CURL's different Options values and their format

As you can see that every Option (parameter) when calling curl_Setopt requires a different mixed value format. where can i find a full description of how to use each of curl's options ? I mainly want to login to a page via curl have curl maintain the cookies post some fields while logged in then log off. but i still need to learn how to use each of the options used in PHP. can anyone recommend a good site? Thank you.
