Ok comments dont seem to be working so change your code to this

include 'api/apiBase.php';

// following line changed
$farray = GetUserFriends($login->User_id);

echo $login->User_id . ' has ' . count($farray) . ' friends';

foreach ($farray as $idx => $value) 
{
    echo "Friend $idx has FriendId $value 
";
}

This line $farray[] = GetUserFriends($login->User_id); with the extra [] in is adding another level to the $farray that you dont need and is confusing you.
