ID: 15822 Updated by: sniper@php.net Reported By: php@bradandkristin.com -Status: Duplicate +Status: Bogus Bug Type: Session related Operating System: Linux 2.2.19 PHP Version: 4.1.2 New Comment: Thank you for taking the time to report a problem with PHP. Unfortunately your version of PHP is too old -- the problem might already be fixed. Please download a new PHP version from http://www.php.net/downloads.php If you are able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". Again, thank you for your continued support of PHP.

(PHP 4.1.2 and Linux 2.2.16) Calling session_register(mySessVar) after session_start() seems to fix the problem - strange. ------------------------------------------------------------------------ [2002-03-04 13:27:21] php@bradandkristin.com I did. I also checked the changelog, but it's still not updated for 4.1.2. I also checked the session fn docs, but didn't see anything relevant in either the static documentation or the comments. Perhaps the bug is marked as closed already? I'm not sure I checked for closed bugs, but you didn't include the original bug number when telling me my entry was a duplicate, so I really have no idea what it was I missed on my first search. If it's a known bug, is it slated to be fixed? In 4.2.0? Is there a work-around? Again, my search for further information has left me dry. Any pointer to a worthwhile starting point, even just the original bug #, would be far more useful than simply assuming I never bothered looking and telling me to buzz off. ------------------------------------------------------------------------ [2002-03-02 02:16:52] yohgaki@php.net It's known problem..... Session become read only. Thanks for reporting but search reports first :) ------------------------------------------------------------------------ [2002-03-01 16:32:53] php@bradandkristin.com 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.
