Generate class diagrams from PHP classes automatically?

I have build a web application in Zend Framework and now desperately need a tool/plugin which can generate class diagram from all of my Zend Controllers (Classes).

I uses Zend Studio and Eclipse so if you know any plugin which does the job then please do let me know.

All help and comments are really appreciated.

Many Thank开发者_运维技巧s Vishal

autodia is easy to use if a bit basic. It handles a range of languages and makes a nice job of mySQL as well.
