Difference between PHP Version 4.3.11 and PHP Version 4.3.1

On Session Variables

[Francis]

Our host currently migrated to PHP Version 4.3.11.

Is there a difference in which PHP Version 4.3.11 handles session variables?

Because prior to migration our PHP scripts worked without a hitch. For example, consider the script below:

?php
/* Determine whether member is logged in or not and display corresponding graphic message */
if (!isset($_SESSION['member_name'])) {?>
<IMG SRC="<?php $_SERVER['DOCUMENT_ROOT']?>/images_submenu/status_guest.jpg" WIDTH=105 HEIGHT=23 ALT="">
<?php } else {?>
<IMG SRC="<?php $_SERVER['DOCUMENT_ROOT']?>/images_submenu/status_logged.jpg" WIDTH=105 HEIGHT=23 ALT="">
<?php }?>

The script is suppose to display a LOGGED-IN status whenever a user has correctly logged-in on the site validated by the (!isset($_SESSION['member_name'])).

But now, after processing the validation through a form on the index page (reads the MySQL DB and checks), the variables seems to be lost when it goes back to the index page. Validation is done through a separate script file.

Local testing works perfectly. We are using the following specs:

1. Windows XP Pro
2. Apache 2.0.48
3. PHP Version 4.3.1
4. MySQL 3.23.55

Any ideas? Thanks again.

This code:

<?php $_SERVER['DOCUMENT_ROOT']?>

does absolutely nothing. Which is just as well because the DOCUMENT_ROOT isn't relevant for the browser - only to the file system.

You should check phpinfo() to see if the settings for sessions, or register_globals, etc have changed.

all that code should be is

if (!isset($_SESSION['member_name'])) {?>
<IMG SRC="/images_submenu/status_guest.jpg" WIDTH=105 HEIGHT=23 ALT="">
<?php } else {?>
<IMG SRC="/images_submenu/status_logged.jpg" WIDTH=105 HEIGHT=23 ALT="">
<?php }?>

the images will resolve as long as they are root relative, so start with a / and have the absolute path from there.

>> the variables seems to be lost

which variables? the session?

also what are the differences between your local and remote setups. I understand the 4.3.1 and 4.3.11 diff but are they both windows, are they both confgured the same?

Hi everybody.

Thanks for the reply. I printed out my PHP 4.3.1 configuration as well as our hosts PHP 4.3.11 configuration but there was not much difference.

However, I tried using another PC and checked again, the whole problem has been resolved. Meaning, the log-in display is working.

I tried clearing my browser's cache and deleting all temporary internet files. That solved the problem.

Now, my question is, is there a header command that would automatically do this for me? Or a header command that will automatically load the server's content without basing the site on the content of the local PC?

Hope this makes sense. Thanks again and more power.

hehe, you don't know how many times each of wish there was something we could use from the server-side to fix browser issues. Sorry, Francis, we are at the mercy of the browser.
