Ah, yeah I know what you mean. You want the PHP equivalent of "vardump".

I'm not aware of anything that does it, but it would be easy to make, by
extending on dir:

def inspectobj(obj):
    return dict(map(lambda x: (x, getattr(obj, x)), dir(obj)))

pprint.pprint(inspectobj(django.db))
pprint.pprint(inspectobj(str))
pprint.pprint(inspectobj(django))

This is very very very basic, and you'd need to add all sorts of
conditionals in there to make it extract the information you want in a
proper, recursive fashion (and telling it how to deal with unbound methods
etc), but it's a start.

Enjoy :)
