Why is this not correct. It displays correctly!

It displays correctly, but the challenge tells me it does not!

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";

foreach($books as $isbn => $other){
  echo "( $isbn )";
};

?><html>
<head>
    <title>Five Great Books</title>
</head>
<body>
    <h1>Five Great Books</h1>
    <ul>
        <?php foreach($books as $book) { ?>
            <li><?php echo $book . " ($isbn)";
              ?></li>
        <?php } ?>
    </ul>

You don't need two foreach loops, the challenge is asking you to modify the existing foreach loop by establishing the $isbn variable so that you can access the ISBN and the title from the array:

<?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 $book . " ($isbn)"; ?></li>
        <?php } ?>
    </ul>
</body>
</html>
