Interface usb{
function mount ();
function work ();
function unmount ();
}

Class diannao{
function Useusb ($USB) {
$usb->mount ();
$usb->work ();
$usb->unmount ();
}
}

Just learned class, so in the value of a bit random, here unmount () is not to tune the interface method, because in this class do not see the declaration.

Yes, but you should be missing a class, this kind of need to inherit the USB interface implementation inside the method, and then the class as a parameter to the Computer class function Useusb (USB $usb) {} method inside.
