You can do like this in JavaScript :

Just call delete_cookie function by passing your cookie name.

function delete_cookie(cookie_name)
{
  var cookie_date = new Date ( );  // current date & time
  cookie_date.setTime (cookie_date.getTime() - 1);
  document.cookie = cookie_name += "=; expires=" + cookie_date.toGMTString();
}

You can do like this in PHP :

setcookie("cookie_name", "", time()-3600);
