PHP foreach loops code challenge

can`t understand what is wrong here. Here is my code here is the response I see all the book titles and the ISBNs in the browser, but the formatting is not quite right. Each list item should look like this: Book Title (978-0123456789)


$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 . " " . "(" . $isbn . ")" ; ?></li> 
        <?php } ?>

what could be the problem?
