PHP session By default is stored in the server side of the file, and in the client using cookies to save variables, this will be a problem, when a user for some security reasons to shut down the browser's cookies, the program's session-related operations will not be able to execute. Therefore, if you can save session data in a database, you will not be limited by the client settings and have a leap in performance and scalability. The key function in the program is Session_set_save_handler, while

the initialization of a session object was established, because it is a new interview. So now there's no data in the session. The session is then read and written in the form of a key/value pair (do not forget that the session has all the dictionary operations), and then save the session by using the Save method. Assuming that the user is not new to the interview, then also according to the above process, only the session initialization when the previous data is taken out to save in the instanc

A large server traffic, because the program needs, the expiration of the session set is 3 hours, resulting in/tmp accumulation of nearly 200,000 of the session file. This leads to a sharp increase in the CPU consumed by the kernel. Because session reading and writing involves a lot of small files of random read and write, and is concentrated in a directory, iowait also increased dramatically. First consider putting the session into memory The easiest way to do this is to mount/tmp as a TMPFS f
