Laravel 5.2 return no response as JSON

If i try to return a JSON-String by using return response()->json($categorie); i get an empty response. If i replace the return for echo, so i will get HTTP/1.0 200 OK Cache-Control: no-cache Content-Type: application/json {"id":5,"name":"blah","parent":4,"visible":"yes","position":0,"created_at":"2016-06-29 15:23:25","updated_at":"2016-06-29 15:23:25"} as Browser output.

I'm using Laravel 5.2. Here's the complete code:

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Categories;

class ApiController extends Controller
{
    public static function categorieGetById($id) {
        $categorie = Categories::find($id);
        echo response()->json($categorie);
        // return response()->json($categorie);
    }
}

UPDATE: the controller returns nothing. every return produce an empty output. why?

You should use toJson() method.

$categorie = Categories::find($id)->toJson();
echo $categorie;  // your json output
return $categorie; // same json output

The toJson method converts the collection into JSON.

in your current code,

$categorie = Categories::find($id);
return response()->json($categorie);  // your json output with return

Note:- You must write return here.

In above code if you write echo,

echo response()->json($categorie);

then it will show

HTTP/1.0 200 OK Cache-Control: no-cache Content-Type: application/json {"id":5,"name":"blah","parent":4,"visible":"yes","position":0,"created_at":"2016-06-29 15:23:25","updated_at":"2016-06-29 15:23:25"}

A qoute from http://laravel-tricks.com/tricks/return-json-response:

In the official docs : http://laravel.com/docs/responses#special-responses, need to do Response::json(...) to create json response. Actually, if the returned value is an array or instance of arrayableinterface or jsonableinterface such as eloquent model, you could just return it, it'll be a json, magically.
