根据业务需求查出所需数据：
$data = DB::table('course_study_record')
    ->whereBetween('created_at',[$start_time,$end_time])
    ->groupBy('date')
    ->select([DB::raw('FROM_UNIXTIME(created_at,"%Y-%m-%d") as date'),DB::raw('COUNT(id) as value')])
    ->distinct()
    ->get();

array:6 [
  0 => array:2 [
    "date" => "2019-06-14"
    "value" => 6
  ]
  1 => array:2 [
    "date" => "2019-06-15"
    "value" => 5
  ]
  2 => array:2 [
    "date" => "2019-06-16"
    "value" => 1
  ]
  3 => array:2 [
    "date" => "2019-06-17"
    "value" => 2
  ]
  4 => array:2 [
    "date" => "2019-06-18"
    "value" => 1
  ]
  5 => array:2 [
    "date" => "2019-06-19"
    "value" => 1
  ]
]
