I've begun making a rather large site in html (mostly.) I'm using CSS, so I can update the "look" of the site quite easily among all of the pages.

What I am thinking though, I won't be able to change the links, menus, etc. without changing each page individually. This site will potentially have hundreds of pages so changing each page individually would be awful.

I'm wondering, is there a way to have the parts of my site (such as the left-side column, content, and right-side column) pulled from one source? This way I could edit the one source, and it would subsequently edit all of my pages at once.

If there is a way, could you point me in the right direction?

I think I've narrowed it down to use the <?php include ("filename.php"); ?> code.

Am I on the right track?

Weird... it always seems that whenever I ask for help I finally figure things out. I'd been searching for this for a while, and after posting I found out how.

That code is amazing, by the way.
