How can the PHP code be modified to ensure that the array contains the expected content from the div class?

The PHP code can be modified by using the DOMDocument class to parse the HTML content and extract the desired data from the div class. This involves loading the HTML content into a DOMDocument object, locating the div class using XPath, and then extracting the text content of the div class. 

// HTML content containing the div class
$html = '<div class="content">Expected Content</div>';

// Create a new DOMDocument object
$doc = new DOMDocument();
$doc->loadHTML($html);

// Use XPath to locate the div class
$xpath = new DOMXPath($doc);
$divContent = $xpath->query('//div[@class="content"]');

// Extract the text content of the div class
if ($divContent->length > 0) {
    $expectedContent = $divContent->item(0)->nodeValue;
    echo $expectedContent;
} else {
    echo "Div class not found";
}
