推荐答案

您无法强制浏览器删除与任何Cookie相关联的文件，因为您不能保证实际上这样的文件 - 浏览器和Web服务器之间关于Cookie的合同是数据将在合格请求中显示。

You cannot force the browser to delete the file associated with any cookie, because you can't guarantee there's actually such a file - the contract between browser and web server regarding cookies is that the data will be presented at eligible requests.

您声明您不想等待cookie过期，但cookie过期是指示不再需要数据的正确方法，并且不应该在未来的请求中呈现，这在大多数情况下确实转换为浏览器移除文件。

You state that you "don't want to wait for the cookie to expire", but cookie expiration is the correct method for indicating that the data is no longer needed and should not be presented on future requests, which in most cases does translate to the browser removing the file.

因此，要删除Cookie，请将其过期时间设置为过期时间。在PHP中，这是通过 setcookie（） 。

To delete a cookie, therefore, set its expiration time into the past. In PHP, this is done with setcookie().
