include a CGI file in PHP with variable

[Anon]

I have an affiliate tracking software made in cgi that I want to call within a PHP file.

How would I call it while passing on a variable from the URL.

For example, my website URL will bE:

http://www.website.com/?user=name

I want to pass the "user" variable on to the cgi program that I will call within the PHP page.
