How can partners include the content of a website in their own layout using PHP?

Partners can include the content of a website in their own layout using PHP by using the `file_get_contents()` function to retrieve the content of the website and then echoing it within their own layout. They can also use cURL to fetch the content of the website if needed.

<?php
// URL of the website to include
$url = 'https://www.example.com';

// Get the content of the website
$content = file_get_contents($url);

// Echo the content within the partner's layout
echo $content;
?>
