Store CSV File in laravel 5

Hi Friends I am trying to store csv file in local laravel storage folder but I am getting this error Array to string conversion. please suggest me.

Controller

 $user=DB::table('users as u')
        ->join('emp as e', 'u.EmpID', '=', 'e.EmpID')
        ->select('e.DATE as Date', 'e.EmpID as EmpID', 'e.job as Work')
        ->get();
   $data = array();
    foreach ($user as $result) {
        $temp = (array)$result;  
        $temp['L'] = 'L';
        $data[] = $temp;

    }
    Storage::disk('csv')->put('users_'.date('m-d-y').'.csv',$data);

Expected Output in CSV File:

Date              EmpID       Work
25/08/16           123        House Cleaning
28/08/116          345        blahblah

Output Coming like this in CSV File:
