循环遍历键下的嵌套数组

Question

好，这个标题可能有点误导人，但我不太确定我在描述什么，所以这里。

我有以下JSON:

{
  "lastModified": 1368517749000,
  "name": "Requiem Paradisum",
  "realm": "Chamber of Aspects",
  "battlegroup": "Misery",
  "level": 25,
  "side": 1,
  "achievementPoints": 1710,
  "emblem": {
    "icon": 126,
    "iconColor": "ffdfa55a",
    "border": 3,
    "borderColor": "ff0f1415",
    "backgroundColor": "ff232323"
  },
  "news": [
    {
      "type": "itemPurchase",
      "character": "Osmoses",
      "timestamp": 1368482100000,
      "itemId": 91781
    },
    {
      "type": "itemLoot",
      "character": "Greenmean",
      "timestamp": 1368477900000,
      "itemId": 87209
    },
    {
      "type": "itemLoot",
      "character": "Greenmean",
      "timestamp": 1368475800000,
      "itemId": 86880
    },
    {
      "type": "itemPurchase",
      "character": "Osmoses",
      "timestamp": 1368475380000,
      "itemId": 91781
    },
    {
      "type": "itemPurchase",
      "character": "Osmoses",
      "timestamp": 1368475380000,
      "itemId": 91779
    },
    {
      "type": "itemPurchase",
      "character": "Osmoses",
      "timestamp": 1368475320000,
      "itemId": 91779
    },
    {
      "type": "playerAchievement",
      "character": "Osmoses",
      "timestamp": 1368470700000,
      "achievement": {
        "id": 6193,
        "title": "Level 90",
        "points": 10,
        "description": "Reach level 90.",
        "rewardItems": [
          {
            "id": 87764,
            "name": "Serpent's Heart Firework",
            "icon": "inv_misc_missilelarge_green",
            "quality": 1,
            "itemLevel": 1,
            "tooltipParams": {
            },
            "stats": [
            ],
            "armor": 0
          }
        ],
        "icon": "achievement_level_90",
        "criteria": [
        ],
        "accountWide": false,
        "factionId": 2
      }
    },

基本上我需要遍历"news"中的所有内容并输出它。我不知道如何正确解析它:答:不指定密钥号码和B:当它到达一个键，然后在这些键下包含更多的键和更多的数组时，我就不知所措了。(例如"玩家成就"键)我很感激我在这里可能是一个新手，很可能在"php傻瓜"的第一页，但我发誓我已经谷歌死了!

Answer 1

看看这种方法是否合适。不过，请确保JSON数组的格式正确。

 $test = the_json_array;    
 $array = json_decode($test,true);
  function recursive($array) {
        foreach($array as $key => $value) {
            if (!is_array($value)) echo $key.":".$value."<br/>";
            else recursive($value);
        }
      }
 recursive($array);

Answer 2

参见json_decode

不要忘记给第二个参数作为TRUE，否则它将返回对象

，并尝试像这样

 $json         = 'your json'
 $json_array   = json_decode($json,true);
 $news         = $json_array['news'];
foreach($news as $value)
{
     print_r($value);
}

我想你应该看看array_walk_recursive

  function printResult($item, $key)
  {
     echo "$key holds $itemn";
  }
  array_walk_recursive($news, 'printResult');

Answer 3

你需要做json_decode('your-jason', True)，它会将你的Json字符串转换为数组。

Json_decode了解更多

如果在jason_decode函数中没有指定TRUE，那么它将返回php对象
