Laravel Eloquent, group by month/year

$result = ModelName::selectRaw('year(created_at) year, monthname(created_at) month, count(*) data')
                ->groupBy('year', 'month')
                ->orderBy('year', 'desc')
                ->get();

Note: This is solution based on eloquent, and yes, it not the best approach, but as the question is, this is using eloquent. If you want faster way, you can do it with raw query.

If you want to group your results for example by year, you can use closure where you will parse your datetime to desired format (year or month).

Here is example of the code:

$res= ModelName::where('someColumn','test')
      ->get()
      ->groupBy(function($val) {
      return Carbon::parse($val->created_at)->format('Y');
});

You can try as:

->select(DB::raw('count(id) as `data`'), DB::raw("DATE_FORMAT(created_at, '%m-%Y') new_date"),  DB::raw('YEAR(created_at) year, MONTH(created_at) month'))
->groupby('year','month')
->get();
