register_globals boolean 
Tells whether or not to register the EGPCS (Environment, GET, POST,
Cookie, Server) variables as global variables. For example; if
register_globals = on, the url http://www.example.com/test.php?id=3 will
produce $id. Or, $DOCUMENT_ROOT from $_SERVER['DOCUMENT_ROOT']. You may
want to turn this off if you don't want to clutter your scripts' global
scope with user data. As of PHP  4.2.0, this directive defaults to off.
It's preferred to go through PHP Predefined Variables instead, such as
the superglobals: $_ENV, $_GET, $_POST, $_COOKIE, and $_SERVER. Please
read the security chapter on Using register_globals for related
information. 
Please note that register_globals cannot be set at runtime (ini_set()).
Although, you can use .htaccess if your host allows it as described
above. An example .htaccess entry: php_flag register_globals on.
