Zend framework might not be as popular as other famous programming frameworks such as CAKE PHP or symfony. But still it's getting quite usable with version 1.7 approaching and a growing number of serious of libraries are hitting the ground. We've already covered code generation, scaffolding and RAD with Zend framework in previous articles, this article covers lower level libraries from Zym Projet
Zym Project includes a powerful navigation abstraction that can help building pages hierachy in a CMS application for example. Other goodies include the bootstrap class, that takes all configuration from ini files (bootstrap class also exists in another ZF extension, ZENDEX). Some classes of Zym Project have been integrated into 1.6 official release of Zend Framework. API classes Reference guide is available online.
