PHP Sessions and Cookies

I have a couple of questions regarding sessions and cookies: 1) Is there a way to append information to a cookie? I have read that it is, but I have also read many problems. Is there any particular way to do this? I ask this because cookies are being generated by two different types of scripts. However, they are both on the same site. So, I have access to them, no problem. I just want to append information to the same cookie. 2) If I append the PHP session id to every url, will PHP skip the cookies completely? I know this is more insecure. This option is only important if I cannot append information to the cookie.
