Load key into a temp variable

Can you point me to the instructional video which goes over this type of challenge? I am completely lost here and have tried to backtrack through the previous videos in this lesson but I can't find where she goes over this.

The keys in this array are the ISBN of the books, it's asking me to load these keys into a temporary variable($isbn) within the foreach statement in order to display them along with the book titles, but I don't even know how to begin here and would like to go back over the lesson which went into detail.


$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";

    <title>Five Great Books</title>
    <h1>Five Great Books</h1>
        <?php foreach($books as $book) { ?>
            <li><?php echo $book; ?></li>
        <?php } ?>

Hey Ashlea Bowlin , In this code challenge you have to print book with isbn in browser windows so for the same result expected by the challenge you have to loop through $books along with keys and values.

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