Hi,
I am trying to get $_SESSION to work on my site. In order to learn this an dunderstand it better I have built two very simple test pages to see if i can access $_SESSION on both pages.
Page 1
[PHP]
<?php /* Created on: 03/07/2007 */
session_start() ;?>
<html>
<body>
<?php
$_SESSION['item1'] = "First session variable";
echo $_SESSION['item1'];
echo '<br /> <a href="session2. php"> click here </a>';
?>
</body>
</html>
[/PHP]
This displays the $_SESSION['item1'] correctly and the link takes you to the second page.
Page 2
[PHP]
<?php /* Created on: 03/07/2007 */
session_start() ;?>
<html>
<body>
<?php
echo 'My first variable: ' . $_SESSION['item1'];
?>
</body>
</html>
[/PHP]
This however, only displays the basic text and nothing comes out from the $_SESSION['item1'].
I am really ew to this idea and I need to understand this is order to get the site I am developing to be properly interactive.
Can anybody see what am missing with this simple example?
Cheers

If your server is running on Windows, you must set the 'session.save_p ath' in your php.ini to a place Apache has permission to use.
This is the folder PHP will use to store the session data, and if it is not set it will not be able to save the data, which causes it to regenerate the session_id every time you call the session_start() method.
Some technical information then:
OS: Windows Vista Business (sorry it's not my fault)
Webserver: IIS 7.0
PHP Version: 5.2.3
Session: Enable and the save_path = "C:\Users\user\ AppData\Local\T emp\php\session " which I do have full permission on.
Interestingly I am also having trouble with php_GD2.dll but one thing at a time I guess.
Thanks for all the help so far, I'm sure we'll get this thing sorted soon.
Cheers

Well, check your session_save_pa th() folder to see if the session files are actually there. If not, you don't have valid permissions.

Session: Enable and the save_path = "C:\Users\user\ AppData\Local\T emp\php\session " which I do have full permission on.
I would recommend moving this out of the Temp thing, to a place like, for example "C:\Inetpub\php sessions\".
It doesn't really matter whether you have access, Apache must have access to it.
Try giving users like 'System' and 'Local Service' access to it, see if that works. You can also try giving everybody access, just to see if this is really the problem.

Hi Nathj
Session: Enable and the save_path = "C:\Users\user\ AppData\Local\T emp\php\session " which I do have full permission on.
can you see session records being stored within this location ?
I am running the same config on my development laptop and had more than a few issues with the new security settings in Vista..

Hi Everyone,
First of all thanks for all your help so far. I will now attempt to answer all the questions you have asked:
1) (volectricity) Is there anything in the path specified - No, there's not. It is completely empty.
2) (Atli) Apache having access and moving it to another location: I tried moving it to a different location and changed the variable in the ini file but that didnt' make any difference. Also I do not have Apache installed anywhere, I am using IIS 7 as the webserver
3) (Purple) Session records: I'm not entirely sure what I would be looking for here but the path specified is empty. What security issues did you encouter with Vista? I am so fed up with Vista that I am happy to blame it for anything and everything.
Also I thought I should post the debug information as this may help some more:
Warning: Unknown: open(C:\Users\u ser\AppData\Loc al\Temp\php\ses sion\sess_diuuc 9l68mjcpr0tfpla phb2t3, O_RDWR) failed: Permission denied (13) in Unknown on line 0
Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_pa th is correct (C:\Users\user\ AppData\Local\T emp\php\session ) in Unknown on line 0
I think I have aswered the questions asked. Thanks for the help so far I really appreciate it.

Then change the folder to be within the path your server is.
path/to/server/phpsess
It should work.
I had exactly the same problem yesterday with IIS, win xp pro and php sessions.
I would set a value in $_SESSION['count'] on one page and then it would not appear in the next page although the session id was the same on both pages.
It turned out to be the fact that I had copied a php.ini file which had a
session.save_pa th = "c:/PHP5/sessionfolder"
entry but the actual directory was not there..... as soon as I had created the directory, everything worked as I expected.
Hope that is your answer too.

The story at the moment for my session path is that the phpInfo() displays:
C:\Users\user\A ppData\Local\Te mp\php\session
This path is present and is fuly available. The php.ini file lists a path of:
C:\inetpub\phpS ession
Again this path exists and I have full access to it.
The ini file resides in C:\program files\PHP and is the one that phpInfo states is loaded.
This is the only php.ini file I can find on my local system, and as my system is standalone it can't be pulling any from a network location.
I'm really baffled by this and it is now halting development progress - never a nice feeling.
I really appreciate all the help so far and any further thoughts or suggestions are most welcome.

Hi,
Further to my last post I have done a bit more digging and there are a few mysteries.
1) The phpInfo() reports a different file to the php.ini file, a bit of a mystery.
2) The path that phpInfo() lists I don't seem to have access to, I have tried setting this in Vista and while it says I have full permission it doesn't sem to list the special permissions as being available. However, I don't think that is the problem. I tried, via fopen and fwrite to write to a file in the directory phpInfo lists for sessions and failed, however if I try that to another directory with the same permissions it works fine.
3) I also tried chmod() on the file path in question and was told I did not have permission.
All of this suggests that I should use a different file location but how do I do that if the phpInfo() is not reading from the ini file I have?
Cheers
Nathan

Hi Purple,
Did you manage to get it working at all? I can see lots of information on the web stating that this is a problem with Vista, but there has to be a solution, doesn't there?
