When the browser is closed, the session data on the server is not destroyed, because no request is sent at this time, and the server does not know whether to destroy the session data. When the browser restarts and re-opens the page, the session id sent is still the original id. Although you say no cookie is used, this id is sent through the cookie.

You can check the settings of php. ini, mainly including the following two items:

The code is as follows: Copy code
Session. gc_maxlifetime
Session. cookie_lifetime

Method 2 use the onload function

The code is as follows: Copy code

<Body onunload = "ajax ()">
Function ajax (){
Execute unset ($ _ session) using ajax );
