PHP version: 4.1.2
PHP Bug Type: Session related
Bug description: session variables disappear
My web host recently upgraded to PHP 4.1.2. At the same time, my user
login scripts stopped working. A session variable registered with
session_register() is not holding its information when the page reloads.
Details:
I have a file included in every page that looks like:
class UserSession
{
var $user_id = 0;
var $username = "";
var $logged_in = false;
//other stuff elided
}
session_start();
global $user_session;
if (!session_is_registered("user_session"))
{
session_register("user_session");
$user_session = new UserSession();
}
function ProcessLogin($Username, $Password)
{
global $user_session;
//username and password are checked against DB contents
//if that's all good, get user row with mysql_fetch_array()
$user_session->user_id = $row[user_id];
$user_session->username = $row[user_name];
$user_session->logged_in = true;
//cookies are set and other stuff happens
}
When a page loads immediately after the user logs in, all is well, and the
values in $user_session are all as I expect them to be. Reloading the
same page, though, causes $user_session to be set back to its default
values. Before the 4.1.2 upgrade, this worked fine.
I've stripped the code down almost to what I show above, and it still
fails, so I'm pretty sure I'm not doing anything to stomp the values later
in the page. I double-checked that on the page reload, $user_session is
still registered, and it appears to be.
The changelog at http://www.php.net/ChangeLog-4.php only goes up to
version 4.1.1, so I couldn't tell if there was any change to session
variable handling in 4.1.2.
Any thoughts? All suggestions are appreciated.
