To join tables in Laravel, you can use the join() method available in the query builder.
You can specify the table you want to join with, as well as the columns to join on.
For example, if you have two tables users and posts, and you want to retrieve all posts along with the user information, you can join the two tables using their common field, usually the user_id field.
You can use the join() method like this:
$posts = DB::table('posts') ->join('users', 'users.
