If you follow the documentation, a call to session_write_close(), session_name('MyNewSession') and session_start() should be sufficient to switch from one session to another, but it's not the case. Description: ------------ I want to open a existing session, read data in it, close it and then create a new session. Reproduce code: --------------- 1) Call 'set_sess1.php' to set a session named 'sess1': <?php session_name('sess1'); session_start(); $session_id = session_id(); // Do some stuff in sess1 $_SESSION['sess1']='session1:'.$session_id; // Print session content echo 'Session 1:<br />'; print_r($_SESSION); session_write_close(); ?> 2) Try to access 'sess1' data first AND THEN to create 'sess2' in the same script in 'view_sess1_create_sess2.php': <?php ob_start(); // session_name('sess1'); session_start(); // Do some stuff in sess1 $_SESSION['mydata'] = 'new update in sess1'; // Print session content echo 'Session 1:<br />'; print_r($_SESSION); // Save data into sess1 session_write_close(); // Create sess2 session_name('sess2'); session_start(); $session_id = session_id(); // Do some stuff in sess2 $_SESSION['sess2']='session2:'.$session_id; $_SESSION['mydata'] = 'new update in sess2'; // Print session content echo '<br /><br />Session 2:<br />'; print_r($_SESSION); session_write_close(); ob_end_flush() ?> Expected ouptut result: ----------------------- Session 1: Array ( [sess1] => session1:f0ed9cecd7a730784a9f6aed4c241887 [mydata] => new update in sess1 ) Session 2: Array ( [sess2] => session1:db0c904dd716126ddfc8e3db30e1ddda [mydata] => new update in sess2 ) Expected Set-Cookie header (SID different from sess1): ------------------------------------------------------ Set-Cookie: sess2=db0c904dd716126ddfc8e3db30e1ddda; path=/ Actual output result: --------------------- Session 1: Array ( [sess1] => session1:f0ed9cecd7a730784a9f6aed4c241887 [mydata] => new update in sess1 ) Session 2: Array ( [sess1] => session1:f0ed9cecd7a730784a9f6aed4c241887 [mydata] => new update in sess2 [sess2] => session2:f0ed9cecd7a730784a9f6aed4c241887 ) Actual Set-Cookie header (same SID as sess1): --------------------------------------------- Set-Cookie: sess2=f0ed9cecd7a730784a9f6aed4c241887; path=/ So php dosn't close sess1 properly, so the session still have the same SID. The patch I found is to use session_regenerate_id(false) and some patch: Patched code: ------------- <?php session_name('sess1'); session_start(); // Do some stuff in sess1 $_SESSION['mydata'] = 'new update before creating sess2'; // Save data into sess1 session_write_close(); // Create sess2 with sess1 id without resending a Set-Cookie header // Resending a Set-Cookie header would create a cookie sess2=<sess1_id> // Furthermore, if you don't do the session_start() here, session_regenerate_id // will have no effect ini_set('session.use_cookies',0); session_name('sess2'); session_start(); ini_set('session.use_cookies',1); // Create a new genuine session id and do the actual session_id($new_sess_id) silently, // then send a cookie to the client with the new id sess2=<new_sess2_id> $old_sess_id = session_id(); session_regenerate_id(false); $new_sess_id = session_id(); echo '<br />old : ' . $old_sess_id; echo '<br />new : ' . $new_sess_id; ?> ------------------------------------------------------------------------ [2008-12-17 08:20:35] vijaybabur at mobiusservices dot in I also facing the same problem (Different sessions in one page). ------------------------------------------------------------------------ [2008-11-17 09:14:44] ritenvs1987 at yahoo dot com I am facing the same problem, cannot access sessions with different names on the same page. ------------------------------------------------------------------------ [2008-11-13 16:45:27] jd at jdfitzgerald dot net The problem I'm having is actually bug #45270, which the powers that be have decided to mark as bogus related to this one. I hope it doesn't fall by the wayside due to this (poor?) decision. The work-around I've found is to ini_set('session.use_cookies',0) after the first session_start. This will stop any further set-cookie headers being sent after the first one, with no ill effects that I've noticed. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
