In order to run the ads by my provider I have to insert the following code in my shtml pages:
<!--#exec cgi="/banner/banneradventure.cgi"-->

However, I just set up a PHP-based forum and would like to show my ads there as well. The code above doesn't seem to work. Is there a PHP alternative to server side includes? Since it's a server-side language, I'm pretty sure there must be

Thanks in advance
