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.
