PHP, GZIP

Hi list,
 
I'm using mod_layout on an apache 1.3.29 and everything goes fine except one
little thing.
 
There are pages in PHP witch uses GZIP to compress themselfs, and when I
appli a header and/or a footer, the page displays the header and/or footer
and ASCII characters (presumely the GZIPped page!), as you can se in this
link:

How can I display banner and the page correctly?
 
Thank you
