Try

<?php for each($books as $isbn => $book){ echo "<li>" .$book[$isbn]." "." ($isbn) "."</li>"; ?> }

Hello,

You don't need the $book[$isbn] as the variable $book is the value containing the name of the book. The following is the complete syntax for the foreach statement:

foreach($array as $key => $value)

Cheers!
