I need to send some variables from flash to php. I'm lost

I have a simple banner that has three choices. A, B, and C. When a user clicks on one of the choices…I just need a counter to make note of it…in some remote file. Php I would guess.

So the end result is that you could access the php file and see that choice A was clicked however many times, and choice B was clicked so many times, etc.

But I am not a Php guy and don’t know what syntax to use to make this happen.

I would appreciate any help…Thanks.
