推荐答案
取消设置将破坏特定的会话变量，而session_destroy()将破坏该用户的所有会话数据.
Unset will destroy a particular session variable whereas session_destroy() will destroy all the session data for that user.
这实际上取决于您的应用程序应该使用哪个应用程序.只要记住以上几点即可.
It really depends on your application as to which one you should use. Just keep the above in mind.
unset($_SESSION['name']); // will delete just the name data
session_destroy(); // will delete ALL data associated with that user.
