Generate UML from Zend-framework project?

Are there any tools for generating UML diagrams from an existing Zend framework project? Something that detects all classes in specific folders. I don't want the Zend classes to be included because it would become to large and messy, only the classes that I've created...

Any ideas?

I use Netbeans as IDE, so if it's开发者_如何学编程 actually possible within Netbeans that would be awesome!

Thanks!

BoUML does the job quite nice with reverse engineering (http://bouml.free.fr/), although I hope I don't need to tell you to make the UML up front
