GET and POST are just the names of two methods of sending an HTTP
request, not to be confused with the PHP variables of the same name.
The PHP variable $_GET makes available name=value pairs passed in the
query part of the request-URL (even if the actual method is POST), and
$_POST makes available name=value pairs passed in the body of the
request. $_SERVER, on the other hand, makes available some but not all
of the headers of the request.
