In what situations is it recommended to use dynamic content embedding instead of header-based redirects in PHP, and how can this be implemented?

Dynamic content embedding is recommended when you want to display content from a different source within your website without redirecting the user. This can be useful for displaying external content, such as user profiles or product information, without disrupting the user experience. To implement dynamic content embedding in PHP, you can use functions like file_get_contents() to fetch the external content and then echo it within your HTML.

<?php
// Fetch external content
$external_content = file_get_contents('https://example.com/external-content');

// Display the external content within your HTML
echo $external_content;
?>
