Laravel 5 - DB join仅返回第一个表列集

I have some related MySQL tables, and I want to obtain the columns in all of them, but if I try with something like this code from the manual, I only get the columns from the first table:

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

That would be all columns from 'users' table, but I do not see contacts and orders columns.

try this

DB::table('users')->join('contacts',function($join){$join->on('users.id','=','contacts.user_id')})->join('orders',function($join){$join->on('users.id','=','orders.user_id')})->get()
