Answer 1

post all friends wall at a time.

See, you have to use Feed API to post , one-by-one.

1. Get all the friends of the user:

   $facebook->api('/me/friends');
   

2. for each friend, use feed to post on their wall

   $params = array(
   'access_token'  => USER_ACCESS_TOKEN, 
   'message'       => 'Blah Blah',
   'link'          => URL
   );        
   
   $facebook->api('/FRIEND_ID/feed','POST',$params);
