if that is all the php there is on the page, it won't work because you're not sending the value of the variable across pages.

If that's an excerpt, my guess is $view isn't being set.

It is also possible that $view is being rendered as part of the (x)HTML so it won't be seen unless you do "View Source".

Hi

now, that is all my code, i save it in test.php. Yes you right i fail to sending value. I don't undertand how to set $view. If i set $view = "hallo" and i print with echo $value, it will show hallo.

Right. So to send the variable, you can either pass it through the URL, or you can set a SESSION variable, or a COOKIE. If you look at PHP.net for SESSIONS and COOKIES or google on using GET variables, you'll find a plethora of information.
