How can the DOM structure be utilized to effectively manipulate HTML content in PHP?

To effectively manipulate HTML content in PHP, the DOM structure can be utilized by using the DOMDocument class. This class allows for easy traversal and manipulation of HTML elements, attributes, and text nodes within a document. By loading an HTML string into a DOMDocument object, various methods can be used to modify, add, or remove elements before outputting the updated HTML content. 

// Create a new DOMDocument object
$doc = new DOMDocument();

// Load the HTML content into the DOMDocument
$doc->loadHTML($html);

// Find and modify elements using DOM methods
$element = $doc->getElementById('myElementId');
$element->setAttribute('class', 'newClass');

// Output the updated HTML content
echo $doc->saveHTML();
