Description:
------------
hello... i'm having problem here... example, i got 2 files... 1st file contains (test.php)
<?php session_start();
$_SESSION['xxx']="hello";
$xxx="world";
echo $xxx;
echo "<br>".$_SESSION['xxx'];
?>
then the 2nd file (test2.php)
<?php
session_start();
$xxx="world";
echo $xxx;
echo "<br>".$_SESSION['xxx'];
?>
if i'm goin to use PHP 4 for those files (say access test.php 1st, then next test2.php)... test.php would output "world hello"... and test2.php would output "world hello"... the problem rises when i used PHP 5... 1st file would output "world hello" but the 2nd file's output is "world world"... apparently, the $_SESSION['xxx'] value changed whenever $xxx value changes... is this some kind of bug under variable scoping?

In PHP 4.2.0, the 'register_globals' setting default changed to
'off'. See http://www.php.net/release_4_2_0.php for more info.
We are sorry about the inconvenience, but this change was a necessary
part of our efforts to make PHP scripting more secure and portable.
