getenv on arrays

When I do a getenv on an array like HTTP_COOKIE_VARS I get nothing back.
How can I make sure I am getting the right cookie value back if I can't use getenv? Or maybe I'm just missing something entirely.

HTTP_COOKIE_VARS is not an environmental variable. getenv() will not get you anything when used with it.

You can use each() to get a list of keys from the array, which is the names of the variables stored in the cookie.
