Reverse engineering "prototype" from PHP extension?

[Jason Birch]

Hi all,
 
I'd like to set up "intellisense" for the MapGuide php extension in my php editor (PHPEd), but in order to do this, I need to make a PHP file that contains a prototype for all of the classes, methods, properties, constants, etc available through the MapGuide Web API.  This isn't something that I really want to tackle by hand :)
 
Can anyone think of a way that I can automatically generate this kind of file?
 
An example of what I need to generate can be found on the PHPEd website:

Thanks,
