Answer 1

You can use the combination of laravel eloquent and Carbon

use Carbon\Carbon;
$news = New::select('id', 'title', 'created_at')
->get()
->groupBy(function($date) {
    return Carbon::parse($date->created_at)->format('Y');
});

Answer 2

By default we can make group by only with primary keys. if you want to add group by with other attributes you have to enable ONLY_FULL_GROUP_BY sql mode by adding the below code on config/database.php

'mysql' => [
    .....
    'modes' => [
        'ONLY_FULL_GROUP_BY',
    ],

recommended modes:

'STRICT_ALL_TABLES',
'ERROR_FOR_DIVISION_BY_ZERO',
'NO_ZERO_DATE',
'NO_ZERO_IN_DATE',
'NO_AUTO_CREATE_USER',
'NO_ENGINE_SUBSTITUTION',

once you enabled the mode then you can try the query here which returns the result group by year and month.

DB::table('posts')->groupBy([DB::raw("MONTH(posts_date)"), DB::raw("YEAR(posts_date)")])
->get();

I hope this will help you
