Question

I have two pages. On one page I am adding an array to $_SESSION. On a second page, I am reading the array (successfully), and then unset that array from $_SESSION.

What happens however is that the second page shows different values than what the first page stored in the session – and that leads me to think that the first page is called again and again, but how can that be if I am on a session and not reloading the page again myself?

What am I doing wrong? Thanks

EDIT: Forgot to mention that the second script is requested by a flash file on the website. The flash file has the session ID as one of its parameters and then sends it to the second script to load the right session (the session_id($_REQUEST['token']); part).

Page 1:

$_SESSION['HEADER_MODEL'] = getModelForHeaderVideo();
/*
    [HEADER_MODEL] => Array
        (
            Yes these are just random numbers (for testing)
            [modID] => 303768959
            [modUsername] => 347073152
        )
*/

Page 2:

<?php
        session_id($_REQUEST['token']);
        session_start();

        header('Content-Type: text/html; charset=utf-8');

        if (!isset($_SESSION['HEADER_MODEL']['modID']) || (trim($_SESSION['HEADER_MODEL']['modID']) == '')) {
                echo "modID=0";
        } else {
                echo "&modID={$_SESSION['HEADER_MODEL']['modID']}&modUsername={$_SESSION['HEADER_MODEL']['modUsername']}";
                unset($_SESSION['HEADER_MODEL']);
        }
?>

Please Refer to the PHP documentation

Note: When using session cookies, specifying an id for session_id() will always send a new cookie when session_start() is called, regardless if the current session id is identical to the one being set.

PHP session array keeps changing because that is what your code instruct it to do
