How do I load in the $isbn at the same time as $books as $book?

Below is what was already there. Here is my proposed code which failed

Proposed code:

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

<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>

Your foreach code is wrong. The foreach criteria is: $books as $isbn=>$book.

That takes the $books array and loads the keys of the array elements into a working variable called $isbn, and loads the values of the array elements into a working variable called $book.

For part 1 of the challenge, this is the code:

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

For part 2 where you have to concatenate the isbn in the echo output, use this.

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