global and $_SESSION variables with the same name are the same

I got a piece of code:

$_SESSION['cms_lang'] = 2;
global $cms_lang;
$cms_lang[1] = 'en';

Error:

Cannot use a scalar value as an array

Problem is that, I really don't know why server sees my global variable as the same as $_SESSION variable. I used this piece of code a couple of times and never had problem with that. I guess it must depends of settings on server. Can anyone know how to force server to not take global and session variables with the same name as the same?

You may read up on the PHP configuration setting register_globals which enables this behavior.

Also, read about why you should disable it (and generally, upgrade your PHP version!)
