Any help would be appreciated. Stage 5 of Building a Simple PHP Application - Code Challenge.

If anyone can just solve for me that would be perfect. Having trouble wrapping my head around this. I may need a nap.

Hi Anthony,

Here is what I got inside the loop, this includes parts 1 and 2:

<?php foreach($books as $isbn => $book) { ?> <li><?php echo $book . ' (' . $isbn . ')'; ?></li> <?php } ?>

First you create the working variable $isbn within the foreach setup, then you concatenate the first space to a parenthesis using quotations, followed by your newly defined $isbn, then your closing parenthesis. Hope that helps!

Thanks, I actually went through everything again, and I got it correct. Just like what you wrote.
