java or PHP 5.0 question about interfaces

Do interfaces enforce how many arguments can be passed to a method? If
two classes inherit from the same interface, can one have
formatThisText($text) and another have formatThisText($text,
$formatter) ??? I'm assuming the answer is yes, interfaces do enforce
the number of arguments.

Concerning JAVA you are right. Interface enforce the number
of parameters, their types, the type of the returned value
and even the method's visibility.

Thank you for the reply. That is what I would expect in Java. Does
anyone know the answer for PHP 5.0? Or where that information is
documented? I noticed a bunch of very interesting articles here
(though they didn't answer my question):

PHP is truly become a script version of Java, with a nearly complete
imitation of Java's object features, minus strict typing.

Still, I'm wondering about interface enforcement in PHP 5.0 and can't
find an answer.

Another question I have is can an argument passed to a method have a
default value in one object but a different default value, or none, in
another object if both inherit from the same interface?
