Описание
An associative array of variables passed to the current script
via the HTTP GET method.
$HTTP_GET_VARS contains the same initial
information, but is not a superglobal.
(Note that $HTTP_GET_VARS and $_GET
are different variables and that PHP handles them as such)

Замечание: 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.
