php - php json格式的问题

Question

我目前陷入 php 的 json 格式中。我在下面给出了我输出的 json。我需要做的是将当前json的格式设置为所需的格式。我缺少 JSON 格式的数组。谁可以帮我这个事。

我打印 json 输出的代码如下：

$menuHead=array(); 
$i=0; 
foreach($res as $key => $value){ 
    $i=$key+1;
    //$menuHead[$i]['menuHead']=$value['category'];
    if(isset($menuHead[$key]['menuHead'])){
        if($menuHead[$key]['menuHead']==$value['category']){
          $menuHead[$key]['data'][$i]['itemName']=$value['sub_category'];
          $menuHead[$key]['data'][$i]['price']=$value['price'];
          $menuHead[$key]['data'][$i]['description']=$value['description'];
          $menuHead[$key]['data'][$i]['itemId']=$value['id'];
          $menuHead[$key]['data'][$i]['customizable']=$value['customizable'];
        }else{
          $menuHead[$i]['menuHead']=$value['category'];
          $menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];  
          $menuHead[$i]['data'][$i]['price']=$value['price'];
          $menuHead[$i]['data'][$i]['description']=$value['description'];
          $menuHead[$i]['data'][$i]['itemId']=$value['id'];
          $menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
        }
    }else{
      $menuHead[$i]['menuHead']=$value['category'];
      $menuHead[$i]['data'][$i]['itemName']=$value['sub_category'];  
      $menuHead[$i]['data'][$i]['price']=$value['price'];
      $menuHead[$i]['data'][$i]['description']=$value['description'];
      $menuHead[$i]['data'][$i]['itemId']=$value['id'];
      $menuHead[$i]['data'][$i]['customizable']=$value['customizable'];
    }    
}
$final['MenuList']=$menuHead;
echo json_encode($final);

当前格式：

    {
  "MenuList": {
    "1": {
      "menuHead": "Main Course",
      "data": {
        "1": {
          "itemName": "Chicken Thai Curry",
          "price": "599",
          "description": "",
          "itemId": "67",
          "customizable": "1"
        }
      }
    },
    "2": {
      "menuHead": "Refreshments",
      "data": {
        "2": {
          "itemName": "Kingfisher Premium",
          "price": "999",
          "description": "Kingfisher beer",
          "itemId": "69",
          "customizable": "1"
        },
        "3": {
          "itemName": "Mocktail",
          "price": "999",
          "description": "",
          "itemId": "68",
          "customizable": "1"
        }
      }
    },
    "4": {
      "menuHead": "Rice biriyani",
      "data": {
        "4": {
          "itemName": "Dal makni risotto",
          "price": "499",
          "description": "Dal makhni risotto",
          "itemId": "66",
          "customizable": "1"
        }
      }
    }
  }
}

所需格式：

    {
  "menuList": [
    {
      "menuHead": "In Steamer (Momos)",
      "data": [
        {
          "itemName": "Tandoori Momo",
          "description": "",
          "price": "150",
          "itemId": "16",
          "customizable": "0"
        },
        {
          "itemName": "Fried Momo Pork",
          "price": "100",
          "description": "",
          "itemId": "15",
          "customizable": "0"
        }
      ]
    },
    {
      "itemName": "Rice and Noodles",
      "data": [
        {
          "sub_category": "Tandoori Momo",
          "description": "",
          "price": "150",
          "itemId": "16",
          "customizable": "0"
        },
        {
          "itemName": "Fried Momo Pork",
          "price": "100",
          "description": "",
          "itemId": "15",
          "customizable": "0"
        }
      ]
    }
  ]
}

原始响应如下：

数组(4) { [0]=> 数组(7) { ["id"]=> 字符串(2) "67" ["restaurant_id"]=> 字符串(1) "5" ["category"]=> string(11) "主菜" ["sub_category"]=> string(18) "泰式咖喱鸡" ["price"]=> string(3) "599" ["description"]=> string(0) " " ["customizable"]=> string(1) "1" } [1]=> array(7) { ["id"]=> string(2) "69" ["restaurant_id"]=> string(1 ) "5" ["category"]=> string(12) "Refreshments" ["sub_category"]=> string(18) "Kingfisher Premium" ["price"]=> string(3) "999" ["description "]=> string(15) "翠鸟啤酒" ["可定制"]=>string(1) "1" } [2]=> array(7) { ["id"]=> string(2) "68" ["restaurant_id"]=> string(1) "5" ["category" ]=> string(12) "Refreshments" ["sub_category"]=> string(8) "Mocktail" ["price"]=> string(3) "999" ["description"]=> string(0) " " ["customizable"]=> string(1) "1" } [3]=> array(7) { ["id"]=> string(2) "66" ["restaurant_id"]=> string(1 ) "5" ["category"]=> string(13) "Rice biriyani" ["sub_category"]=> string(17) "Dal makni risotto" ["price"]=> string(3) "499" [ "description"]=> string(18) "Dal makhni risotto" ["customizable"]=>字符串（1）“1”}}

如果你想要一个 javascript 兼容的数组，索引必须从 0 开始。最简单的方法是使用array_values()：

$final['MenuList'] = array_values($menuHead);
