Question

如果有人可以提供帮助，会很棒吗？我目前下面的数据是由底部的代码输出，但是比每个order_product_id重复的要多，我想从数据构建一个多级数组。

当前输出：

[0] => Array
        (
            [order_product_id] => 43
            [order_id] => 1
            [product_id] => 161
            [name] => Hoodie
            [model] => Hoodie
            [quantity] => 1
            [price] => 23.9500
            [total] => 23.9500
            [tax] => 0.0000
            [reward] => 0
            [option_id] => 141
            [option_name] => Hoodie Style
            [option_value] => Pull over
        )

    [1] => Array
        (
            [order_product_id] => 43
            [order_id] => 1
            [product_id] => 161
            [name] => Hoodie
            [model] => Hoodie
            [quantity] => 1
            [price] => 23.9500
            [total] => 23.9500
            [tax] => 0.0000
            [reward] => 0
            [option_id] => 142
            [option_name] => Hoodie Colour
            [option_value] => Light Pink
        )

    [2] => Array
        (
            [order_product_id] => 43
            [order_id] => 1
            [product_id] => 161
            [name] => Hoodie
            [model] => Hoodie
            [quantity] => 1
            [price] => 23.9500
            [total] => 23.9500
            [tax] => 0.0000
            [reward] => 0
            [option_id] => 143
            [option_name] => Adult Sizes
            [option_value] => Ladies Meduim 10-12
        )

所需数组，其中每个产品都具有多级别的所有选项，而不是当前设置如何显示它：

[0] => Array
        (
            [order_product_id] => 43
            [order_id] => 1
            [product_id] => 161
            [name] => Hoodie
            [model] => Hoodie
            [quantity] => 1
            [price] => 23.9500
            [total] => 23.9500
            [tax] => 0.0000
            [reward] => 0
            Array
                (
                [0] => Array
                    (
                    [option_id] => 141
                    [option_name] => Hoodie Style
                    [option_value] => Pull over
                    )
                [1] => Array
                    (
                    [option_id] => 142
                    [option_name] => Hoodie Colour
                    [option_value] => Light Pink
                    )
                [2] => Array
                    (
                    [option_id] => 141
                    [option_name] => Adult Sizes
                    [option_value] => Ladies Meduim 10-12
                    )
                )
        )

目前的输出正是由此构建的：

$sql = "SELECT site_order_product.*, 
site_order_option.order_option_id AS option_id, site_order_option.name AS option_name, site_order_option.value AS option_value
FROM site_order_product
INNER JOIN site_order_option ON site_order_product.order_product_id = site_order_option.order_product_id; ";

$result=mysqli_query($dbh2,$sql);
  if($result) {
            $row = mysqli_fetch_all($result,MYSQLI_ASSOC);
            return $row;
        } else {
            return false;
        }

感谢您的帮助！

注意：您看起来是延迟加载的功能。 ORM最适合   为你的问题。命名一些ORM的RedBean，Doctrine，Propel。

这只是为了演示的一个例子。

如果没有任何正确的数据库表架构，很难为您提供所需的确切答案输出。但是会帮助你做一些同样的例子。

认为您拥有产品表和订单表。

Products

id | product_name | product_price | product_notes

Orders

id | product_id | order_number

问题面对：现在，如果您查询产品，那么您将获得产品详细信息列表。但你面临的问题是获得各自的订单。

解决方案：当您循环到每个产品时，获取相应的产品ID并查询该产品的所有订单并分配到一个主阵列。

/* Get the list of products */
$productsQuery = mysqli_query($link, "SELECT * FROM products"); 
/* Array to hold the details or products and its respective order per product */
$productDetails = array(); 

if(mysqli_num_rows($productsQuery) > 0){
    $productCount = 0;
    while($product = mysqli_fetch_assoc($productsQuery)){
        $productId = $product['id'];

        /* Assign the product details to productDetails array */
        $productDetails[$productCount] = $product;

        /* Get the details of orders which respective productid */
        $ordersQuery = mysqli_query($link, "SELECT * FROM orders WHERE product_id = ".$productId);
        if(mysqli_num_rows($ordersQuery) > 0){
            while($order = mysqli_fetch_assoc($ordersQuery)){
                /* Here we have assigned the product orders to respective product */
                $productDetails[$productCount]['orders'] = $order;
            }
        }else{
            /* If no order assign an empty array */
            $productDetails[$productCount]['orders'] = [];
        }
    }
}

MySQL数据来自多级数组中的多个表
