RE: [PHP] voting script

Well, dependant upon the need for accuracy, you could begin with the cookie idea. Then, if the cookie is refused, you could require a login or use the ip address as preference dicates.

And the third option is to require people to have an account on the website, so you can just flip a toggle on the account's entry for if they've answered the poll or not. However, this is no more foolproof than setting a cookie on the browser (Which the browser can easilly reject) In the end there's no assured way to prevent cheating. Requiring accounts makes it the most hassle to cheat, afaik. Setting a cookie will work for the majority of people, but it won't stop anybody who wants to cheat. All they have to do is not accept the cookie.
