I have a problem with the Code Challenge in Array Keys

If my memory is right it wants this: =>

An equal sign = and a greater than sign >

Try that

When we first learned the foreach loop, we just loaded values from the array into a working variable:

foreach($array as $values) {

Now, we want to change the code a little to load the values and the keys into working variables. We will need that double arrow operator, which is exactly what @Kevin says it is:

=>

Does that help?

I have done this:

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

But it throws me error. What am I doing bad? Please help me!

Thanks!

PROBLEM SOLVED!

Thank you Kevin Korte and Randy Hoyt for your response and help! I appreciate it a lot!!

I made these and everything was ok:

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