This is the problem in WAP deployments where number of mobile phone browsers sends a Cookie in the form of: Cookie: PHPSESSID="xxx, PHPSESSID=xxx" (as denoted in http://bugs.php.net/bug.php?id=32111) This makes PHP to produce a warning: PHP Warning: Unknown(): The session id contains invalid characters, valid characters are only a-z, A-Z and 0-9 in Unknown on line 0 Reproduce code: --------------- session_set_cookie_params(3600); session_start(); var_dump(session_id()); Add ini_set('session.use_cookies', true); in the first request and ini_set('session.use_cookies', false); in the secodn. Expected result: ---------------- After the second request, session ID (as returned by session_id()) should not be same as after the first request. Actual result: -------------- The value returned by session_id() is the same within the first and second requests. I think that session.use_cookies is disabled, there should be no checking if the browser sends the cookie having the same name as session_name(). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32944&edit=1
