I have a 3-column layout on a web page that has a variety of links. After a user clicks on the link, I'd like the content to load in the center column. I know there's a way that PHP can work, but I don't know where to begin.

I appreciate any assistance.

Thank you,

If your going down the route I think you are you want to look into AJAX ... the DOM has the ability to modify certain page contents without reloading the entire page.

This may be a bit advanced to what your trying to accomplish, if so, look into iframes for a simpler option.
