Re: Data Hiding Implementation in PHP Classes

We also have public as an alias for variable. marcus At 15:09 16.08.2002, Brad LaFountain wrote:

Hello, My question is if there is anyone working on an implementation of data

hiding in php? IE Public, private, and protected data types within php classes. I can not find anywhere mentioning this besides very few websites that say it is on the "TODO" list.

The research that I'm doing involves dynamically programming php from the

internet collectively with many users, of which some would have restricted access rights to specific objects. All objects would have certain data that I would need to be of type private, ie owner id, permission mode, etc... in order for the object security model to be safe. Without data hiding any user using this system could simply type $Current_User->UID=0 which would then change the owner of this object, which happens to be a user to 0, or god. There may be a different way to implement this that I'm not seeing, but any model that I come up with in php I can circumvent by some simular means.

I may need to implement a servlet in java that keeps track of currently

logged in users and objects in memory, but this would be more overhead than wanted. If data hiding was implemented in PHP I would be very excited. If there is not already someone working on it, perhaps I will roll up my sleeves and get my elbows dirty.
