[PHP] Multiple sessions open at same time, is it possible?
Hello, I'm quite new to sessions, an am trying to program a script which needs two sessions ... I have a members area which uses 1 session, and when you click on disconnect it closes the session and the user returns to the login page. I also am programming a shopping cart so members can choose what they would like to download that also uses a session. All worked fine untill I realised that because they both use the same session, when I disconnect from the members area it also obviously deletes all elements from the download cart. I would there for need to have two seperate sessions one for the cart, and one for the members area. And sometimes I will need to have them both open. Is this possible ? I've searched google but not found anything interesting, except session_name, but I still don't know how to open two sessions or close one session but not the other, or open a variable in a specific session ...

Just use one session. Put the data for each session into a separate
array...
$_SESSION['members'] = array('lots', 'of', 'data');
$_SESSION['cart'] = array('lots', 'of', 'money-making', 'crap');
To disconnect the user from one or other simply unset that variable...
unset($_SESSION['members']);
unset($_SESSION['cart']);

Thankyou, instead of unsetting the whole session, I just unset de
password, so the user has to login again and now it does not reset the
cart anymore.
However, is there a way to limit the session stay alive time for just
one variable ?
If for example, if a user has not done anything in his members area for
more than 30 minutes I would like to be able to reset his password, but
I do not want to reset the cart. Do I have to program this seperatly in
PHP (IE set a session varibale $_SESSION['last_time'] = time(); and on
each page loads :
if ( time() - $_SESSION[last_time] 1800) {
$_SESSION['password'] = array();
else {
$_SESSION['last_time'] = time()
}
...
Or is there a better way to do this?
Thanks again :)

There is no built-in mechanism for this so you need to implement your
own as above. Personally I would store it as an expiry time rather
than the current time, but whatever floats ya boat.

Sorry, I only know how to use current time, just for my personal

can't work out how you would do this without using the current time...

It's really not rocket science...
if ($_SESSION['expiry'] time())
{
$_SESSION['password'] = array();
}
else
{
// Password expires in 30 minutes
$_SESSION['expiry'] = time() + 1800;
}
Just curious... why are you setting the password to an empty array?
You'd probably be better off unset'ing it so you can use isset to
check for it.

Oh right ! :)
Yes you're right about the array, I used it by mistake, as to reset a
value in $_SESSION[cart] , ie : $_SESSION['cart']['item_number'] I had
to do $_SESSION['cart']['item_number'] = array(); as unset would anly
work for unsetting the whole cart and not just one item, but yes it
would be best to use unset for $_SESSION['password'] !

[PHP] Multiple sessions
Hi.
Is there a way to have multiple sessions open in one browser
(specifically, Firefox or Safari)? For example, IE does not transfer
session data from one window to another, however, Firefox does. So,
if one user opens a session and then his/her friend wants to open a
different session of that same program on the same computer, (s)he is
not able to without overwriting the first session data.
I have thought of one solution, but have yet to test it. Upon the
first user logging in, I could assign them as session ID (along with
the one that PHP creates). I could then verify that ID is being used
on each page. For the second user, I could create a different one and
do the same as the first.
? // User 1
$_SESSION[my_special_id] = abcd; // created upon logging in
if ($_SESSION[is_logged_in]
$_SESSION[my_special_id] == $_GET[my_special_id]) {
// do stuff
}
?
? // User 2 in a different window of Firefox
$_SESSION[my_special_id] = efgh; // created upon logging in
if ($_SESSION[is_logged_in]
$_SESSION[my_special_id] == $_GET[my_special_id]) {
// do stuff
}
?
Notice that they both share the same is_logged_in variable, but a
different my_special_id variable. Actually, I just noticed
something. If User 1 logs out and kills is_logged_in, that would
also kill it for User 2.
I don't know. I've confused myself now. Any suggestions? Common
practices?
Thanks in advance,
~Philip

Not strictly true. It's actually based on instances. Firefox differs
from IE because if you start a new Firefox instance it joins the
existing instance if it exists. IE does not do this. To get the 'shared'
session in IE open a new window from the existing window instead of
starting a new copy of IE.

I'm confused as to why you need a solution to this 'problem'. How likely
is it that you'll have 2 users trying to access your site on the same
machine at the same time? If it is likely (although I don't see how)
then you need to design your session data as an array keyed on the
username, but that would be very insecure.
In short are you trying to solve a perceived problem when no such
problem actually exists? Think about it for a while before jumping to
working around it.

[PHP] multiple sessions
Hi, all -- I am trying to integrate phpbb into our web site and do so such that we set the login info before getting into the forum. We have a user 'x' who has a numeric user_id 'y' in the phpbb system that we'll need to set. We store that user_id in our system for other uses as well. Our cookie is simply named PHPSESSID and we usually see the session data by looking in $_SESSION. The phpbb cookie is named phpbb2mysql_data and has other good stuff in it. When I am in the phpbb code I want to be able to look at the PHPSESSID session data so that I can extract the user_id and pre-set it and then go on to create the phpbb cookie and so on. When I get there, though, I find that $_SESSION is empty. How do I look at the data stored in another cookie or session -- if I'm even using the terminology correctly?
