[SOLVED] HTTP_SESSION_VARS doesn't return a value

[Dumps]

I have used $_SESSION successfully in the past, but the server I have to use for a project is using PHP 4.0.1 so I have to use HTTP_SESSION_VARS instead.

 

I can't seem to get it to return a value for some reason. I've checked and register_globals is on.

 

If I assign a value to a HTTP_SESSION_VARS variable I can return it on the same page ok:

<?php
session_start();
$HTTP_SESSION_VARS['tester'] = "This is a test";
print "{$HTTP_SESSION_VARS['tester']}";
?>

 

outputs: This is a test

 

However, obviously this is not much use and I want to be able to use the variable on other pages - ie use it globally. If I try this on another page:

 

<?php
session_start();
print "{$HTTP_SESSION_VARS['tester']}";
?>

 

nothing is returned.

 

Essentially I've used it in the same way as I would $_SESSION without success.

 

Clearly I'm missing something - I've checked the docs and as far as I can make out this should work.

 

Can anyone point me in the right direction please?

Hi

 

if im not mistaken, http_session_vars is not superglobal, so you have to use the global directive to access if:

 

<?php
session_start();
global $HTTP_SESSION_VARS;
print_r ($HTTP_SESSION_VARS);
?>

 

cheers,

use $_SESSION['tester'] instead?

Also, keep in mind sessions last for the subdomain.

http://site.com will have a different sessionID than

http://www.site.com

Hmmm had tried that so have tried again:

 

session_start();
global $HTTP_SESSION_VARS;
$HTTP_SESSION_VARS['tester'] = 'This is a test';

 

and

 

session_start();
global $HTTP_SESSION_VARS;
print_r ($HTTP_SESSION_VARS);

 

but still nothing. I just get Array() for the empty array.

 

Cheers anyway but any other ideas?

[Jessica]

Use $_SESSION.

[Dumps]

I didn't think you could use $_SESSION on anything earlier than PHP 4.1.0. and I have to use 4.0.1 (this is beyond my control).

 

Still stuck - I'm sure there must be a simple explanation / something basic I'm missing....?

[jitesh]

check in php.ini "register_long_arrays" is On

 

+

 

Restart Webserver

According to the documentation that directive only became available with version 5 and I'm unfortunately having to use 4.0.1.

 

Thanks anyway but no joy there. Hmmmm, this is a knotty one.....

[xyn]

Hm I don't know if this is the problem. but you coudl check if

globals are turned off. if so you will need to turn them on!

 

ini_set('register_globals', 1);

[ToonMariner]

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

 

leave globals off....

 

why not just upgrade the php engine?

 

If I were paying for hosting with php 4.0.1 on I'd be very upset! If I had control over teh box I'd install later version myself.

 

[xyn]

Well i suggest trying it with globals ON.

if it works then globals is your problem

if no change, turn them off and we can think

of another way!

[Dumps]

register_globals is on so I've tried turning them off:

 

<?php
session_start();
ini_set('register_globals', 0);
global $HTTP_SESSION_VARS;
$HTTP_SESSION_VARS['tester'] = 'This is a test';
?>

 

and it makes no difference - other pages just return an empty array. I thought globals should be on anyway.

 

Yes, upgrading would be the simplest option but its a work box (I certainly wouldn't pay for 4.0.1) and IT are reluctant to upgrade for some reason. I am working on them, but in the meantime.......

 

This is a strange one as I've got HTTP_POST_VARS working fine, its just the session array thats the problem.

[xyn]

oh i know try...

{$_SERVER['HTTP_SESSION_VARS']['tester']}

[xyn]

Or. failing then print_r($_SERVER['HTTP_SESSION_VARS']);

[Dumps]

Nope no joy with that - it just returns an empty array.

 

This is somewhat perplexing.

???

[Dumps]

At last I've solved this, and it was, as expected, quite simple.

 

<?php
session_start();
$test = "at last this works!!!";
session_register('test');
?>

 

and to use the session variable $test

 

<?php
session_start();
print_r($HTTP_SESSION_VARS['test']);
?>
