What are some potential methods in PHP to parse HTML source code?

When working with HTML source code in PHP, one common task is to parse the code to extract specific information or manipulate the structure. One way to achieve this is by using PHP libraries like Simple HTML DOM Parser or DOMDocument, which provide functions to easily navigate and manipulate HTML elements. These libraries allow you to load an HTML source code, traverse the DOM tree, and extract data based on tags, attributes, or classes. 

// Using Simple HTML DOM Parser
include('simple_html_dom.php');
$html = file_get_html('http://www.example.com');
$element = $html->find('div[id=content]', 0);
echo $element->plaintext;

// Using DOMDocument
$html = file_get_contents('http://www.example.com');
$dom = new DOMDocument();
$dom->loadHTML($html);
$element = $dom->getElementById('content');
echo $dom->saveHTML($element);
