Mysql laravel 5.2查询-htmlentities（）要求参数1为字符串，对象为给定的

我试图在我的网站上输出所有零售商的价格，但是当我在查询的末尾使用->get（）时，它显示了这个错误

htmlentities（）要求参数1为字符串，对象为给定值

代码：

但是当我使用->first（）而不是->get（）时，查询是成功的，并且所有内容都正确地显示在我的网站上

$price = \DB::table('cpus')->where('slug' ,'=', $slug)->join('prices', 'cpus.model', '=', 'prices.model')->join('retailers', 'retailers.id', '=', 'prices.retailer_id')->select('prices.price', 'prices.url')->first();

如何显示所有记录而不是一条记录，使用->get（）会有什么问题

控制器：

$price = \DB::table('cpus')->where('slug' ,'=', $slug)->join('prices', 'cpus.model', '=', 'prices.model')->join('retailers', 'retailers.id', '=', 'prices.retailer_id')->select('prices.price', 'prices.url')->first();

    $data = [
          'price' => $price
          ];
     return view('part', $data);

看法

---

基本上，foreach中的两个值中有一个或多或少是数组etc，而不是字符串

通过在foreach之后添加

{{{dd（）}}

来调试它，以获取其输出的值，查看结果是什么。类似于

 @foreach ($price as $p => $value)

      {{dd($p)}}    

    <h5> {{$p}}</h5> <br>
    <p>{{$value}}</p>
 @endforeach

---

但是先看看dd生产的etc的模型<代码>获取获取一个集合。您显示的代码不是问题所在，我不相信，问题出在您使用

$price

的控制器或视图中。显示给我们看。用视图和控制器更新问题，我在哪里使用$price我不认为你的错误在那里，无论如何，你使用的是LaraveCollective吗？比如{{HTML:：}}？我不使用它，只使用普通的旧HTML。我添加了完整的eror，也许这有助于解决问题。你能发布完整的控制器方法和完整的视图页面吗？我并没有完全理解你刚才想说的，但是{dd（$p}}}的输出只是'0'和{dd（$value）}的输出这样可以吗，所以$value的值是一个数组，所以需要像{{{$value->price}一样输出它

为了避免实体错误，因为它无法解析数组，希望这有助于避免看到您在上面编辑了答案，现在我也得到了答案，它像多维数组一样输出。我只需要使用2个循环来输出它。非常感谢m8帮助我：）

@foreach ($price as $p => $value)
<h5> {{$p}}</h5> <br>
<p>{{$value}}</p>
@endforeach
