Give me a hint. I know my foreach needs to assign the array key as a variable...

I know the foreach needs to assign the array key as a variable, and I probably need to use the array_keys() function, but I don't know where or how, or even where to look for help. This sucks.

index.php
<?php

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

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

Heres a way you can do it with using foreach($books as $isbn => $book

<?php

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

?><html> <head> <title>Five Great Books</title> </head> <body> <h1>Five Great Books</h1> <ul> <?php foreach($books as $isbn => $book) { ?> <li><?php echo $book . " (" . $isbn . ")"; ?></li> <?php } ?> </ul> </body> </html>
