Description:
------------
I read in the manual that the use of session_register() is deprecated and that session variables should now be registered simply by creating, and assigning a value to, a member of the $_SESSION array.

Well, try as I may, I just cannot register session variables without using session_register(). If, however, I use session_register() before assigning a value to the new session variable via $_SESSION['x'], everything works fine.

Reproduce code:
---------------
// PAGE A (start.php):

<?php
session_start();
$_SESSION['test'] = 'my test';
?>

/*******/

// PAGE B (test.php, called after start.php, obviously):

<?php
session_start();
print $_SESSION['test'];
?>

Expected result:
----------------
OUTPUT TO SCREEN:

my test

Actual result:
--------------
OUTPUT TO SCREEN:

Notice: Undefined index: test in D:\htdocs\Test\session\test.php on line 3

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Works fine, if start.php which intializes the session variable is always started before test.php, which uses it.

First of all, thanks a lot for taking time to reply to my post so quickly.

Now, while I have not taken any offence whatsoever and can only imagine how busy you must be, I am *not* a newby and have *always* called start.php before test.php. The session variable ($_SESSION['test']) simply will *not* be registered unless I *reload* start.php (i.e. load it twice). On the start.php page I have included a
link to test.php, so that the second page is only called after the first, i.e. the session variable was *supposed* to have been initialized.

Perhaps this is a bug only affecting PHP under Windows?

Works fine for me under Windows. (using Apache 2.0.47 and a working script). Please don't reopen this, there is no bug here.

Well, I belive you and I have had many problems with sessions too.
some are saved some are saved but empty and some are never saved.
sessions do what they want and when they want it.
I'm also not a newby and I write critics about programms.
I'm sure that there is buffer over run problem in the sessions code and it will tack a while till someone would open his eyes.
In the meanwhile do what all others do.
1) use mysql to save your sessions.
2) create and save them as files yourself.
for this you already find a lot of solutions on net.

and now comes the automaticaly copy and paste answer :)
