7,507 PointsDear, I pass the first challenge, but when I look at the preview my array_keys has generated an error
Dear
the first challenge I passed by
foreach($books as $isbn => $book) {echo $books; echo array_keys($isbn);}
however when looking at the preview I get an error saying parameter needs to be an array, so obviously the code was wrong yet I passed the challenge.
How do I get
a the keys to be displayed b where can I write $title
Best regards,
Mirko

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