Array Keys Code Challenge quest 2

Hi Andrew,

Sure: I will try to enclose it in backticks so it will show up: Here's the question: "modify the code inside the foreach loop to display the $isbn in parentheses. After the title, add a space, an opening parenthesis, the ISBN, and a closing parenthesis."

my attempt <li><?php echo $book . ($isbn) ?></li>

Here's the response: 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)

It's showing up like this: Gilgamesh978-0743261690

I thought the answer had to do with displaying the parenthesis as a character and not part of the code.

Thanks!

Your problem is a syntax error. The problem asks you to add the ISBN, surrounded by parentheses, after the book's title. Since you are printing out the parentheses to the screen, you need make them a string. Add quotes around the parentheses and concatenate them with the $isbn variable. your code should look something like this:

<li><?php echo $book." (".$isbn.")";?></li>

Don't forget to add the space before the first parenthesis so that the php prints out a space between the title of the book and the first parenthesis.

Aha! Thank you!
