GZ troubles

[Anon]

I havent been able to get any gz function to work on my website.

i get
Fatal error: Call to undefined function:

I made this simple code just to test the gzfile function and it fails too.

$planets = gzopen("planet_listing.gz", "r");
$contents = gzread ($planets, 1000);
gzclose ($contents);
echo "$contents";

Looks like you didn't compile the zlib compression functions into PHP. PHP uses many external libraries to do it's work for it. It's one of the reasons the language has grown so fast. But to get access to those libraries you need to have them installed, and you need to tell PHP (during the compilation) that you have those libraries.
