Bug description: Iterate over $_SESSION won't allow to unset its fields
Description:
------------
The following session is stored in my temp directory:
old_var2|s:4:"foo2";
I try to iterate over the $_SESSION var (using foreach) to unset some
session keys, in particular those who start with "old_" (see the attached
code). But I can't.
Besides, if after this iteration I try to modify the $_SESSION var nothing
happens.
I'm using IIS 5.1 (blame my boss).
Reproduce code:
---------------
session_start();
$prefix = 'old_';
foreach ($_SESSION as $key => $value) {
if (substr($key, 0, 4) == $prefix) {
unset($_SESSION[$key]);
}
}
$_SESSION['var1'] = 'foo';
Expected result:
----------------
This change in the session file:
var1|s:3:"foo";
Actual result:
--------------
old_var2|s:4:"foo2";
