zip files using php?

How do you zip files using php? i know you need to use a form where the type is file so that you can browse for the file. Other than that i dont know what to do. Help

PHP ships with an extension zip.so
It contains read-only functions for Zip files... this means you can read/open Zip files...
You can't [natively] create zip files.

There is an Apache extension, i believe called mod_gzip which i believe will allow you to compress files on-the-fly...
I've never used it though...

ok. i get it. basically u can't zip a file without the extension you gave in your reply but you can read/open a zip file. that make sense heheh thanx

After i get the above problem solved, how do i create a pop-up to allow the user to specify the name of the file being zipped?

actually i wanted to know how to create an input dialog via php. do use a javascript to do that? if so, how do you do it?

There are a ton of ways to do this... check this page for a lot of ideas: http://us2.php.net/manual/en/ref.zip.php
