PHP注销SESSION的方法

本文介绍php对session的销毁操作

删除session方法

unset()

unset ($_SESSION['xxx']) 删除单个session
unset($_SESSION)销毁，而且还没有可行的办法将其恢复。用户也不再可以注册$_session变量
So千万不要用！

array()

$_SESSION = array()  删除多个session

session_destroy()

session_destroy()是注销所有的session变量,并且结束session会话
但在内存中的$_SESSION变量内容依然保留！！！

session_unset()

session_unset()并不注销session变量,但把所有的session变量的值清空

一般登出操作消除SESSION的方法

session_unset();
session_destory();
