php - Laravel : How to store json format data in database? -

i want store json format data in database given array. how store using controller.

suppose have json data :

{"id":"bangladesh","divisions":[{"name":"barisal"},{"name":"chittagong"},{"name":"dhaka"},{"name":"khulna"},{"name":"rajshahi"},{"name":"rangpur"},{"name":"sylhet"}]} 

so far know in controller using json format i'm not aware of it.

public function saveuser(request $request)         {             $div=new div();                        $user->json = json_encode( array({"date 1": {                  {"id":"bangladesh","divisions":[{"name":"barisal"},{"name":"chittagong"},{"name":"dhaka"},{"name":"khulna"},{"name":"rajshahi"},{"name":"rangpur"},{"name":"sylhet"}]}                $div->save();              return redirect('getlist');         } 

how save in mysql list of divisions in division model using laravel controller?

you don't need convert array data json string yourself, use laravel $casts parameter on model: https://laravel.com/docs/5.2/eloquent-mutators#attribute-casting

you should in div model:

protected $casts = [     'divisions' => 'array', ];
