PHP cookie 过期

Question

我对 Cookie 不熟悉，希望让此 Cookie 在我的注销页面上过期

这是我设置 cookie 的位置:

   setcookie("loggood", "YES", $expire, "/", "", 0);  
    setcookie("user", $pid, $expire, "/", "", 0);    

任何人都可以帮助我如何使 cookie 过期以便用户可以注销吗？

谢谢

Answer 1

如果你想删除cookie，只需将$expire时间设置为过去即可:

setcookie("loggood", "", time() - 3600);
setcookie("user", "", time() - 3600);

来自PHP documentation的笔记:

When deleting a cookie you should assure that the expiration date is in the past, to trigger the removal mechanism in your browser.
