This is a PHP newsgroup, so I am explaining how interfaces work within PHP.
It is a simple fact that interfaces ARE NOT NECESSARY in PHP. The fact that
interfaces are treated differently in other languages is totally irrelevant.
The fact that YOU think that interfaces in PHP should behave exactly the
same as in other languages is also irrelevant.
