在PHP中获取cookie参数？

Question

How do you get a cookies params? The "expire, secure, httponly" etc.
Is it possible?

Answer 1

There isn't a way to get when a cookie is set to expire or any of the other parameters you are asking for using PHP. This is because PHP doesn't store anything like that, when you are setting a cookie, you are basically saying to output a header to the browser only once, then it's the job of the client (a browser) to send back the cookie data on each HTTP request. PHP therefore has no reason to retain the data, so it doesn't.

You can of course store when the cookie will expire in another cookie or a file somewhere, if you know where in your code the cookies are being set.
