laravel 视图使用

1 在app/Admin/Controllers 创建 viewtestController.php

<?php
namespace App\Admin\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\DB;

class SqltestController extends Controller
{
    public function index()
    {
  $users = DB::table('user_age')->select('username', 'userid')->get();
  return view('index', ['data'=>$users]);
    }
}

2 .在 /resources/views 下自主创建 index.blade.php

@foreach($data as $key=>$value)
    {{$value->username}}
@endforeach
