DevShed:
Using Subclasses and Accessors with Member Visibility to Protect PHP 5 Class Data
Jun 05, 2008 @ 07:50:08

DevShed has posted the latest in their series of tutorials covering the scoping keywords in PHP5 (public, private and protected). In this latest edition they work with private values from a parent class.

In the last article, I explained how to work with a couple of private properties that partially comprised the API of a basic class, which is useful for saving simple strings to a specified text file.

This part builds on this previous example but changes up the subclass (an instance of DataSaver) to use what they call an "accessor" - a function in the parent that returns the private variable/contstant's current value when called.
