I know that PHP 5.x comes with zip functionality (turned off?), but I don't know how to make it work. When I try to use it in a script it can't find ZipArchive. I've tried $zip = new ZipArchive; and $zf=zip_read($zip); but nothing. I don't know how to configure the system for reading zip files. This is my first pass at PHP (Ive been doing ANSI-C code for 30 years). I'm using your environment as follows:
he following components are installed:

* Apache 2.2.6
* OpenSSL 0.9.8g
* Mod Perl 2.0.3
* Mod WebDAV 2.2.6
* Mod SSL 2.2.6
* PHP module 5.2.5
* NuSphere PhpExpress 1.4.2
* Perl 5.8.2
* NuSphere PHP Debugger DBG 3.2.12
* Apache 2.2.6
* OpenSSL 0.9.8g
* Mod Perl 2.0.3
* Mod WebDAV 2.2.6
* Mod SSL 2.2.6
* PHP module 5.2.5
* NuSphere PhpExpress 1.4.2
* Perl 5.8.2
* NuSphere PHP Debugger DBG 3.2.12

Never mind- I was editing the wrong php.ini file to activate the zip functions.
