OK, so I was reading this post and I have a feeling that my question can 
be answered as an ongoing continuation of this post.

I understand Object Oriented Programming in places such as a daemon, or 
when you're writing a game in java that constantly continues to run.

But I don't understand the use of Object Oriented Programming in 
scripting.  Once the page is loaded, a new instance of any object you've 
created must be re-created (unlike java where you can create a game and 
constantly interact with the same data set).

So my main question is:  Why do people use object oriented programming in 
websites?

Thanks! :)
