Lost on loading the key into a variable

I have watched the videos over and over and cannot for the life of me figure out how to load the key into a variable.

I figured it out. I realised I need to load the key into the variable using the following syntax:

<?php foreach($books as $isbn => $book) { ?>

Was there a video that helped you "get" this. I was struggling to understand it. I always try resist just putting in an answer from the forum, but I was really getting no where. Any links would be appreciated.

You got it, by default, foreach gets the value of the key so you need to stipulate you want the key as well and then it's just echo $isbn to get it.
