session problem (HELP!!!)

trinityphp

I am having problems with sessions...the code i am trying out is

<?php
session_start();

$_SESSION["sess_var"] = "Hello World";

echo 'the content is '. $HTTP_SESSION_VARS['sess_var'];
?>
<a href="page2.php">Next Page</a>

the code on page2.php is

<?php
echo 'the content is'.$HTTP_SESSION_VARS['sess_var'];
?>

page2 does not diaplay the value of sess_var.
I am using php Version 4.3.1
is there some configuration to be done in the php.ini file?
PLEASE HELP....

All you need to do is put the session_start(); command at the top of the second page. You need to call that command to initialize the session for that page. Here is what it says in the PHP manual:

Description
bool session_start ( void)

session_start() creates a session (or resumes the current one based on the session id being passed via a GET variable or a cookie).

If you want to use a named session, you must call session_name() before calling session_start().

This function always returns TRUE.

Note: If you are using cookie-based sessions, you must call session_start() before anything is output to the browser.

I tried it on your exampleand it works fine.

I did mention the session_start() in my original script...made a mistake while writing my previous message. I still dont see the variable value.....!!!
the actual code is
<?php
session_start();
echo 'the content is'.$HTTP_SESSION_VARS['sess_var'];
?>

what is the problem? please help.

Thanks

Not exactly sure what the problem would be because it works fine for me. PHP 4.3 and above session support is on by default. I will keep looking, but nothing is jumping out at me.

is there some change to be done to the session.save_path setting in the php.ini file??

current the setting in php.ini file is

session.save_path /tmp /tmp

may i know what the value is for this field in your php.ini file?

thanks

I am running apache on windows so i had to change the setting for the session.save_path field in the php.ini file.

Now the variables are getting registered.
