Urgent: Session Problem

cosegirl

How can I save a string in the session in my php server version 4.0.6? I can not use database for the request of my client.
That is why I have to use session to store data.

Since $SESSION["str"] , $REQUEST["str"] cannot be used in php 4.0.6, $HTTP_SESSION_VARS was tried, but still not work.
It looks like the session variable never is really saved. I cannot find the session once I go to another page.

Thanks very much
😕

Code list as follows:

[code=php]

page1.php

<?
session_start();

//I got "parse error", why?
if( isset($HTTP_SESSION_VARS['id']) ){
$s = $HTTP_SESSION_VARS['id']); //error occur here
}
else{
$HTTP_SESSION_VARS['id'] = "some string";
}
echo "$HTTP_SESSION_VARS['id']"; // O.K. here

//I can retrieve my session variable "id" here.
?>

===============

page2.php

<?
session_start();

if( isset($HTTP_SESSION_VARS['id']) ){
echo "read session(id) success";
}
else{
echo "session(id) not found";
}
//Always got "not found" info.
//Why I lost my session variable after I navigated from page1.php to page2.php ?
?>
[/code]

I had a similiar problem and this was my workaround:

$gen_sid = md5(uniqid(rand(),1));
$user_sid = $gen_sid;
session_name('GSID');
session_id($user_sid);
session_start();

Then, store that value that you want in a database along with the $user_sid value so that you can pull it along the way and make sure the value is for the CURRENT session.

I obviously had troubles with the session_register() and $_SESSION[] methods - this worked pretty well. Granted, it was based on a user logging in, but oh well..

I don't know why the sessions aren't working, but I can solve your parse error!

In the code:

//I got "parse error", why?
if( isset($HTTP_SESSION_VARS['id']) ){
     $s = $HTTP_SESSION_VARS['id']); //error occur here 
}

there is an extra close parenthesis on the line where $s is assigned.

It should look like:

//I got "parse error", why?
if( isset($HTTP_SESSION_VARS['id']) ){
     $s = $HTTP_SESSION_VARS['id']; //error occur here 
}
