PHPEdit supports almost all framework within Code Hint and Code Insight. You simply need to configure PHPEdit the right way.
To add support for Zend Framework:
1. Display the preference dialog (F10)
2. In Language -> PHP -> File dependencies, in the Include Path part, add the path to your ZF location, check the recursive checkbox, click on "Parse for cache", then Add.
You should now have all code hint and code completion for the framework.
