How to add an export function to a custom Option Theme Page

I’m creating a new WordPress template and I have a question:
I’ve added a custom Option Page to my new template (you can see what I’m doing Here and Here) but now I would like to add a new function.

I would like to be able to add the same function into my new option page.
I know how to backup my settings logging to phpMyAdmin but sometimes end-user can’t login to phpMyAdmin or simply it’s better that he/she doesn’t login to phpMyAdmin :-).
Have you got any solution to this?

Thank you very much to all!
