Modify the foreach command so that, as it loops through the books, it loads the ISBN for each book into a working variable called $isbn. At the same time, it should continue loading the title of each book into the $book variable
<?php
$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";

<title>Five Great Books</title>

<h1>Five Great Books</h1>
<ul>
<?php foreach($books as $book) { ?>
<li><?php echo $book; ?></li>
<?php } ?>
</ul>

isbn is the key, so you can just use the key => value style of the foreach loop
