What are the best practices for handling nested HTML tags in PHP?

When handling nested HTML tags in PHP, it's important to properly parse and manipulate the HTML structure to avoid breaking the document's integrity. One common approach is to use a library like DOMDocument to load the HTML content, manipulate the DOM tree, and then save the modified content back as a string. 

// Example code snippet for handling nested HTML tags in PHP using DOMDocument

$html = '<div><p>This is a nested <strong>HTML</strong> structure.</p></div>';

$dom = new DOMDocument();
$dom->loadHTML($html);

// Manipulate the DOM tree as needed
$strongTags = $dom->getElementsByTagName('strong');
foreach ($strongTags as $strongTag) {
    $strongTag->setAttribute('class', 'highlighted');
}

// Save the modified content back as a string
$modifiedHtml = $dom->saveHTML();

echo $modifiedHtml;
