What steps can be taken to troubleshoot when the host information is not being displayed in PHP?

If the host information is not being displayed in PHP, it could be due to incorrect server configuration or a problem with the PHP code itself. To troubleshoot this issue, you can check the server settings to ensure that the host information is being properly passed to the PHP script. Additionally, you can review the PHP code to make sure that the host information is being correctly accessed and displayed. 

<?php
// Check server settings to ensure host information is being passed
echo "Server Host: ".$_SERVER['HTTP_HOST'];

// Review PHP code to ensure host information is correctly accessed and displayed
?>
