php - SessionHandler issue

Get the solution ↓↓↓

Solution:

why not modify SessionHandler::sessionWrite() to log debug_backtrace() info to a temporary log file. Then you can see this "blank" session and where sessionWrite was called from and realize what to fix? So just something easy like:

    public function sessionWrite($sessionId, $sessionData)
    {
        file_put_contents('test.txt',serialize(debug_backtrace()),FILE_APPEND);
        ......
    }
