What have you tried so far? What happened?
I assume you're on shared hosting. This means that you may need to get some more information from their end to know exactly what settings to change.
In my case f'rinstance I didn't have to change anything. I just shoved a php file into the "include" line and it worked. Fortunately nobody had told me that it might not ;) Well, except that my system doesn't like "include virtual" followed by a relative URL. It insists on a leading slash to make it site-absolute. (I think technically it went the other way around. Relative links work with "include" alone; absolute links need the "virtual" bit.)
Now, including other stuff inside php... that gets tricky.
