[sniper@php.net]

ID: 25551
Updated by: [email]sniper@php.net[/email]
Reported By: brett at realestate-school dot com
-Status: Open
+Status: Bogus
Bug Type: Session related
Operating System: Linux - Red Hat
PHP Version: 4.3.1
New Comment:

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP --
the problem might already be fixed. Please download a new
PHP version from [url]http://www.php.net/downloads.php[/url]

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

We're already at 4.3.3 in which many session bugs have been fixed
(compared to 4.2.3).

Description:
------------
Problem: You have a main window that manipulates and diplays data from
a $_SESSION array. You cannot open a popup window, then manipulate your
sessions in the main window, then reload your popup window without
corrupting your session.

At first glance, it seems to work right, but once you start testing,
you realize that it just doesn't work. Sometimes you get the correct
data, usually you don't. I'm using version 4.2.3 (yes i
know...upgrade), but I originally saw this reported as a bug in an
earlier PHP version and the PHP team said it wasn't a bug, not because
they tested it, but because they said it was impossible for it to
happen due to the way PHP is written because PHP serializes all session
requests, locks the sessions..blah, blah, blah. I can therefore, only
assume that the bug still exists in later versions as it is present in
version 4.2.3 and I've found no reports of it being fixed or even
acknowledged as a bug. I found at least one other person on
phpbuilder.com who had the same problem and finally solved it by giving
up on sessions and passing his data in a query string.

It's not our problem if you can't upgrade.
And sessions work just fine. You're either doing something
wrong or there was some bug fixed, related/not related to sessions.

After 2 weeks of searching, I have not found one report of this being
fixed in any PHP version. I am not able to upgrade my version of PHP to
test this on newer versions. Please do not close this issue until
someone has.
