Use of $_SESSION is preferred, as of PHP 4.1.0
If your script uses session_register(), it will not work in environments where the PHP directive register_globals is disabled.
As of PHP 4.2.0, the default value for the PHP directive register_globals is off . . . The PHP community discourages developers from relying on this directive, and encourages the use of other means, such as the superglobals.
