Преобразование PHP в каркас Codeigniter

Question

Пожалуйста, помогите, я не могу решить, как правильно конвертировать мой старый PHP в Codeigniter, чтобы получить результат JSON, как показано ниже.

{"data":[{"Category":{"Category_ID":"3","Category_name":"Camera","Category_image":"upload\/images\/7089-2015-07-09.png"}},{"Category":{"Category_ID":"9","Category_name":"Cars","Category_image":"upload\/images\/7789-2015-07-09.png"}},{"Category":{"Category_ID":"4","Category_name":"Clothes","Category_image":"upload\/images\/9350-2015-07-09.png"}},{"Category":{"Category_ID":"1","Category_name":"Computer","Category_image":"upload\/images\/1843-2015-07-09.png"}},{"Category":{"Category_ID":"7","Category_name":"Music","Category_image":"upload\/images\/8666-2015-07-09.png"}},{"Category":{"Category_ID":"5","Category_name":"Other","Category_image":"upload\/images\/6260-2015-07-09.png"}},{"Category":{"Category_ID":"2","Category_name":"Smartphone","Category_image":"upload\/images\/3025-2015-07-09.png"}},{"Category":{"Category_ID":"8","Category_name":"Sports","Category_image":"upload\/images\/5354-2015-07-09.png"}}]}

Это моя версия PHP

<?php
include_once('../includes/connect_database.php'); 
include_once('../includes/variables.php');


        $sql_query = "SELECT * 
                FROM tbl_category 
                ORDER BY Category_name ASC ";

        $result = $connect->query($sql_query) or die ("Error :".mysql_error());

        $categories = array();
        while($category = $result->fetch_assoc()) {
            $categories[] = array('Category'=>$category);
        }

        // create json output
        $output = json_encode(array('data' => $categories));

//Output the output.
echo $output;

include_once('../includes/close_database.php');?> 

Это мойверсия кодового ключа

public function prop_get() {

    //$data = null;
    $category = $this->db->get('kategori')->result();

    //$category = $this->Wilayah_model->get_category2();
    $categories[] = array('Category' => $category);

    $this->response(array('data' => $categories));

}

Спасибо

Вот как бы я это сделал (используя Query Builder, поскольку я фанат ...)

<?php
include_once('../includes/connect_database.php'); 
include_once('../includes/variables.php');

        // Using query builder for ease
        $db->order_by('Category_name ASC');
        $data = $db->get('tbl_category')->result_array();

        foreach ($data as $row){
            $categories[] = array('Category'=>$row);
        }

        $output = json_encode(array('data' => $categories));

Устраняет ли это вашу проблему?
