How to get data from multiple tables at once?

I need to retrieve data from the following object (debtor).

There are several tables, where the main table is tbl_devedor . After that, there are others, which are related to tbl_devedor .

Example:

  • tbl_devedor
  • tbl_email
  • id_contrato
  • id_telefone
  • id_endereco

Below is array 

$dados = array(
    'contratos' => [],
    'id' => '',
    'id_operador' => 0,
    'pessoa_fisica' => array(
          'id' => 0,
          'rg' => '',
          'dt_nascimento' => '',
          'profissao' => '',
          'salario' => '',
          'genero' => '',
        ),
    'pessoa_juridica' => array (
         'id' => 0,
         'nome_fantasia' => '',
         'inscricao_estadual' => ''
    ),
    'nome' => '',
    'cpf_cnpj' => '',
    'emails' => [],
    'enderecos' => [],
    'telefones' => [],
    'crud' => null
);

echo json_encode($dados);

Remembering that contratos , pessoa_fisicao , pessoa_juridica , emails , enderecos , telefones , comes from different tables, so far what I have is this:

Controller 

$devedor = $this->devedor->obter_por_id($id);

Model 

public function obter_por_id($id)
{
    $this->db->from($this->tbl_devedor);
    $this->db->where('id',$id);
    $query = $this->db->get();
    return $query->row();
}

I know how to join and get the data from the other tables, but I do not know how to get the structure of array .

Information being related , I would do a class Model for each table and then a Model to manage others as follows:

Minimum Example:

/ p>

  

class layout 

<?php

    class Devedor_model extends CI_Model 
    {

        public function obter_por_id($id)
        {
            $this->db->from('tbl_devedor');
            $this->db->where('id',$id);
            $query = $this->db->get();
            return $query->row_array();
        }

    }
  

class Devedor_model 

<?php

    class Devedoremail_model extends CI_Model 
    {   

        public function obter_por_id_email($id)
        {
            $this->db->from('tbl_devedor_email');
            $this->db->where('devedor_id',$id);
            $query = $this->db->get();
            return $query->result_array();
        }

    }

these two Model classes would now be used in another class Model that would manage and manipulate this data at once and will generate the% expected%: 

<?php

    class Devedordados_model extends CI_Model 
    {
        private $CI;

        public function __construct()
        {
            parent::__construct();
            $this->CI =& get_instance();
            // subindo as classe model coloque todas
            $this->CI->load->model("devedor_model");
            $this->CI->load->model("devedoremail_model");
        }

        public function obter_todos_dados_por_id($id)
        {
            $result = array();
            $result = $this->devedor_model->obter_por_id($id);
            $result['email'] = $this->devedoremail_model->obter_por_id_email($id);
            // insere aqui os outros models 
            //$result['enderecos'] = 
            //$result['telefones'] = 
            return $result;
        }

    }

and finally in Devedoremail_model is called the class that manages all Model , array : 

public function de()
{
    $id = 1;
    $this->load->model('Devedordados_model');

    echo json_encode($this->Devedordados_model->obter_todos_dados_por_id($id),
                     JSON_PRETTY_PRINT);

}

the result obtained by this method of controller : 

{
    "id": "1",
    "nome": "Devedor 1",
    "email": [
        {
            "id": "1",
            "email": "[email protected]",
            "devedor_id": "1"
        },
        {
            "id": "2",
            "email": "[email protected]",
            "devedor_id": "1"
        }
    ]
}

And this would be a proposal, by your doubt
