To set the php survival validity period, we can use the session_set_cookie_params function or modify the php. ini file. The following is a brief introduction.

Method 1: session_set_cookie_params

Function prototype void session_set_cookie_params (int $ lifetime [, string $ path [, string $ domain [, bool $ secure = false [, bool $ httponly = false])

The code is as follows:

1. $ Lifetime = 3600; // one hour
2. Session_set_cookie_params ($ lifetime );
3. Session_start ();

Run the following code to manually set the Session lifetime:

2. Session_start ();
3. // Save for one day
4. $ LifeTime = 24*3600;
5. Setcookie (session_name (), session_id (), time () + $ lifeTime, "/");
6. ?>

Method 2:

If you have operation permissions on the server, it is very easy to set up, but you only need to perform the following steps:

1. set "session. use_cookies" to 1. enable the Cookie to store the SessionID. However, the default value is 1, which generally does not need to be modified;

2. change "session. cookie_lifetime" to positive infinity (of course there are no positive infinity parameters, but there is no difference between 999999999 and positive infinity );

3. set "session. gc_maxlifetime" to the same time as "session. cookie_lifetime;

4. modify the php. ini file session. gc. lifetime = 10000
