session_destroy() destroys all of the data associated with the current session. It does not unset any of the global variables associated with the session, or unset the session cookie. To use the session variables again, session_start() has to be called.
它会destroys all of the data associated with the current session,但是它既不注销变量,又不注销session cookie。那它做了什么?还有这个函数有什么用呢?
