I need to grab the host name from the URL. I've seen similar functions in other scripting languages, ie self_url(), but haven't found one in PHP. I'm doing this so that I can change which included header/footer files for different sites that use the same basic pages.
    For example, in a URL http://cdc.aibonline.org/php/testpage.php I need to be able to see that it is cdc.aibonline.org vs www.aibonline.org.
Any help? Thanks in advance

Use $_SERVER['SERVER_NAME'] Or $_SERVER['HTTP_HOST']

Run a phpinfo() script to see other environment-related variables.

<?php
    phpinfo();
?>
