PHP Bug Type: Session related
Bug description: Referencing Global Variables
Description:
------------
A global variable which references a session variable
inside a class loses its global scope.
Reproduce code:
---------------
<?php
session_start();
class test {
function test() {
global $b;
if (!isset($_SESSION['a'])) {
$_SESSION['a'] = 0;
}
$b =& $_SESSION['a'];
}
}
$test = new test;
$b++;
echo $b;
echo '<br><br>';
echo '<a href="' . basename($_SERVER['PHP_SELF']) . ((defined('SID') &&
strlen(SID) > 0) ? '?' . SID : '') . '">reload</a>';
?>
Expected result:
----------------
The counter shown should be incremented on each page
reload.
Actual result:
--------------
The counter does not get incremented and stays at 1.
Changing the following line:
$b =& $_SESSION['a'];
to:
$GLOBALS['b'] =& $_SESSION['a'];
produces the expected result.
