Answer 1

Not knowing your exact db setup, but something like this is how you would do this query using CodeIgniter's Active Record

 $this->db->select('places.place_id');
 $this->db->select_sum('places.place_id', 'total');
 $this->db->from('places');
 $this->db->join('users', 'places.place_id = user.place_id', 'left');
 $this->db->group_by('user.place_id');
 $this->db->get();
