Hi Murtaza, I haven't done the course and I dont know how much you have learned so far, but i would do it this way.

All i have done is ($isbn => $book) - What it does is that it loads the key from the $book variable into the variable named $isbn.

$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";

<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>

Thanks Rune . I got it :-)
