In what situations is it more appropriate to use readfile instead of include for embedding HTML content in PHP?

When embedding HTML content in PHP, it is more appropriate to use readfile instead of include when you want to display the content of a file as-is without executing any PHP code within it. This is useful when you have static HTML content that you want to display without the risk of inadvertently executing any PHP code that may be present in the file. 

<?php
// Using readfile to display the content of a file as-is
readfile("path/to/file.html");
?>
