The array below contains a list of books. Each element in the array has the book’s title as its value and the ISBN as it

I've been on this one for a couple days now. Really confused! If someone wouldn't mind helping me that would be awesome!

Hello,

They are asking you to modify the foreach() loop to include the array keys and then take that array key and put it into a variable called $isbn. Remember, you can use a foreach loop one of two ways: foreach($array as $value) and foreach($array as $key => $value). Once you allow to loop to use the array key, just assign it to the variable $isbn or if you named the array key in the loop $isbn, just add another $ to the front of it like so: $$isbn. Hope I helped you enough for you to get it without giving you the direct answer.

Cheers!
