What are best practices for manipulating and processing HTML code retrieved with PHP functions?

When manipulating and processing HTML code retrieved with PHP functions, it is best practice to use PHP's built-in DOMDocument class. This allows you to easily parse, manipulate, and extract specific elements from the HTML code. By using DOMDocument, you can ensure proper handling of HTML entities, tags, and structure. 

// Retrieve HTML code
$html = file_get_contents('https://example.com');

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

// Manipulate and process the HTML code as needed
// For example, extract all <a> tags
$links = $dom->getElementsByTagName('a');
foreach ($links as $link) {
    echo $link->getAttribute('href') . '<br>';
}
