php - 从对象创建关联数组

问题描述

我目前有一个通过循环对象使用正确数据构建的数组，但它给出的格式不正确：

$priceResult = array();

foreach($prices->categories as $category){ 

    $priceResult[] = $category->category_name;
    $priceResult[] = $category->category_desc;
    $priceResult[] = $category->category_code;

    foreach($category->products as $product){

        $priceResult[] = $product->product_info->item->item_code;

        foreach ($product->product_info->details as $details) {

            $priceResult[] = $details->description;
            $priceResult[] = $details->color;
            $priceResult[] = $details->sector;
        }

        $priceResult[] = $product->product_info->code;
        $priceResult[] = $product->product_info->item->description;
        $priceResult[] = $product->product_info->item->item_type->quantity;

        foreach(get_object_vars($product->prices) as $amount){

            $priceResult[] = $amount;

        }
    }
}

不过，这不是关联的。

所以目前，假设我有一个包含两种产品的类别，然后它们都打印为一个数组

array({
    1:category_name
    2:category_desc
    3:category_code
    4:item_code
    5:description
    6:color
    7:sector
    8:code
    9:description
    10:quantity
    11:amount
    12:item_code
    13:description
    14:color
    15:sector
    16:code
    17:description
    18:quantity
    19:amount
})

我想获得一个结构，其中父级别是 category_code 及其名称和描述，然后是每个 item_code 和他们自己的信息，如下所示：

array({
    category_name
    category_desc
    category_code
      Array(
       1: item_code array(
            details array(
                description
                color
                sector
            )
            code
            description
            quantity
            amount) 
       2: item_code array(
            details array(
                description
                color
                sector
            )
            code
            description
            quantity
            amount) 
 ) 
})

如何修改它以创建我需要的级别，以便在导出到电子表格时正确格式化

解决方案

您需要拆分代码并在循环中初始化新对象。

考虑以下（注意代码中的注释）

$allCategoryResult= array(); // init at first - notice naming as category and not prices

foreach($prices->categories as $category){ 
    $categoryItem = array(); // as current category to populate

    // give name to the keys and not just numbers
    $categoryItem["name"] = $category->category_name; 
    $categoryItem["desc"] = $category->category_desc;
    $categoryItem["code"] = $category->category_code;

    foreach($category->products as $product){
        $productItem = array(); // new product, so init new array for him

        // fill all the item data with name - maybe you will need to fix the paths here
        $productItem["details"] = array(); // init empty array for all the details elements
        foreach ($product->product_info->details as $details) {
            $detailsItem = array(); // init details array for each detail element
            $detailsItem["description"] = $details->description;
            $detailsItem["color"] = $details->color;
            $detailsItem["sector"] = $details->sector;
            $productItem["details"][] = $detailsItem; // add the detail element to the product array
        }

        $productItem["code"] = $product->product_info->code;
        $productItem["itemDescription"] = $product->product_info->item->description;
        $productItem["quantity"] = $product->product_info->item->item_type->quantity;
        $productItem["amount"] = get_object_vars($product->prices);

        $itemCode = $product->product_info->item->item_code;
        categoryItem[$itemCode] = $productItem; // add the product to category array by his code
    }
    $allCategoryResult[] = $categoryItem; //add the category to all category array
}

在没有看到实际数据的情况下编写这个非常困难 - 所以我想你必须修改它以适应你的数据。

但我希望你明白这一点。祝你好运！
