Status: Feedback
Bug Type: Variables related
Operating System: win2K
PHP Version: 4.1.2
New Comment:
ok here is the simpler script, please try it and you'll see very
clearly where the bug is. It should work but logically it doesn't. That
is because php doesn't flush the variables after loading a new page
which normally it should. Instead it passess the variables with an
empty string MAGICALY.

OK, but can you strip your sample script down to only a couple of
lines. Your script is waaaaaay to long, and then the bug is likely to
be caused by programming errors.
Reopening.

This is not a support question (I KNOW WHAT I'M DOING AND I DO NOT NEED
ANY HELP FROM SUPPORT) this is a bug that happened with your php
version 4.1.2 under win2k platform
the script is just there to help you to understand where the bug is.
Just to tell you one more that this script is running perfectly under
php version 4.0.6

The variables value stay empty after logout and will remain empty
forever eventhough you try to login again with different value of
username and password
