Question

我使用Core PHP在API中使用JSON输出产品列表，这里我需要在输出中进行一些修正。我只想在数组键中使用'body'，'dishes'和'dish_details'而不想将产品ID 18,26等显示为数组键。

如果我从循环中删除[$nid]，则仅打印最后的产品详细信息。

请参阅下面的代码：

foreach ($nodes as $nid => $node) {
    $output['dishes'][$nid]['dish_details']['dish_title'] =  $node->title;
    $output['dishes'][$nid]['dish_details']['dish_image'] =  $node->field_recipe_entities[$node->field_recipe]->field_recipe_image_url;
    $output['dishes'][$nid]['dish_details']['dish_price'] =  $node->field_recipe_entities[$node->field_recipe]->commerce_price_formatted;
    $output['dishes'][$nid]['dish_details']['dish_rating'] =  $node->rating;
    $output['dishes'][$nid]['dish_details']['dish_desc'] =  $node->desc;
    $output['dishes'][$nid]['dish_details']['dish_type'] =  $node->type;
    $output['dishes'][$nid]['dish_details']['dish_location'] =  $node->location;
}

$return = new stdClass();
$return->body = $output;
$return->message = "Dish list retrieved successfully.";
$return->error = 'nil';
$return->status = 200;

并查看我的输出：

{
  "body":{
     "dishes":{
        "18":{
           "dish_details":{
              "dish_id":"18",
              "product_id":"25",
              "dish_title":"Cogo Laoreet Roto",
              "dish_image":"http://localhost/drupal739/sites/default/files/dish_images/ima7070.tmp.png",
              "dish_price":"189.53  INR",
              "dish_rating":"",
              "dish_desc":{
                 "value":"Capto luctus nobis oppeto pagus torqueo veniam. Dolore eros hendrerit. Consectetuer genitus iaceo quia sed. Caecus commoveo dignissim elit melior modo refoveo tego vicis.\n\n",
                 "summary":null,
                 "format":"full_html",
                 "safe_value":"<p>Capto luctus nobis oppeto pagus torqueo veniam. Consectetuer genitus iaceo quia sed. Caecus commoveo dignissim elit melior modo refoveo tego vicis.</p>\n",
                 "safe_summary":""
              },
              "dish_type":"",
              "dish_location":""
           }
        },
        "26":{
           "dish_details":{
              "dish_id":"26",
              "product_id":"8",
              "dish_title":"Obruo Quibus",
              "dish_image":null,
              "dish_price":"500.00  INR",
              "dish_rating":"",
              "dish_desc":{
                 "value":"Amet aptent brevitas caecus commoveo consequat populus si. Distineo dolor esca gemino importunus metuo paratus tincidunt wisi.\n\n",
                 "summary":null,
                 "format":"full_html",
                 "safe_value":"<p>Amet aptent brevitas caecus commoveo consequat populus si. Distineo dolor esca gemino importunus metuo paratus tincidunt wisi.</p>\n",
                 "safe_summary":""
              },
              "dish_type":"",
              "dish_location":""
           }
        }
      }
    }
}

Answer 1

实际上你正在迭代foreach，你需要为每个节点提供索引，这样它们就不会覆盖这些值。

天气指定数组开头或中间的索引

$ouput[]['dishes']['anotherindex']['title'] = value;

将打印类似

的内容

0 : {
  "dishes" : {
      "anotherindex" : {
           "title" : {
              values here

Answer 2

如果您使用的是PHP 5.5并且想要搜索特定元素，那么您可以在没有循环的情况下使用以下内容：

//If 18 is one of the dishes key
$key = array_search('18', array_column($data['body'], 'dishes'));

if ($key !== false) {
    //Do something with that array segment
    var_dump($data['body'][$key]);
}

如何在没有数组键的情况下打印数组值
