Re: Scope of variable in Class

Thank you for the quick respond. Is there any suggestion how can I effectively "shoot" a user that accesing my prefix 'private' variables other than doing code review? I'm actually developing an API/wrapper using classes. The users that are using these classes should not be allowed to access some of the 'private' variable (ie. for security reason) from their program. Unfortunatelly, until now I allow them to look at the API. Reuben D. B At 07:37 PM 11/6/00 -0800, Lars Torben Wilson wrote:

         }

} I can access (ie. print) $items by doing: $myCart = new Cart; echo $myCart->items; My question: is there any way so that someone can NOT access $items? in order words, make $items a PRIVATE variable for the class only? Thanks Reuben D. Budiardja No. You could always just prefix 'private' variables with an underscore or something and tell users that anyone using '->_' unless it immediately follows a '$this' will be shot, but that's about it. -- +----------------------------------------------------------------+
