PHP

Need to make changes in foreach loop so it displays isbn.

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

What is wrong?

books.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 $isbn => $book) { ?>
            <li><?php echo $book; ?></li>
        <?php } ?>
    </ul>
</body>
</html>

Hi Martin,

You're almost there. You just need to include the space and parenthesis within quotes, e.g.

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

Hope that helps.
