i get request from android and IOS clients. I store the request in an array. then i encode it to JSON. Now i want to sent only the JSON data in my HTTP header. How to do that? Currently its sending the html page in response i want to send only json encoded data in 200 OK header.

Below is my code:

public function index()
{


    $request = array(
'request' => $this->input->get('request'),
'device_id' => $this->input->get('device_id'),
'launch_date'=> $this->input->get('launch_date'),
'allowed_hours'=>$this->input->get('allowed_hours'),
'site_id'=> $this->input->get('site_id'),
'product'=>$this->input->get('product'),
'software_version'=> $this->input->get('software_version'),
'platform_os'=> $this->input->get('platform_os'),
'platform'=> $this->input->get('platform'),
'platform_model'=> $this->input->get('platform_model')
    );

$response = array(
    'response_code' =>200 ,
    'device_id'=> $this->input->get('device_id'),
    'allowed_hours'=> $this->input->get('allowed_hours'),
    'product'=>'mlc',
    'prov_ur'=>NULL 
);





return $this->output
    ->set_content_type('Content-Type: application/json')
    ->set_output(json_encode($response));





    }
    }

MY response:

this is not a header problem your array do not have "allowed_hours" 

 Message: Undefined index: allowed_hours

you can change your code like this 

$allowed_hours = "";


if(!empty($this->input->get('allowed_hours'))){
$allowed_hours = $this->input->get('allowed_hours');
}
$response = array(
    'response_code' =>200 ,
    'device_id'=> $this->input->get('device_id'),
    'allowed_hours'=> $allowed_hours,
    'product'=>'mlc',
    'prov_ur'=>NULL 
);
