I have got my friends list after getting logging in on facebook using Facebook connect Java script client API. I want list of my friends that are online at given time.
You can use the online_presence column of the user table, which gives the user s current Facebook Chat status. This isn t a foolproof "is this user online right now" but it does serve the general purpose as such. This column is a string which has one of four possible values: active, idle, offline, or error. Querying the friend table in conjunction with this can yield the result you requested (in this case I consider "online" to mean active or idle):
SELECT uid FROM user WHERE
online_presence IN ( active , idle )
AND uid IN (
SELECT uid2 FROM friend WHERE uid1 = $user_id
)
UPDATE:
Note that you need the user_status permission to read the user s status and user_online_presence and/or friends_online_presence permissions for the online_presence.
