Is there any way by which I can add keys to superglobals in php without defining the corresponding values to those key?

For example:

$_SESSION['key']='set';//key` automatically gets defined.

But I want to do something like this

add_key($_SESSION,'key')//key is added to $_SESSION array.

Is it possible?
