Well I managed to give bad info on this thread once so lets go for a second
shall we <grin>,
gzip does offer a option to output to stdout, instead of overwriting the
file, and if you piped it into a different filename(ie gzip -c source.html >
myzip.gz), but that's a total guess, although it should mean the original
isn't overwritten.

looking @ php.net, php has the wonderful ability to read zips but not write
them, isn't that nice<grin>

but I found a article which addresses what you want to do , except the page
with the php component seems to be having an error, the parent page is at
http://www.phpbuilder.com/forum/archives/2/2001/4/4/133961
the actual tutorial is at ...
http://www.zend.com/zend/spotlight/creating-zip-files1.php . google doesn't
cache the damn page, so perhaps they'll fix that page shortly[I sent a email
to their webmaster just now] in which case you can look there.
