What are the benefits of using DOM manipulation for replacing HTML tags in PHP?

When replacing HTML tags in PHP, using DOM manipulation provides a more robust and reliable way to modify the structure of the HTML document. It allows for easy traversal and manipulation of the DOM tree, making it simpler to target specific elements for replacement. Additionally, DOM manipulation ensures that the changes made to the HTML document are well-formed and adhere to the document structure rules. 

<?php
// Create a new DOMDocument object
$dom = new DOMDocument();

// Load the HTML content into the DOMDocument
$dom->loadHTML($html_content);

// Find the element to be replaced using getElementById, getElementsByTagName, etc.
$element_to_replace = $dom->getElementById('element_id');

// Create a new element to replace the existing one
$new_element = $dom->createElement('div', 'New Content');

// Replace the existing element with the new element
$element_to_replace->parentNode->replaceChild($new_element, $element_to_replace);

// Save the modified HTML content
$modified_html = $dom->saveHTML();
?>
