[PHP] newbie having problem with SID
Hi,
I'm just a few weeks into learning PHP, and now wants to understand
sessions. But I've run into trouble with the very first script I've tried,
even though it's more or less copied from the PHP manual.
?php
include (html_functions.php);
$title = Anders testing SID;
$header = ;
html_begin ($title, $header);
if (!session_is_registered('count')) {
session_register('count');
$count = 1;
}
else {
$count++;
}
?
?php echo $_COOKIE[PHPSESSID]?
BR

Hello visitor, you have seen this page ?php echo $count; ? times.p
To continue, A HREF=visasida.php??php echo SID?click here/A
?php
html_end();
?
The session id isn't attached to the link in the end of the script, and
therefore $count always is '1', even after I click the link.
But the $_COOKIE[PHPSESSID] does contain a value.
I'm using PHP 4.2.2 and according to phpinfo() session.use_trans_sid is
set to '1'. What I'm missing?
Best regards,
Anders Thoresson

Your system date is way off (Dec 4th instead of Dec 16th), so I may be late
in noticing your post...
The SID constant is only set if necessary, which means if you don't (or
can't) use a session cookie.
If your server is setup to use session cookies, and the client browser
returns it, SID will be empty. In this situation even the trans_sid
mechanism would change nothing in HTML output.
Anyway your problem is most certainly not tied to that, as the session
should perfectly being set up using the session cookie. You're using
session_register in version 4.2.2, where globals are not registered by
default (check the register_global setting in php.ini). You should use the
session array ($_SESSION['count']) to handle session persistent data:
html_begin ($title, $header);
if (!array_key_exists('count', $_SESSION)) {
$_SESSION['count'] = 1;
}
else {
$_SESSION['count']++;
}
end then
?php echo $_COOKIE[PHPSESSID]?

Re: [PHP] newbie having problem with SID
You should use the session array ($_SESSION['count']) to handle session persistent data: Thanks. That solved my problem. At least for the moment. I know realize that all books and all web site-prints I have covering sessions are not using the session array, but the older way to handle sessions with session_register(),session_is_registered() and session_unregister(). There are obviously differences in how things are handled now and how they were handled then. Can someone point me to a good session tutorial based on the session array rather than the pre-PHP 4.2 (I think that's the version when this was changed)?

Yes, but I don't think there are as many differences as you think.

I would recommend the online manual for date-sensitive information: http://www.php.net/manual/en/ref.session.php Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
