When you create the items in the array, you are supposed to use commas to separate each line, not semi-colons.

<?php
$books = array (
978-0743261690 => "Gilgamesh",
978-0060931957 => "The Odyssey",
978-0192840509 => "Aesop's Fables",
978-0520227040 => "Mahabharta",
978-0393320978 => "Beowulf"
 ); 
?>

I Changed the semicolon into commas but now it is saying ISBN is not seen in the browser.

Hi,

leave the array as it was like this:

<?php

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

?>

I copy/pasted your code and got this error at first: Parse error: syntax error, unexpected ';', expecting ')' in C:\xampp\htdocs\today.php on line 4

Then I updated the array with commas instead of semi-colons and got this:

Five Great Books Gilgamesh (-1978812) The Odyssey (930) Aesop's Fables (977) Mahabharta (-88156750) Beowulf (975)

I assumed that was correct since it printed your foreach loop but just now I noticed the ISBNs aren't printing properly so I wrapped each key in quotes like it is a string and then got:

<?php
$books = array (
'978-0743261690' => "Gilgamesh",
'978-0060931957' => "The Odyssey",
'978-0192840509' => "Aesop's Fables",
'978-0520227040' => "Mahabharta",
'978-0393320978' => "Beowulf"
 ); 
?>
<html>

    <title>Five Great Books</title>

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

    </ul>
</body>

Five Great Books

Gilgamesh (978-0743261690) The Odyssey (978-0060931957) Aesop's Fables (978-0192840509) Mahabharta (978-0520227040) Beowulf (978-0393320978)
