PHP Build a Basic PHP Website Listing and Sorting Inventory Items Array Keys

I cannot get past this exercise

I have already assigned the key to isbn but it says my foreach statement needs to assign the key to a temporary variable named $isbn.

index.php
<?php

$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";

?><html>
<head>
    <title>Five Great Books</title>
</head>
<body>
    <h1>Five Great Books</h1>
    <ul>
        <?php foreach($books as $key => $book) { ?>
            <li><?php echo $book;
                 $isbn = $key;
              ?></li>
        <?php } ?>
    </ul>
</body>
</html>

Why not have the loop extract the key directly into the $isbn variable, then you wouldn't need $key at all (or the need to reassign it later)?
