Example 1: laravel join
Inner Join : ->join('contacts', 'users.id', '=', 'contacts.user_id')
Left Join : ->leftJoin('posts', 'users.id', '=', 'posts.user_id')
Right Join : ->rightJoin('posts', 'users.id', '=', 'posts.user_id')
Cross Join : ->crossJoin('colors')
Advance Queries :
-----------------
->join('contacts', function ($join) {
$join->on('users.id', '=', 'contacts.user_id')
->where('contacts.user_id', '>', 5);
})
Example 2: laravel join

$users = DB::table('users')
->join('contacts', 'users.id', '=', 'contacts.user_id')
->join('orders', 'users.id', '=', 'orders.user_id')
->select('users.*', 'contacts.phone', 'orders.price')
