when I'm trying to get this using facebook graph explorer it is giving me right result. I've used app_access_token and user-access-token.. what is wrong with facebook graph api.

What do you mean with wrong user_id? Could it be that you get an app scoped user id back? – Atli

I mean first few character of user_id are same but other are different. I have cross checked this using the name variable in the response JSON. names are same but user_id are different. – Twilley

Sounds like a app scoped user id to me. But you can always report it as a bug on developers.facebook.com/bugs and someone will look into it – Atli

can you explain me what is app scoped user id?? – Twilley

Facebooks upgrade guide explains it: developers.facebook.com/docs/apps/… – Atli

You are probably talking about "App Scoped IDs": https://developers.facebook.com/docs/apps/upgrading#upgrading_v2_0_user_ids

Apps don´t return real User IDs anymore, only IDs bound to one specific App. The Graph API Explorer should return the exact same ID for a User, as long as you select the same App before making an API call.
