Is it possible to lose Session values?

[TomatoLover]

I am having a problem with SESSION.
I thought that once I created a session variable, I can use it as long as session is alive.

But, when I reached 5th page, all session values are gone.
I tried to print out the values, using echo, but nothing was printed out.

On the 5th page, I call $_GET in order to get a passed value from the previous page. Is this the problem?

make sure you have session_start() at the top of each file you wish to have the session alive.

Sessions will only "die" if you use session destroy or close the window, in ways sessions is a more secure version of cookies, so hope that helps.
