PHP 5 introduces abstract classes and methods. An abstract method only declares the method's signature and does not provide an implementation. A class that contains abstract methods needs to be declared abstract.
Abstract classes cannot be instantiated. Old code that has no user-defined classes or functions named 'abstract' should run without modifications.
