Sessions x variables

[yankleber]

Hello my friends,

I am experiencing some weird problem, that I believe is in my PHP interpreter, but I cant figure it out by myself.
I am dealing with a simple session variable issue...
I have two scripts, in the first I create a variable and register that:

<?php

session_start();
session_destroy();

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

header("Location: increase.php");
?>

In the second script, I just catch the variable and increase it:

<?php

session_start();
$test = $_SESSION["test"];
$test++;
print $test;

?>

Simple, uh? Well, anytime I press F5 the $test variable should be increased by 1, but... nothing happens!

I can register and pass variables but not update them.

The weirdest of the whole thing is that it not works on my development environment (I am running PHP 4.3.4 under Apache, Windows 98) , but works on the server where is the website of my customer (PHP 4.3.3, Apache, Linux).

Can anyone help me to fix that?

Thanks a lot!

page.php

<?
session_start();
$username = "Sam";
$_SESSION['[e-mail]'] = $username;

echo "<a href="page2.php">Click</a>";

?>

page2.php

<?
session_start();
$username = $_SESSION['[e-mail]'];
if($username != 'Sam'){
echo "Your not Sam!";
} else {
echo "Hello Sam.";
}
?>

Do not use [man]session_register[/man]. It depends on [man]register_globals[/man], which is bad, and now disabled by default.

In both of your scripts, do "$SESSION['test'] = $test" after $test contains the value you want to pass to the next page. Then it'll all work. As long as you call session_start() at the beginning of each page, the contents of the $SESSION array should be preserved across pages.

Also, something tells me you shouldn't be calling session_destroy() after session_start(). I could be wrong though, as I'm not familiar with the details of what session_destroy() does; I can't think of any instance where I've needed to use it.

If I remember correctly, you have to start the session...session_start() for it to know what session to destroy...Session_destroy()

Could be wrong though

actually to destroy a session you must use

unset($_SESSION['sessionName']);

with sessionName being the sessions name of course.

Hi fellows!

I apreciate your efforts to try to help me, but I think that anybody even got closer, maybe because I couldnt express myself clearly.
Everybody seems worried the way I am creating the sessions and how to destroy them. I would like to clearify that THE PROBLEM IS NOT THERE!

The sessions are being created ok exactly the way it is.

Please, pay attention to THE REAL PROBLEM ! The problem is not the creation or destruction of the session, but the fact that the created variable cannot be updated: once they are created, they keep the same value all the time.

But, PAY ATTENTION NOW !!! In the host where my customer have his website, the scripts (exactly as they are here) works, but not in my machine.

THAT'S IT, what I need to know how to solve!!!
