How define json header in codeigniter controller?

Question

I want to show response in json format in controller and don't want to move in view. So, please let me any way so that I can show json response.

Here is the code where i want to add json headers.

$result = $this->mod_doc->get_list();   
echo json_encode($result);

Just give these a try.

public function signin() {
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);    

//add the header here
header('Content-Type: application/json');
echo json_encode( $arr );
}

or Try this way

return $this->output
        ->set_content_type('application/json')
        ->set_status_header(200) // Return status
        ->set_output(json_encode(array(your array)));

only header('Content-Type: application/json'); worked for me

There is no need to change the header status to 500, this can be excluded set_status_header(500)

The second one is way much better than writing header eachtime Works smoothly

$result = $this->mod_doc->get_list();
$this->output
    ->set_content_type('application/json') //set Json header
    ->set_output(json_encode($result));// make output json encoded

$response = array('status' => 'OK');

$this->output
        ->set_status_header(200)
        ->set_content_type('application/json', 'utf-8')
        ->set_output(json_encode($response, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES))
        ->_display();
exit;
