PHP sessions default timeout
提问by KB.
Do PHP sessions timeout by default - ie without any coding on my part would a user eventually be "logged out" after some time of inactivity?
PHP 会话是否默认超时 - 即如果我没有任何编码，用户在一段时间不活动后最终会“注销”吗？
回答by Niet the Dark Absol
It depends on the server configuration or the relevant directives session.gc_maxlifetimein php.ini.
这取决于服务器配置或相关指令session.gc_maxlifetimein php.ini。
Typically the default is 24 minutes (1440 seconds), but your webhost may have altered the default to something else.
通常默认值为 24 分钟（1440 秒），但您的虚拟主机可能已将默认值更改为其他内容。
