PHP foreach loops / array keys code challenge

Hallo, I don't understand what is wrong here. Here is my code and here is the response:

I see all the book titles and the ISBNs in the browser, but the formatting is not quite right. Each list item should look like this: Book Title (978-0123456789)

<?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>

Your look looks fine, I just ran it on my localhost. Could you please tell me which badge and the name of the code challenge this is from. I couldn't find it and I believe that the error might have something to do with the formatting of you answer and not a syntax error in your code.

Hi there,

Thanks for the quick reply.

It's 'Intergrating with PayPal badge' and the challenge is: 'Code Challenge: Array Keys'

Your code still looks right, but it looks like the challenge is also looking for the html markup as well. So what you need is:

<?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>

So your code was right, but the program that checks that challenge was looking for the correct markup as well. Hope this helps.
