laravel是怎么获取数组的？

Question

路由器写法：

Route::get('/', function () {


   $db=[
     'id'=>1,
     'name'=>'ok'

   ];

    return view('welcome',$db);
});

weclome 模版：

    @foreach($db as $v)           
             {{ $v->id }}
          @endforeach

报错：

ErrorException in 09a920b7dfeb8f66040a471f4982c97d line 42: Undefined variable: db (View: K:\demo\resources\views\welcome.blade.php)

这是为什么？

Answer 1

return view('welcome',['db' => $db]);

Answer 2

@foreach ($welcome as $v)
    {{ $v->id }}
@endforeach
