Subject: problem with interfaces
From: cunha17@uol.com.br ("Cristiano Duarte")

Hi all,

Is this supposed to work?

interface test {
    function my_function ($mandatory_parameter);
}

class test_class implements test {
    function my_function ($mandatory_parameter, $optional_parameter = null)
{
    }
}

The test_class class implements correctly the 'test' interface since PHP
does not allow multiple explicit method declarations (explicit overloading).

IMHO, if all additional parameters are optional, the interface commitment is
preserved.
