Browser redirect vs. download in virtual product link

[clevername]

I have a site that sells customized PDF forms. The forms are created via a PHP script that populates the resulting file with session information. s e x y, s e x y stuff.

I need to execute this PHP script via the virtual download link provided in the "checkout success" page after payment. However, my browser wants to simply download the PHP file, rather than execute it.

I'm sure there's a simple code tweak that would change this. Any ideas y'all?

I'm having exactly the same problem. Did you find a solution? If so, could you post it here?
