Re: PHP OOP Question

From Practical PHP Programming:
Quote:
There are a number of special keywords you can place before a class, a class function definition, or a class variable to alter the way PHP works with it - here's the full list, along with what each of them does:

* Public: This variable or function can be used from anywhere in the script
* Private: This variable or function can only be used by the object it is part of; it cannot be accessed elsewhere
* Protected: This variable or function can only be used by the object it is part of, or descendents of that class
* Final: This variable or function cannot be overridden in inherited classes
* Abstract: This function or class cannot be used directly - you must inherit from them first
The wiki also gives examples for you.
