在codeigniter中将查询结果作为数组获取

Question

我有一个查询，如何将结果作为数组？

function get_all_transaksi_proses() {
    $rs = $this->db->query("SELECT a.id_transaksi,
                                   a.nama,
                                   a.tgl_transaksi, 
                                   (SELECT COUNT( id_transaksi ) AS jum  
                                     FROM  tbl_detail_trs_menu  
                                     WHERE id_transaksi = a.id_transaksi)  AS jumlah, 
                                   a.status_transaksi, 
                                   a.total, 
                                   b.status_pelanggan, 
                                   c.nama_karyawan 

                            FROM   tbl_transaksi a 

                                   LEFT JOIN  tbl_pelanggan b 
                                      ON a.id_pelanggan = b.id_pelanggan 

                                   LEFT JOIN tbl_karyawan c 
                                      ON a.id_karyawan = c.id_karyawan 

                            WHERE  a.status_transaksi =  'PROSES' ");  

  echo json_encode(array("result" => $rs)); 
}

Answer 1

像这样：

$rs = $this->db->query(...);
$array = $rs->result_array();

Answer 2

要在数组中获得结果，您必须执行此CI 2.2.2：

    return $query->result_array();

Answer 3

$query = $this->db->query("select....");

return $query->result(); // it will result an array
or
echo json_encode($query->result()); // this will also result array but direct to json_encode
