What are the best practices for embedding content in PHP without using <IFRAME>?

When embedding content in PHP without using <IFRAME>, one common approach is to use PHP's file_get_contents() function to fetch the external content and then echo it out directly onto the page. This allows you to embed external content seamlessly without the need for an <IFRAME> tag.

&lt;?php
$url = &#039;https://www.example.com/content&#039;;
$content = file_get_contents($url);
echo $content;
