writing to frames with php

[feigenblatt]

Is there any way of creating a frameset and write to the frames in one pass?
I'd rather keep all the frame contents in a single script.

I thought of two ways of doing it, but haven't tested them yet.
One way would be to call the same script for each frame, passing a GET variable or TARGET on the URL to control the output.
Another way would be to generate the contents of the frames into javascript functions to be executed on onLoad of the frameset. I don't even know if that's possible.
But I don't like either way.

Does anybody have any thoughts on this subject?

Thanks.
