I think what you want are frames, like this site does:
http://www.reversephonedirectory.com/
I believe about.com often does the same thing.
Just study their code for a few minutes and I think you'll have all you need to know.
You basically just build your frame and have all outside links put in the other frame.
If this isn't what you need then you'll have to use the fopen line of functions and parse your data into the resulting file, then display it out.
