Are superglobal variables of PHP, where it is available in all Scopes of the script
$_SESSION is an array that stores all user session information, lasts by default 14 minutes all information in variable.
$_POST is an array that stores all the POST type parameters of the request.
$_GET is an array that stores all the GET type parameters of the request
All are a 'superglobal', or automatic global variable. This means that it is available in all scopes by the script. No need to make global $variable; to access it within a function or method.
