INPUT type = hidden means an input field, but user can see it. It is used when we need to submit some data to server, but.. we don't want visitors see it.

When

[code]
<form method="GET" action="">
[/coe]

It it submit to itself, that is all data send to the code itself. We use

if (isset($_GET['secretNumber'])) {

and

if (isset($_GET['userNumber'])) {

To see if any value is sent to the server.
