What is the difference between using include() and require() in PHP when including files from a remote URL?

When including files from a remote URL in PHP, it is important to use require() instead of include(). The require() function will cause a fatal error if the file cannot be included, while include() will only produce a warning. This ensures that the script execution stops if the remote file is not accessible, preventing potential security risks. 

<?php
require('http://example.com/remote_file.php');
?>
