继续学习laravel框架，学习了视图的基本知识，通过路由对视图传递参数，通过控制器对视图传递参数数据。laravel中blade模板获取参数的时候只会获取数组中的下标作为变量，如果视图不是blade模板的时候，虽然也能通过这种方法传递参数，但在视图内就只能使用PHP语法就行操作。

创建控制器，模型，视图，

UserModel.php模型获取数据库中的数据实例

<?php

namespace App\Models\Admins;

use Illuminate\Database\Eloquent\Model;

class UserModel extends Model
{
    protected $table='user';
    protected $primaryKey='uid';
    function selectAll(){
        return $this->get()->toArray();
    }
}

User.php控制器控制数据实例

<?php

namespace App\Http\Controllers\Admins;

use App\Models\Admins\HomeModel;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Models\Admins\UserModel;

class User extends Controller
{
    public function index(UserModel $data){
        $res=$data->selectAll();
        $res['data']=$res;
        $res['nav']=[
            ['name'=>'演员','url'=>'https://www.baidu.com'],
            ['name'=>'导演','url'=>'https://www.163.com'],
        ];
        return view('/admins/user/user',$res);
    }
}
