I have never found a prolem when using an interface was the only solution, or even ANY kind of solution.

You are wasting your time trying to implement fancy design patterns just because design patterns are supposed to be "cool". Loader class, Controller Base class, Front Controller - I have none of that crap in my code, so I don't encounter the problems you have. When I see code like "$this->load->library('email') " I just thank my lucky stars that I don't have to maintain it. I think some serious refactoring is long overdue. Perhaps you are trying to implement something from another language and expecting PHP to be just like that other language, which is always a stupid mistake. PHP is different, therefore the solution will be different. I suggest you learn how PHP works and design accordingly, and stop trying to force it into emulating another language. -- Tony Marston http://www.tonymarston.net http://www.radicore.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
