Detailed explanation of setting session survival time in php_PHP tutorial

To set the php survival time, we can use the session_set_cookie_params function or modify the php.ini file. Let me introduce it below.

The first method: 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

代码如下	复制代码
$lifetime = 3600;    //一个小时 session_set_cookie_params($lifetime); session_start();

Copy code

代码如下	复制代码
session_start(); // 保存一天 $lifeTime = 24 * 3600; setcookie(session_name(), session_id(), time() + $lifeTime, “/”); ?＞

$lifetime = 3600; //One hour

session_set_cookie_params($lifetime);

session_start();

Manually set the Session lifetime:

The code is as follows	Copy code

session_start();

// Save for one day

$lifeTime = 24 * 3600; setcookie(session_name(), session_id(), time() + $lifeTime, “/”); ?＞ Second method: If you have the permission to operate the server, then setting this up is very, very simple. You just need to follow the following steps:

1. Set "session.use_cookies" to 1 and turn on Cookie to store SessionID, but the default is 1 and generally does not need to be modified; 2. Change "session.cookie_lifetime" to positive infinity (of course there is no parameter for positive infinity, 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
