I am trying to modify some methods of the class in the subclass but I get the following error:

Fatal error:  Declaration of Filme::create($name, $year, $poster, $description, $genre, $trailer, $download) must be compatible with InterfaceMedia::create($name, $year, $poster, $description, $genre, $trailer) in /var/www/html/cinetor/class/php/ClassFilme.php on line 20

    You entered a parameter $download which is not defined in the interface. You should remove it or add it to the interface if you have forgotten. The parameters should be exactly the same.

Interface is like a "contract". The interface defines what the MUST class has.

In the method create() class Filme{}, there is an additional parameter ($download) relative to the same method defined in the interface.

Remove this parameter or add it to the interface.

example:

interfacemedia interface {

public function load($id);

public function drop($id);

public function create($name, $year, $poster, $description, $genre, $trailer, $download);
