I'm quite new to sessions, an am trying to program a script which

I have a members area which uses 1 session, and when you click on

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']);
KISS.

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
interest, how would you use expiry time ? I've looked around a bit and
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.

Hi all,
I've tried googling around to find some blogs with decent information
on whether Zend Eclipse is mature enough to make the jump over from
5.5.x just yet.
Admittedly, I've dropped Zend Studio as of late and been writing all
of my code in TextMate -- but at the end of the day when a project is
complex enough, Zend Studio is much more powerful than TextMate with
all of its features and remote debugging capabilities.
Anyhow, I'm curious if it's worth it to check out Zend Eclipse yet.
We're a team of about 5-6 developers and I've been getting asked by a
few colleagues if I've tried it out yet since I'm usually the one to
try out the newer technologies.
I'd love to hear some feedback.
Thanks!
/sf
I've recently switched. On my machine (which hasn't been updated for a
long time...) Eclipse runs a lot slower. I only have 1 GB of RAM. Zend
Studio has been running faster for me after I turned off the SVN
integration. I just use the CLI for SVN anyway.
Sometimes in Eclipse it'll slow down so much that I have to slow down my
typing. Mostly that's in CSS files. I don't know if it's Eclipse in
general, but Shift+Tab rarely works, and it drives me nuts. I've tried
to mess with the key bindings to no avail. Debugging is a lot slower in
Eclipse. Some of the default key bindings in Zend Studio are different
in Zend Eclipse as well, but that was somewhat expected and hasn't
bothered me too much.
I've been using the official Zend Eclipse now since the day it came out.
Next week I'm going to switch back to regular Zend Studio. It was
nicer on the RAM and for the most part "Just Worked"(TM).
That's my experience. I'd be interested to hear other people's experiences.

-Stut
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'] !

Eh? What's in $_SESSION['cart']['item_number']? You might want to
consider one of the following depending on what's in that array
element...
unset($_SESSION['cart']['item_number']);
unset($_SESSION['cart'][array_search($itemtoremove,
$_SESSION['cart'])]);
unset($_SESSION['cart']['item_number'][array_search($itemtoremove,
$_SESSION['cart']['item_number'])]);
At the very least it would be better to use null rather than array(),
but actually removing the item from the array would be my
recommendation.

Sorry I went back to where I read that I should use =array(); and I miss
read an instruction which was : http://fr3.php.net/unset
|
|Quote from http://fr.php.net/session_unset
"Do NOT unset the whole $_SESSION with unset($_SESSION) as this will
disable the registering of session variables through the $_SESSION
superglobal."
So basically don't do:
unset($_SESSION)
Instead do:
$_SESSION = array();|
So no need for setting my session variables to array()...

have you considered installing a local copy of php (and suitable webserver)
so you can test it there?
I'd also suggest using a revision control system (subversion or git) and
have pre-commit hooks to check the syntax.
It's a bit of work to set up but once it's done you'll notice a
difference - just knowing how often you're changing things can be
surprising.

It's possible that there is an .htaccess file in phpMyAdmin that has
Magic Quotes on that is messing you up...
Other than that, it's specific to phpMyAdmin, so maybe ask those guys
what they did...
