Shouldn't this store the $key into the variable?

<ul> <?php foreach($books as $key $value) { ?> <?php $isbn = $key; ?> <li><?php echo $value; ?></li> <?php } ?> </ul>

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 $key $value) { ?>
          <?php $isbn = $key; ?>
            <li><?php echo $value; ?></li>
        <?php } ?>
    </ul>
</body>
</html>

Hi there Joshua!

Yes it should assign key value to the variable isbn. But in your foreach loop something is missing. 

foreach($books as $key => $value) { ... }

That should do the trick.

Best regards.
