Help with getting and displaying the keys to the $books array

I am having trouble with this particular exercise. How do you get the keys of an array to display alongside their values in this code challenge for the $books array()? I am just not remembering the correct syntax of it I'm sure. Thanks.


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

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

Thank you, that seemed to work perfectly. I could not for the life of me figure that out.
