What are some alternative methods for including external content in PHP files for HTML display?

When including external content in PHP files for HTML display, one common method is to use the `include` or `require` functions. However, an alternative approach is to use the `file_get_contents` function to read the external content into a variable and then echo that variable within the HTML. 

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

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