What if php fails to clear cookie?

Reason why php cookie cannot be deleted

Cookie can be deleted through setcookie (name, value, expiration, path, host, secure, httponly)

If the cookie name is guaranteed to be the same and cannot be deleted, it means that the path parameter of cookie does not correspond to the result.

For example, if you are setting up cookie, this is it.

Setcookie ($key,$value,time () + 36000 fuzz')

Then when deleting, it must be like this.

Setcookie ($key, "", time ()-36000 jigsaw marks')

The slash after it means path, which must be consistent.
