Is it possible to have an interface that has private / protected methods?

Question

Is it possible in PHP 5 to have an interface that has private / protected methods?

Right now I have:

interface iService
{
    private method1();
}

In many cases, an interface definition helps other modules guarantee the behavior and the API of a class. In those cases, private methods are not something the other modules can access or understand. That's why you can never put private methods on an interface.
