Just found
PHPXref, a documentation generator for php applications. It shows include hierarchies and lets you follow functions from the file they're used in to the file they're defined in. It generates a set of HTML files to represent the application
It's good software in that although it's not the most comprehensive docs generating package ever, the ratio of what it demands in order work to what it delivers in functionality is very good. You can run it against any PHP application and get the cross referencing features. With a tiny bit of work formatting the comments on each function a certain way, it will pick up those as well.
It's written in perl, which I think is a perfect statement on the state of PHP.
bBlog has the docs generated by
PHPXref online
