What best practices should be followed when parsing and modifying HTML links in PHP?

When parsing and modifying HTML links in PHP, it is important to use a reliable HTML parser library such as DOMDocument to ensure proper handling of HTML elements. This will allow you to easily locate and manipulate links within the HTML document without breaking the structure. Additionally, make sure to sanitize any user input before modifying the links to prevent XSS attacks. 

// Load the HTML content into a DOMDocument
$html = '<a href="https://www.example.com">Example Link</a>';
$dom = new DOMDocument();
$dom->loadHTML($html);

// Find and modify all links in the HTML
$links = $dom->getElementsByTagName('a');
foreach ($links as $link) {
    $link->setAttribute('href', 'https://www.newlink.com');
}

// Get the modified HTML content
$modifiedHtml = $dom->saveHTML();
echo $modifiedHtml;
