我想以count一個數(shù)字獲取我的查詢，目前它顯示所有記錄控制器： public function fetchCounts(){ $Result = $this->receivedModel->vehicleFreight($this->session->userdata('user_branch')); }模型：public function vehicleFreight($branch_id) { $this->db->select('*'); $this->db->from('truck_freight'); $this->db->where('truck_freight_status','truck_freight'); $this->db->where('fr_memo_to',$branch_id); $query = $this->db->get(); return $query->result(); } 我如何count()在我的查詢中使用。在我的數(shù)據(jù)庫中，我有 3 條記錄。

試試這個 模型
public function vehicleFreight($branch_id)
{
$this->db->select('count(*)');
$this->db->from('truck_freight');
$this->db->where('truck_freight_status','truck_freight');
$this->db->where('fr_memo_to',$branch_id);
$query = $this->db->get();
return $query->result();
}

獲得計數(shù)的多種方法
1 . echo count($query->result());
2 . echo $query->num_rows();
3 . You can use `count(*)` in `select` statement

要獲取獲取的記錄數(shù)，
$data = $query->result();
echo count($data); // use this as per your requirements
return $data;
