【问题描述】：

我试图从这样的 json 中读取一些统计信息，但我在某处犯了错误。我尝试了foreach 函数，但我不知道错误在哪里：

foreach($myDecodedStringFromJSon->playerStatsSummaries as $stats){
 // Do some here
}

这是我的 JSON：

{
   "summonerId":39656713,
   "playerStatSummaries":[
      {
         "playerStatSummaryType":"CAP5x5",
         "wins":0,
         "modifyDate":1431942577000,
         "aggregatedStats":{
            "totalChampionKills":3,
            "totalMinionKills":79,
            "totalTurretsKilled":0,
            "totalNeutralMinionsKilled":0,
            "totalAssists":4
         }
      },
      {
         "playerStatSummaryType":"CoopVsAI",
         "wins":22,
         "modifyDate":1431942577000,
         "aggregatedStats":{
            "totalChampionKills":73,
            "totalMinionKills":2344,
            "totalTurretsKilled":24,
            "totalNeutralMinionsKilled":0,
            "totalAssists":179
         }
      },
      {
         "playerStatSummaryType":"OdinUnranked",
         "wins":0,
         "modifyDate":1431942577000,
         "aggregatedStats":{

         }
      },
      {
         "playerStatSummaryType":"Unranked",
         "wins":18,
         "modifyDate":1431942577000,
         "aggregatedStats":{
            "totalChampionKills":63,
            "totalMinionKills":1789,
            "totalTurretsKilled":14,
            "totalNeutralMinionsKilled":5,
            "totalAssists":181
         }
      },
      {
         "playerStatSummaryType":"Unranked3x3",
         "wins":0,
         "modifyDate":1431942577000,
         "aggregatedStats":{

         }
      },
      {
         "playerStatSummaryType":"AramUnranked5x5",
         "wins":38,
         "modifyDate":1445430660000,
         "aggregatedStats":{
            "totalChampionKills":414,
            "totalTurretsKilled":28,
            "totalAssists":1556
         }
      }
   ]
}

【问题讨论】：

您能否为我们提供print_r($myDecodedStringFromJSon)。但据我猜测，你的字符串被解码为数组$myDecodedStringFromJSon['playerStatsSummaries']
我自己得到答案：stackoverflow.com/questions/3754411/php-json-stdclass-object
@George-Cristian 是的，您只需要 json_decode(string, true);这样就把它变成了一个数组。

【解决方案1】：

只需解码 JSON 并使用 foreach 循环。下面的代码会对你有所帮助。

$result = json_decode($json);
  foreach ($result->playerStatSummaries as $stats) {
  echo 'Wins: ' . $stats->wins;
  echo '<br>';
}
