Ey, I'm working on a large project but I don't have any idea of how to make my classes properly. I have to make Microsoft Office Word file from php and it works but the classes aren't any good designed so I'm working on V2 now.

Here a screen of a piece of the UML to give you an idea.

Explanation of the UML. It is possible to add text, paragraphs and/or images to the word document itself. But it must also be possible to add a header and/or footer and add text, paragraphs and/or images to the header/footer.

I thougth of makeing a get/set class for text, paragraphs etc.. and then read it all in the WordDocument class en generate the right xml.

But don't know how I can work this out in php, anyone who can help me out the basics?
