In the quiz after this video, a question asks how to properly access the "price" property of a parent class. I don't understand why "parent::price" is correct, isn't that syntax for accessing static variables only? Why does "price" not have a "$" in front of it if that's the case?
I thought the correct answer would be "parent -> price" but it was not. I am very confused.

Using parent:: has always been the customary way to access the parent class from classes that inherit the parent. Here and here are how php.net explains things. As Ted specified, I too believe that the $ is an error with the quiz as in the past I've used the $ to access parent properties.
Cheers!

He clearly states that the object operator does not work in that video, but his example includes the $. I will have to play with this more when I have some time.

4,001 PointsThank you!! After reading those pages it cleared things up. I was confused since the quiz didn't specify if "price" was a static variable.
