PHP Server Name from Command Line

Question

Is there a way to detect the name of the server running a PHP script from the command line?

There are numerous ways to do this for PHP accessed via HTTP. But there does not appear to be a way to do this for CLI.

For example:

$_SERVER['SERVER_NAME']  

is not available from the command line.
