Subject: Calling original function from an overloaded function
From: christoph@christophdorn.com (Christoph Dorn)

I have been looking at xdebug and have figured out how to overload a
function. As a test I have overloaded the var_dump function.

Now how do I call the original var_dump function from my implementation?
Borrowing from OO terminology I have subclassed the var_dump method, now
I want to call parent::var_dump() from my subclass.

Also how does overloading work when two extensions overload the same
function? Can this be done? Is there some sort of order? Can I let the
other extension overload the function and then overload the function
from the other extension?

Any pointers would be greatly appreciated.

Thanks

Christoph
