Reported By: [EMAIL PROTECTED]
Status: Bogus
Bug Type: Session related
Operating System: linux 2.2.18 - glibc 2.1.3
PHP Version: 4.1.0
New Comment:
Oops,
here is the explanation:
the function 'session_register()' 'registers' a variabele to a session. In other
words, when the script ends, the value of this variabele is stored with the session.
On the first run $PIPPO is empty (of course), and it is set to 'ONE'.
At the end of the script, the value is stored in the session file.
At the second run, (PIPPO is still registered to the session, so session_register has
no effect), empty($PIPPO) evalutes to TRUE again, because the value is in
$_SESSION['PIPPO'], and thus PIPPO is set to 'ONE' again.
At the end of the script, the value of $PIPPO ('ONE') is saved to the session again.
You can see more of this behavior, if you set error_reporting(E_ALL) to on in the
script.
Hope this explained it,
regards,
Derick

Hello,
let me explain this,
------------------------------------------------------------------------

There is something I don't understand.
I've updated to v4.1.0 and noticed that the recommended
configuration defaults register_globals to *Off*. I
understand the security reasons behind this choice. I've
tried to run one of my projects with the new interpreter
and the recommended settings (register_globals=Off). After
resolving a plenty of warnings, I noticed that things were
not working as I expected.
This is a sample code:
<?
session_register('PIPPO');
if (empty($PIPPO)) {
$PIPPO = "ONE";
} else {
$PIPPO = "TWO";
}
$sidfile = "/tmp/sess_" . $_COOKIE['PHPSESSID'];
echo "Session file $sidfile contains: <pre>";
readfile($sidfile);
echo "</pre>";
echo "The value is: $PIPPO<br>";
?>
When I run and reload the script I get:
Session file /tmp/sess_87...blahblah...3e contains:
PIPPO|s:3:"ONE";maxrating|N;
The value is: ONE
Why the first run sets the session variable to "ONE" and
the second run can't get it's value? In the latter case I
guess the answer is: "because you have to access it through
$HTTP_SESSION_VARS", but ... shouldn't it had to be the
same in the former case?
