modify the code inside the foreach loop to display both the $title and the $isbn. After the title, add a space, an opening parenthesis, the ISBN, and a closing parenthesis, like this: Gilgamesh (978-0743261690)

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 $isbn => $book) { ?>
          <li><?php echo $book ." " .$isbn ; ?></li>
        <?php } ?>
    </ul>
</body>

At present, as in for an example, it is outputting as Gilgamesh 978-0743261690, at the closure of the challenge 1, 
you've been asked to output Gilgamesh (978-0743261690) for the challenge 2.

would you want to give it a try, yourself.

After the title, add a space, an opening parenthesis, the ISBN, and a closing parenthesis, like this: Gilgamesh (978-0743261690)

You just have to wrap the $isbn in parenthesis and you're good to go!
