Subclassing versus referencing

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm sorry if this is a basic OOP question, but I've held off against OOP for the last 10 years and finally I've given in. So far, I like. It's made my life a *lot* easier and my code a lot cleaner. I've built an object for the main operations and state of my application. And I've included a reference to the DBDO in it. But after doing it this way for a few weeks, my code is riddled with $donation->obj->fieldname and $user->obj->joinAdd($donation->obj) and other such ugliness. Is there any general rule as to whether and when I should subclass? I was mainly worried about collisions-- since the bare fieldnames are vars in DBDO-- but I've already taken the FB approach on some vars, and added them to the DBDO as $kr_thing, and I suppose I could just keep doing that. - -ken - -- - --------------- The world's most affordable web hosting. http://www.nearlyfreespeech.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) iD8DBQFB26dwe8HF+6xeOIcRAix4AJ4tZagHEzXyLk20GUGVpz/T1hAe1ACfTxDP Lnk30zC0mDoCDwS1rL6tcMo= =acVE -----END PGP SIGNATURE-----
