1. Environment variables: $_ENV
These variables are imported into PHP's global namespace from the environment
under which the PHP parser is running. Many are provided by the shell under
which PHP is running and different systems are likely running different kinds of
shells.
This is a 'superglobal', or automatic global, variable. This simply means that it is
available in all scopes throughout a script. You don't need to do a global $_ENV; to
access it within functions or methods, as you do with $HTTP_ENV_VARS.
Ex: print_r($_ENV);
