Encapsulation is NOT data hiding. Take a look at http://www.javaworld.com/javaworld/jw-05-2001/jw-0518-encapsulation.html http://www.itmweb.com/essay550.htm http://c2.com/cgi/wiki?EncapsulationIsNotInformationHiding > you might also want to read about how interfaces are used because it > sounds > like youre confused. they are not needed to call methods, they provide an > alternate mechanism for polymorphism. But I don't NEED interfaces in PHP. My code runs perfectly witout them, therefore I see no reason to use them. They require extra work for no benefit, so there is no point in using them. I do not need an alternatve method for polymorphism as the one I currently use is more than adeqate. Interfaces are used in other languages because of deficiencies in those languages. PHP does not suffer from those deficiencies, therefore does not need interfaces in order to function. > you can find the basics in an entry level > text, and more sophisticated topics in a design patterns text. > i recommend the heads first book.

OO code does not need private/protected/public in order to function. It does not add any functionality, it merely imposes restrictions. PPP is totally cosmetic, a complete red herring, and a waste of time as far as I am concerned. -- Tony Marston http://www.tonymarston.net http://www.radicore.org > -nathan > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
