WP-ZFF will put the Zend and ZendX libraries in the include path and will autoload the classes when they are needed. Plugin developers will not have to worry about including any files. The libraries will use the Zend autoloader so no additional including will be required for plugin developers.
Zend Framework is an open source, object-oriented web application framework implemented in PHP 5 and licensed under the New BSD License.
Note: Requires PHP 5.2.4 or later
See changelog for update. Changed the way autoloader is loaded, should be more compatible.

WP-ZFF Zend Framework Full

WP-ZFF Zend Framework Full will make the latest Zend and ZendX libraries available for any plugin to use simply by calling the class name.
