It doesn't work because - according to oop - every class should be
responsible for itself.
Since I don't know any possibility how objects could communicate to each
other, I'd try
the following:

simply instanciate the database-class as a class-member of the
users-class... then in the users-class
you should be able to say

$users->$db->sql_query(...)
I haven't tried that out, but IMHO it should work.

Hoping that I could help you,

greetings,

Gert.
