如何在codeigniter中创建json响应状态

Question

我使用json编码制作了json代码，结果是正确的，但我想向对象添加satatus响应。如何？

这是我的代码

public function get(){ 
header('Content-Type: application/json');
$db = $this->M_order->db_order();
$response =  array();
$data = array();
foreach ($db as $key) {
$data[] = array(
'id'    => $key->id_user,
'name'  => $key->name,
'destination' =>$key->destination
);
}
$response['data'] = $data; 
echo json_encode($response, TRUE);
}

这个结果是我的json

{
"data": [
{
"id": "1",
"name": "amar",
"destination": "USA"
}
]
}

在这里，我想在对象中添加一个状态标头，如下所示。。。

{
"status": 200,
"error": false,
"data": [
{
"id": "1",
"name": "amar",
"destination": "USA"
},
]
}

如何创建？

我理解你的问题，

$response =  array();
$data = array();
foreach ($db as $key) {
$data[] = array(
'id'    => $key->id_user,
'name'  => $key->name,
'destination' =>$key->destination
);
}
$response['status'] = 200;
$response['error'] = false;
$response['data'] = $data;
