Superglobals — Superglobals are built-in variables that are always available in all scopes
Several predefined variables in PHP are "superglobals", which means they are available in all scopes throughout a script. There is no need to do global $variable; to access them within functions or methods.
These superglobal variables are:

$GLOBALS
$_SERVER
$_GET
$_POST
$_FILES
$_COOKIE
$_SESSION
$_REQUEST
$_ENV

$GLOBALS
$GLOBALS — References all variables available in global scope
An associative array containing references to all variables which are currently defined in the global scope of the script. The variable names are the keys of the array.
