My name is Dennis, currently im doing my final year project for a system called " Records Management System" I'm using xampplite localhost phpmyadmin as my database SQL server.
i face a problem in my system that shown a message:

"Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0"

How can i solve this problem or disable this message ? Urgent !
Hope to get ur reply soon. Thank you very much :)

Thank you so much mahavir, actually i'm just a beginner to PHP. so need to ask u again.
This is my coding:
<?php
session_start();
$Sname = $_SESSION[Sname];
require_once('./includes/db.php');
?>
So u mean using session_register(); instead of session_start(); ?

I have searched and I think in PHP 4.2.0 and onwards, register_globals directive defaults to off so your code should work.
So don't change your code. If you let me see your code, may be i help you.

You could also enable your 'register_globals' in your 'php.ini' file at your server.

Can you show me the step how to enable my register_globals ? really embarrassing to show my code here, the coding is quite messy...
My code is shown below:

staff.php

<?php
    session_start();
    require_once('./includes/db.php');
$query  = "select * from staff where Sname='$Sname'";
$result = mysql_query($query) or die('Error, query failed '. mysql_error());
$row=mysql_fetch_array($result);

    ?>

Sorry to tell you, your code works fine in my system.
I am using php5

You can change 'register_globals' in your server.

Open the server control
In 'configuration' TAB open PHP->php.ini
search for word 'register_globals'
You can change the value

register_globals = off
register_globals = on

After change anything on php.ini, you have to restart the server.
