Laravel JOIN eloquent returns all rows from the both table, if there are matches in the both table. Otherwise, the result is NULL.

Example 1: Laravel Eloquent Join() with 2 Tables

$users = User::join('posts', 'users.id', '=', 'posts.user_id')
               ->get(['users.*', 'posts.descrption']);

When you dump the above-given laravel eloquent join query, you will get the following SQL query:

select `users`.*, `posts`.`descrption` from `users` 
inner join `posts` on `users`.`id` = `posts`.`user_id`

Example 2: Laravel Eloquent Join() with 3 Tables

In this example, get data using laravel eloquent join 3 table, you can see the following example:

$users = User::join('posts', 'posts.user_id', '=', 'users.id')
              ->join('comments', 'comments.post_id', '=', 'posts.id')
              ->get(['users.*', 'posts.descrption']);

When you dump the above-given laravel eloquent join 3 table query, you will get the following SQL query:

select `users`.*, `posts`.`descrption` from `users` 
inner join `posts` on `posts`.`user_id` = `users`.`id` 
inner join `comments` on `comments`.`post_id` = `posts`.`id`

Example 3: Laravel Eloquent Join() with Multiple Conditions

$users = User::join('posts', 'posts.user_id', '=', 'users.id')
            ->where('users.status', 'active')
            ->where('posts.status','active')
            ->get(['users.*', 'posts.descrption']);

When you dump the above-given laravel eloquent join with multiple conditions query, you will get the following SQL query:

select `users`.*, `posts`.`descrption` from `users` 
inner join `posts` on `posts`.`user_id` = `users`.`id` 
where `users`.`status` = active and `posts`.`status` = active

In another option instead of join laravel, you can use laravel relationship, once you created laravel relationship it will work like join.
