Accessing global variables in a separate PHP script?

Question

I'm trying to import some variables from a PHP script. It seems simple but I cannot get it to work.

The script contains some global variables like that:

$server_hostname = "localhost";
$server_database = "kimai";
$server_username = "root";
$server_password = "";
$server_conn     = "mysql";
$server_type     = "";
$server_prefix   = "kimai_";
$language        = "en";
$password_salt   = "7c0wFhYHHnK5hJsNI9Coo";

Then in my script, I would like to access these variables, so I've done:

require_once 'includes/autoconf.php';   
var_dump($server_hostname);

But this just outputs NULL. I've also tried:

require_once 'includes/autoconf.php';

global $server_hostname;    
var_dump($server_hostname);

but still not working.

I've added some echo statements in the "autoconf.php" file so I know that it's being loaded.

Any idea how I could access these variables?

You have to define the variable as global first:

global $server_hostname;
$server_hostname = "localhost";
