Question

我有两个在同一个域上运行的应用程序实例，它们位于

主文件夹/
子文件夹/staging/

我正在"/staging"实例上测试一些代码。当用户退出时，我想完全清除所有他/她的cookie。

登录和注销在同一文件index.php.

要退出，用户必须点击带有她/他的链接index.php?action=logout

我在这里遇到的问题是，当用户注销不时，所有Cookie都会被删除。名为phone_call_timer的cookie不会被删除，除非我再次刷新注册（即index.php?action=logout）页面（2次），这对我来说没有，但这就是我所面对的！我不知道我的代码或PHP 5.5.12

所以我第一次去index.php?action=logout注销，但仍会保存1个cookie（即phone_call_timer）

但是，当我刷新（F5）页面“再次执行注销代码”时，cookie就会消失。

为什么第一次不删除phone_call_timer Cookie？我该如何解决这个问题？

注意：如果我导航到index.php或任何其他网址，则Cookie永远不会消失。

这是第一次注销后的屏幕截图（正如您所看到的那样phone_call_timer cookie仍然存在，但此时应该已将其删除。 enter image description here

这是我再次刷新退出页面后的屏幕截图（正如您可以看到phone_call_timer cookie现已消失！） enter image description here

这是我的PHP代码index.php文件
