PHP Object-Oriented PHP Basics (Retired) Inheritance, Interfaces, and Exceptions Inheritance to Interfaces

What is the interface keyword (bug?)

The question asks: "You use the (blank) keyword to use an interface on an class."

The lesson, transcript, and PHP docs all say the keyword is 'interface'. I'm getting an error every time. bang head

Is this a bug, or am I missing something totally obvious?

By the way, it should be "..on A class", not "..on an class". ;)

It looks like the question is asking for the keyword to use when you want to apply or implement an interface to a class.

The keyword, interface, is used when you are declaring the interface itself.

When you want to apply or implement the interface to a class you would use the implements keyword.

The question does seem to be worded a bit confusingly.

Ah, thanks, David! Missed the obvious, as suspected. :)
