Sessions

[Anon]

Hello: My problem is that I´m trying to make an aplication in PHP and I have to use sessions and save information about everyone who access the page. In the first page I have this code:
- session_register("codigo")
- $codigo = 0

And when I go to other page, when I try to get the value of that variable, it is blank. I think I make all right. In the php.ini, I have the session timeout = 0, and it means that the session´s var expires when the explorer is restarted.

Well, if you can tell me anything, write.

Thank you

You have to call $codigo=0 before you register the variable. For example :

$codigo=0;
session_register("codigo");

OK, but if I modify the variable another time, like:

$codigo = 2
.....
$codigo = 3
.....

The changes are saved or no?
