Question

我使用sql查询在codeigniter中生成一个sql字符串。

    $result['tc'] = $this->db->query("select * from stationList");

然后我将命令传递给视图：

    $this->load->view('jsontc',$result);

然后使用foreach循环将其更改为数组并将其编码为json：

    $emparray = array();

foreach ($tc as $row)
{

$emparray[] = $row;

}

$page = json_encode(array('stationList' => $emparray));
echo $page.

所以我得到以下结果

{
  "stationList":[
    {
  "no":"1",
  "location":"Temple Mall North",
  "districtL":"Kowloon",
  "districtS":"Wong Tai Sin",
  "address":"Temple Mall North Carpark, Level 3,\n136 Lung Cheung Rd, Wong Tai Sin, Kln",
  "provider":"CLP",
  "parkingNo":"320-322",
  "img":"\/EV\/PublishingImages\/common\/map\/map_thumb\/Entrance_Lung%20Cheung.jpg",
  "lat":"22.3425903320313",
  "lng":"114.190719604492",
  "type":"SemiQuick"
},

但如何为每组记录添加标题，如下所示？

{
  "stationList":[
    station{
  "no":"1",
  "location":"Temple Mall North",
  "districtL":"Kowloon",
  "districtS":"Wong Tai Sin",
  "address":"Temple Mall North Carpark, Level 3,\n136 Lung Cheung Rd, Wong Tai Sin, Kln",
  "provider":"CLP",
  "parkingNo":"320-322",
  "img":"\/EV\/PublishingImages\/common\/map\/map_thumb\/Entrance_Lung%20Cheung.jpg",
  "lat":"22.3425903320313",
  "lng":"114.190719604492",
  "type":"SemiQuick"
},
  station{...

为您的密钥选择唯一标识符非常重要，因此我选择了no您可以尝试：

foreach ($tc as $row)
{
   $emparray["{$row['no']}"] = $row;
}
