What are the best practices for ensuring server information is included in the HTTP header in PHP?

To ensure server information is included in the HTTP header in PHP, you can use the `header()` function to set custom headers. This allows you to send additional information along with the response, such as server information or other metadata. By setting custom headers, you can provide useful information to clients or other servers accessing your PHP application. 

<?php
// Set custom header to include server information
header('X-Server: PHP Server 1.0');
?>
