Make a .txt database?

Hi, I’m working in a new project that needs to store some numbers world wide, but not using a MySQL database or stuff like that. I’d like to use a text file.

The thing goes like this:

A user enters the flash page, where he clicks a “+” button that adds 1 to a variable that will keep growing. Then the user will be able to click on another button that says “add to total worldwide”, that will hopefully add the amount displayed to a number stored somewhere in a text file. Then that total will be loaded in the same file.

In that way, a lot of people around the world will be able to add clicks to the total ammount. I’ve seen txt files storing variables such as the one of the hitcount tutorial… any idea how to do it? Please help!

Thankuuuuuuuu!
