The ZZIPlib library Gi Draheim: Download the ZZIPlib library
Zip PELC Extension: Download Zip PELC Extension
Install Linux system
PHP 5+: The zip functions and zip library are not enabled by default and must be downloaded from the link above. Use the -with-zip=direction configuration option to include zip code support.
Installation under Windows system
PHP 5+: The ZIP function is not enabled by default, so the php_zip.dll and ZZIPlib libraries must be linked from above. php_zip.dll must be enabled inside php.ini.
In order to enable any PHP extension, the PHP extension_dir setting (in the php.ini file) should be set to the directory under which the PHP extension library is located. For example extension_dir value is c:php extension.
