Apache Zeta Components are a high quality, general purpose library of loosely coupled components for the development of applications based on PHP5. Beside typical modules for web application development like a template engine, database tools and an MVC component, Apache Zeta Components contain command line tools, a chart rendering library, a WebDAV server, a universal document conversion component and more tools to ease developers' lives.
Apache Zeta Components was originally developed by eZ Systems under the name "eZ Components" and was sponsored to the Apache Software Foundation for further development. Since 7/2010 the components have been known as "Apache Zeta Components." eZ Systems still builds their core products on top of Apache Zeta Components and contributes to the project.
