What are the best methods for including external webpages using PHP or SSI while maintaining links and image properties?

When including external webpages using PHP or SSI, it is important to maintain the links and image properties of the included content. One way to achieve this is by using PHP's file_get_contents() function to retrieve the external webpage's content and then parsing it to extract and display the necessary elements such as links and images. 

<?php
$url = 'https://www.externalwebsite.com/page.html';
$html = file_get_contents($url);

// Parse the HTML content to extract links and images
$dom = new DOMDocument();
$dom->loadHTML($html);

// Get all links and images from the parsed content
$links = $dom->getElementsByTagName('a');
$images = $dom->getElementsByTagName('img');

// Output the links
foreach ($links as $link) {
    echo '<a href="' . $link->getAttribute('href') . '">' . $link->nodeValue . '</a><br>';
}

// Output the images
foreach ($images as $image) {
    echo '<img src="' . $image->getAttribute('src') . '" alt="' . $image->getAttribute('alt') . '"><br>';
}
?>
