The "require()" and "include()" variables both bring in a called, parsed page into the calling page the functions are in. The only difference between the two is how they handle errors. Advantages would include better organization. Using these functions, it is very easy to organize a website - by being able to edit one page, and dynamicly edit many other pages at the same time. The functions are quick and easy, assuming the server isn't very busy and can handle well-sized loads. Disadvantages would include how these functions are bandwidth eaters - parsing multiple pages hurts bandwidth (but alternatives could be worse); not to mention the server processing speed. Multiple requests for one page can add up. As for the "require_once()" and "include_once()" variables, advantages would include a page only being called once - for sure. Disadvantages include errors on trying to include that same page again.
