The above is the nut you need, and you're doing it right. As Greg
pointed out, you'll need to change that from 'private $db' to 'var $db'
as PHP4 doesn't have member visibility. However, you're correctly
passing by reference -- something required by PHP4 if you want to share
the same object amongst several classes. (In PHP5, objects are passed by
reference by default, and the above code will actually generate some
notices -- but since you're developing for PHP4, you can safely ignore
them).
