The default session validity period in PHP is 1440 seconds (24 minutes) [weiweiok note: the default value in php5 is 180 minutes]. That is to say, if the client does not refresh for more than 24 minutes, the current session will become invalid. Obviously, this cannot meet the needs. One known method is to use session_set_save_handler to manage all sessions.
The default session validity period in PHP is 1440

: Some people say set session.timeout=-1, or less than 0 of the number. This method is certainly not possible, the session calculation time in minutes, must be greater than or equal to 1 integer.Others say set up session.timeout=99999. This is also not possible, the session has the maximum time limit. I have been tested and found that the maximum value is 24 hours, which means you can session.timeout=1440 the maximum.1441 can not have, hehe. I test en
the following configuration options:
Session. cookie_lifetime = 0; // set the cookie retention time (in seconds), which is equivalent to the session expiration time. 0 indicates that the browser is restarted.
Session. save_handler = files; // The method for saving and retrieving data. The default value is file. The storage mechanism is involved and is not extended here.
Of course, you can also use system functions without modifying the configuration file to achieve the same effect:

The code is as follows:
$ LifeTime = 24*3600; // save for one daySession_set_cookie_params ($ lifeTime );Session_start ();
On the server side, how does php determine whether the session file has expired?
The code is as follows:
Session. gc_maxlifetime = 1440 (initial value)# Set the session survival time in seconds. After each GC is started, the unix time for the last access to the session file is obtained through stat. if the current tim

In fact PHP5 session also provides a function session_set_cookie_params (); To set the lifetime of the PHP5 session, the function must be called before the session_start () function call:Copy the Code code as follows:$lifeTime = 24 * 3600; Save the daySession_set_cookie_params ($lifeTime);Session_Start ();
