$_COOKIE -- $HTTP_COOKIE_VARS [deprecated] — HTTP Cookies
Description
An associative array of variables passed to the current script
via HTTP Cookies.
$HTTP_COOKIE_VARS contains the same initial
information, but is not a superglobal.
(Note that $HTTP_COOKIE_VARS and $_COOKIE
are different variables and that PHP handles them as such)

Introduced $_COOKIE that deprecated
$HTTP_COOKIE_VARS.

Hello Hannes!
Notes
Note: This is a 'superglobal', or
automatic global, variable. This simply means that it is available in
all scopes throughout a script. There is no need to do
global $variable; to access it within functions or methods.
