Code Challenge: Build a Simple PHP Application Integrating with PayPal Array Keys

For Task 2, I keep getting the error: "Bummer! 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)"

Here's what I have:

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

My output looks correct... what am I doing wrong?

You have extra space, or less space. check your spaces bro.

         <?php echo $book ."SPACE(".$isbn")" ?>

There's supposed to be a space there, but I think the issue might be the space after the <li> tag. Try this:

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

It's perfectly fine that you have a space there. I need to fix my test to ignore that: I wasn't expecting you to add a space there! Sorry for the trouble.

Hi Randy, I am getting the same issue. This is how I have it in the test. <ul> <?php foreach($books as $isbn => $book) { ?> <li><?php echo $book ." (". $isbn. ") "; ?></li> <?php } ?> </ul>

I am getting the same message as Steven Was.

How did you resolve it? I am having the same problem, even though the screen shows spaces with my code:

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

I am getting this message:

Bummer! 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)

Thanks in advance!
