  • The Zip PELC extension: Download the Zip PELC extension

Installation on Linux Systems

PHP 5+: Zip functions and the Zip library is not enabled by default and must be downloaded from the links above. Use the –with-zip=DIR configure option to include Zip support.

Installation on Windows Systems

PHP 5+: Zip functions is not enabled by default, so the php_zip.dll and the ZZIPlib library must be downloaded from the link above. php_zip.dll must be enabled inside of php.ini.

To enable any PHP extension, the PHP extension_dir setting (in the php.ini file) should be set to the directory where the PHP extensions are located. An example extension_dir value is c:\php\ext.
