To use a left join and group by in Laravel, you can use the query builder or Eloquent ORM. Here's an example using the query builder:

1

$data = DB::table('users')
            ->leftJoin('posts', 'users.id', '=', 'posts.user_id')
            ->select('users.id', 'users.name', DB::raw('count(posts.id) as post_count'))
            ->groupBy('users.id')
            ->get();


In this example, we are joining the users table with the posts table using a left join on the id column. We are then selecting the id and name columns from the users table, and calculating the count of posts.id as post_count using DB::raw(). Finally, we are grouping the results by users.id.


You can modify this query as needed to fit your specific requirements. Remember to replace users, posts, id, user_id, and name with your actual table and column names.
