PHP and CGI

I'm using a php include setup for my website...

include("header.php");
include($page);
include("footer.php");

How do I get a CGI script to become $page with a variable?

I know about exec and successfully printed the cgi output, BUT I need to send a variable to the CGI which affects the output.

In this instance it is a domain name to a whois CGI, which needs to be included in a php.

I'm sending more than one variable to the CGI, "ext" and "domain" are the vars

OK I've sorted it...

I wrote the vars to a file under php, then when the CGI runs, it opens the file itself and gets the vars.

Cheers if U even read this =[

You could use fopen() and treat the CGI program as a web document; something like fopen("http://localhost/cgi-bin/program.cgi?ext=something&domain=somethingelse","r");

For exec()ing it, if I recall rightly the CGI protocol has GET-requested data supplied as a command-line argument.
