Php 试图获得财产'；子目录名称'；非对象

我收到的错误：

public function product_view($id)
{
    $subcat = SubCategory::get();
    $data = DB::select('SELECT
                        sub_category.sub_cat_name, category.cat_name, product_images.prdt_image, product.prdt_name, product.actual_price, product.prdt_decription, product.id
                        FROM product
                        INNER JOIN category ON
                        product.catid = category.id
                        INNER JOIN product_images ON
                        product.id = product_images.prdt_id
                        INNER JOIN sub_category ON
                        product.sub_cat_id = sub_category.id
                        WHERE product.id=?', [ $id ]);

    return view("frontend.productreview", [
        'data' => $data,
        'subcat' => $subcat
    ]);
}

@foreach ($data as $prdt_data)
    <div class="pd-title">
        <span>{{ $prdt_data->sub_cat_name }}</span>

尝试获取非对象的属性“sub\u cat\u name”（视图：D:\xampp\htdocs\E-commerce\resources\views\frontend\productreview.blade.php）

控制器：

public function product_view($id)
{
    $subcat = SubCategory::get();
    $data = DB::select('SELECT
                        sub_category.sub_cat_name, category.cat_name, product_images.prdt_image, product.prdt_name, product.actual_price, product.prdt_decription, product.id
                        FROM product
                        INNER JOIN category ON
                        product.catid = category.id
                        INNER JOIN product_images ON
                        product.id = product_images.prdt_id
                        INNER JOIN sub_category ON
                        product.sub_cat_id = sub_category.id
                        WHERE product.id=?', [ $id ]);

    return view("frontend.productreview", [
        'data' => $data,
        'subcat' => $subcat
    ]);
}

@foreach ($data as $prdt_data)
    <div class="pd-title">
        <span>{{ $prdt_data->sub_cat_name }}</span>
        <h3>{{ $prdt_data->prdt_name }}</h3>

SQL显然写在一行中，但为了可读性，我更改了它

刀片模板：

public function product_view($id)
{
    $subcat = SubCategory::get();
    $data = DB::select('SELECT
                        sub_category.sub_cat_name, category.cat_name, product_images.prdt_image, product.prdt_name, product.actual_price, product.prdt_decription, product.id
                        FROM product
                        INNER JOIN category ON
                        product.catid = category.id
                        INNER JOIN product_images ON
                        product.id = product_images.prdt_id
                        INNER JOIN sub_category ON

    return view("frontend.productreview", [

这篇文章中有太多的内容实际上是代码，因此我需要写这一行。请忽略它。

var\u转储$subcat并查看它包含的内容。它（可能）是一个用于访问数据的arrayuse数组。您对所有这些代码有任何疑问吗？请将SQL放在代码中的单独行上，您需要能够读取它。lol它将正常工作。只需将$subcat转储并查看它包含什么。它（可能）是一个用于访问数据的arrayuse数组。您对所有这些代码有任何疑问吗？请在您的代码中保持SQL在单独的行上，您需要能够读取它。lol它将同样工作
