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

You're not missing anything. It sounds like a problem with a local installation. Is this a local test?

volectricity,
Yep, it's a local test. I have checked my browsers and cookies are enabled, though I was led to beleive that $_SESSION was completely server side and so did not need cookies. What else could it be? Is there something in the ini file that I need?

Well, it'd actually be more a filesystem issue.
Here, put this on both pages and tell me if you get the same result:

Just a shot in the dark. It happened to me once.
If you first page lets say you call it session.php is called from http://example.com/session.php
and your second page is
http://www.example.com/session2.php
The session is not carried over. see the www and the non www. Make sure both pages are www or both non www.

That sounds like it could cause problems. Actually, it's more of issue of the fact that you have the http:// included when you do it.
However, in this post, the sample code uses a relative link.

Have you tried to run ,
[PHP]phpinfo();[/PHP]
and double check your settings.

I have looked at the phpinfo() results and can see that sessions are enabled and everything there looks like the sample you gave, except hash_bits_per_c haracter = 5 on my installation, I don't know if that has anything to do with it?

The session id is the same on both pages.
As for the www I am building this at present on localhost. I have tried using complete and relative paths and this does not affect the current behaviour. I will however, bear that in mind when I come to the production stage of the project.

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.

Also, I'm reading mixed things about sessions. php.net says you can
