How can absolute URLs be generated from relative URLs when retrieving an external website's content in PHP?

When retrieving an external website's content in PHP using relative URLs, these URLs may not work correctly when displayed on your own website. To ensure that all URLs are absolute and work properly, you can generate absolute URLs by combining the base URL of the external website with the relative URLs.

php 
// Base URL of the external website
$base_url = 'https://www.externalwebsite.com';

// Relative URL retrieved from the external website
$relative_url = '/path/to/page';

// Generate absolute URL
$absolute_url = $base_url . $relative_url;

echo $absolute_url;
