Note: Because this is a language construct and not a function, it cannot be called using variable functions.

Warning

Note: register_globals: important note

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.
