Get cookie according to domain

I开发者_运维知识库 want to reset all previous cookie for particular domain. Is there any way so I can get all the cookie for particular domain? Right now cookie I have cookies for google and my site. I want cookies only for my site.

Expiring ( removing ) a cookie uses the same command as creating a cookie. The cookie value is left blank and the expiration time needs to be in the past.

To expire the cookie ‘mycookie’ use:

setcookie('mycookie','',1);

To retrieve cookie information, use:

// Print a cookie
echo $_COOKIE["mycookie"];

// View all cookies
print_r($_COOKIE);

You cannot get any more information than the information you store in the cookie. The cookie is not stored on the server, but on the client computer, that is the immediate reason why you can't get more information about the cookie.

I hope this is sufficient information to be an answer to you.
