I need help with my code challenge.

This is the task... First, we need to make the keys from the $books array accessible inside the foreach loop. Modify the foreach command so that, as it loops through the books, it loads the ISBN for each book into a working variable called $isbn. At the same time, it should continue loading the title of each book into the $book variable.

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

Prince Henry you can access the keys and values of an array in a foreach loop as follows:

<?php

$array = array(key => value);

foreach($array as $key => $value) {

}
