• user_id
• first_name
• last name

and not able fetch

• email
• phone

• birthday etc

  $request = new facebookrequest(   $session,   'get',   '/group_id/members',   array(     'fields' => 'id,first_name,last_name,email,gender,birthday'   ) );  $response = $request->execute(); $graphobject = $response->getgraphobject(); 

when write limit parameter(2000) in code getting following error

please reduce amount of data you're asking for, retry request.

do error message tells , reduced amount. instead, use paging members: https://developers.facebook.com/docs/graph-api/using-graph-api#paging

btw, you can email , birthday of people authorized app correct permissions (email , user_birthday), , can´t phone number @ all. not allowed store or use data of user anyway without specific permission/authorization.

also, can´t more 5000 members, see thread more information: https://stackoverflow.com/questions/26990562/how-do-i-bypass-the-facebook-graph-api-bug-and-get-more-than-5000-members-from-a

...but don´t accepted answer suggests, because scraping - not allowed on facebook.
