title: Understanding session save path as no value and security
body: <p>I only use sessions to store variables and was hoping to ensure that the session save path could not be tampered with by any of the users. So I went to check my phpinfo and found that the session save path was set to no value. Is this normal for users who only use sessions for variables? Do I have anything to worry about if the sessions save path is set to no value? </p>
