for sure been solved gazillion times but for some reason I am unable to find any example code using PHP about how to implement this.

As far as I can tell, there are two parts to the problem. The first one has to with the styling side of things:

outputting the link in the navigation so that the current page has a special style (class="active") and
to not print out the link for the current page.

The second part is handling categories, subcategories and the dynamic pages under the categories.

The second part seems pretty straightforward. I am thinking of making it so that the name of the category in the navigation is a link to categories.php?id=x and on this page I just print out the pages with that category id. Then, if the user klicks on a page he will be taken to pages.php?id=y.

However, I am not quite sure on how to make a navigation to check if we are now on the current page. Should I just use some case switch or what?

Any ideas or links to some good example code are much appreciated.
