Bug description:Pointer to the session dosnt work properly
Description:
------------
What I'm actually trying to do is to create pointer to session.
Ok. Piece of cake.
STEP:1
----------------
session_start();
$a = &$_SESSION;
$a[5] = 555;
-> RUN THE SCRIPT NOW;
back to edit:
session_start();
$a = &$_SESSION;
$a[5] = 555;
print_r($_SESSION);
this echoes correctly ;)
STEP:2
-----------------
Let's try to zero-memory session data.
session_start();
$a = &$_SESSION;
$_SESSION=NULL;
$a[5] = 55;
$_SESSION['abc']=555;
print_r($_SESSION);
At this point $_SESSION contains two elements.
No wonder, right? Yea..right...
Now back to edit:
session_start();
print_r($_SESSION);
At this point session contains only ONE element?
WTF happend to the $_SESSION[5]=55; it was there before...
My first shot was to unset session data with session_unset so i repleaced
SESSION=NULL with session_unset(). This gives me the same effect.
I also took a chance with session_destroy ;) but then the SESSION table
was empty (and that makes perfecly sense).
However its hard to understand why $_SESSION table is saved partialy and
not including values setted by $_SESSION reference, and WHY THIS ONLY
HAPPEND WHEN I DO SOMETHING WITH THIS TABLE to erase it ;P
Test script:
---------------
TEST SCIRPT IS PART OF DESCRIPTION.
Expected result:
----------------
All variables setted by SESSION reference after calling session_unset() are
expected to stay in SESSION.
So:
first i make session ref: $a = &$_SESSION;
then i zero-memory session by session_unset();
then i set something to session by ref. $a[5]=55;
and i expected this to stay in session.
Actual result:
--------------
If i use session_unset() or nullarize session by $_SESSION=NULL and then
set variables by session reference...The variables set by session reference
are gone after script ends.
