Formatting not as expected?

I'm outputting the book title with the ISBN in parentheses after the title. How should it be properly formatted?


$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 $isbn => $book ) { ?>
            <li><?php echo $book;?> (<?php echo $isbn;?>) </li>
        <?php } ?>

Tried again with your suggestion, looks like that was the culprit. Thanks!

The code challenges can be very picky. It may work in real life, but if it does not fit the model answer the computer cannot tell it works.
