Question

我有一个带键值的多维数组。我想循环数组中的数据，但我不知道如何。

这是我的阵列：

{
  "success": "1",
  "order_details": [
    {
      "item_order": 5,
      "address": "155, Mani Nagar Society, Nana Varachha, Surat, Gujarat 395006, India",
      "contact": "95303709",
      "total_price": "3330.0",
      "order_place": "18-05-25 06-07-20",
      "preparing_date_time": "",
      "preparing_status": "Deactivate",
      "dispatched_date_time": "",
      "dispatched_status": "Deactivate",
      "delivered_date_time": "",
      "delivered_status": "Deactivate",
      "menu": [
        {
          "menu_name": "demo item",
          "item_amt": "200",
          "Ingredients": [
            {
              "ingredients_name": "burger",
              "ingredients_price": "200"
            },
            {
              "ingredients_name": "pizza1",
              "ingredients_price": "800"
            }
          ]
        }
      ]
    }
  ]
}

如何循环/ foreach该数组？

我想foreach中有一个foreach，但我不知道该怎么做。

在array_walk_recursive的手册中，有一个可能适合你的例子 http://php.net/manual/en/function.array-walk-recursive.php

$arr = json_decode($str, true); //$str is your json string

array_walk_recursive($arr, 'test_print');

function test_print($item, $key)
{
    echo "[$key]: $item\n";
}

如果您只想输出数组的某些元素，可以创建一个包含要输出的项目的数组，并将其传递给函数。
然后使用in_array来查看它是否是输出。

使用此代码：

    <?php

$jsonData = '{
  "success": "1",
  "order_details": [
    {
      "item_order": 5,
      "address": "155, Mani Nagar Society, Nana Varachha, Surat, Gujarat 395006, India",
      "contact": "95303709",
      "total_price": "3330.0",
      "order_place": "18-05-25 06-07-20",
      "preparing_date_time": "",
      "preparing_status": "Deactivate",
      "dispatched_date_time": "",
      "dispatched_status": "Deactivate",
      "delivered_date_time": "",
      "delivered_status": "Deactivate",
      "menu": [
        {
          "menu_name": "demo item",
          "item_amt": "200",
          "Ingredients": [
            {
              "ingredients_name": "burger",
              "ingredients_price": "200"
            },
            {
              "ingredients_name": "pizza1",
              "ingredients_price": "800"
            }
          ]
        }
      ]
    }
  ]
}';

$jsonDecode = json_decode($jsonData);



foreach ($jsonDecode->order_details as $orderDetail) {

    echo "Item order: " . $orderDetail->item_order;
    echo "<br>";
    echo "Address: " . $orderDetail->address;
    echo "<br>";
    echo "Contact: " . $orderDetail->contact;
    echo "<br>";

    foreach ($orderDetail->menu as $menuItem) {

        echo "Menu Name: " . $menuItem->menu_name;
        echo "<br>";
        echo "Item amt: " . $menuItem->item_amt;
        echo "<br>";

        foreach ($menuItem->Ingredients as $ingredientsItem) {

            echo "Ingredients name: " . $ingredientsItem->ingredients_name;
            echo "<br>";
            echo "Ingredients price: " . $ingredientsItem->ingredients_price;
            echo "<br>";
        }
    }
}

输出：

Item order: 5
Address: 155, Mani Nagar Society, Nana Varachha, Surat, Gujarat 395006, India
Contact: 95303709
Menu Name: demo item
Item amt: 200
Ingredient name: burger
Ingredient price: 200
Ingredient name: pizza1
Ingredient price: 800
