In daily development, the php.ini configuration session.auto_start=0 closes the session by default if you want to open the session to call Session_Start:
- Session.auto_start automatically completes the session_start ()
- The difference is whether you need session_start () before using the session;
- when Session.auto_start = on , executing session_start () will produce a new session_id
- The advantage of Session.auto_start = On is that there is no time for forgetting to perform session_start () or session_start () in the wrong position in the program, resulting in an error
- The downside is that if you are using a third-party code, you must delete all of the session_start (). Otherwise you won't get the right results.
The above describes the difference between opening and closing session Auto_start in Phpini, including the contents of the content, I hope that the PHP tutorial interested in a friend helpful.
