hi,

twigletmac is correct, google.com is the best resource for search...

Anyway:
Gzip is GNU data compression program.

PHP also has facility for reading/writting gzip files through Zlib Compression Functions.

Just by the name, you could predict it was some form or related to zip. ;)

I never really bothered to learn much about it, since my work has not brought me in any contact with it. But i will soon, and when i do, there is great articles about it and other info on tutorial sites. Here is a bit off there site...
Introduction to Gzip

gzip (GNU zip) is a popular data compression program written by Jean-Loup Gailly <gzip@gnu.org> for the GNU project. Mark Adler <madler@alumni.caltech.edu> wrote the decompression part.

We developed this program as a replacement for compress because of the UNISYS and IBM patents covering the LZW algorithm used by compress. These patents made it impossible for us to use compress, and we needed a replacement. The superior compression ratio of GZIP is just a bonus.

For versions of GZIP for MSDOS, Windows or the Macintosh, see Gailly's gzip page.

The format of the .gz files generated by gzip is described in RFCs (Request For Comments) 1951 and 1952.

Online Manual is available at www.gnu.org/manual/gzip/index.html

hi,

Gzip is by default available on (red hat) linux.
man gzip
will give command details, options etc.

There is one more package in (red hat) linux - bzip2 - which is better than gzip in data compression !!
man bzip2
for details, options etc.

GZIP's got quite a good compression ratio. You can include the extension in PHP by editing php.ini 8O

P.S. I don't say Google is the best search engine cos I've heard of a better one (don't ask me the name, I forgot... But I know it's still in BETA version).
