How object orientated can you make a website?

[JonD]

I was thinking before that I hardly have any classes on my website (php), only a database class that is really used.

For example take the well known gaming site: http://www.sk-gaming.com/, or any other.

Now by looking at these sites I cant get my head around how object orientated you can make them.

I want to be able to get all my sites into 1 class that creates instances of other classes inside it.

Is it possible to get the entire site into classes?

Yeh i know, but what actual classes can u actually define on a site such as the one above?
