Question

我有一个来自金属交易所的JSON数组，我正在尝试从中获取AUD值

JSON在下面

{
    "GoldPrice": {
        "per": "gram",
        "date": "2013-01-23 11:51:48",

        },
        "PHP": {
            "currencyname": "Philippine Peso",
            "bid": "2203.9583"
        },
        "RUB": {
            "currencyname": "Russian Rouble",
            "bid": "1637.4859"
        },

            "bid": "96.0565"
        },
        "USD": {
            "currencyname": "United States Dollar",
            "bid": "54.2447"

            "bid": "489.4774"
        }
    }
}

我想要的部分是

“ AUD”：{ “ currencyname”：“澳元”， “ bid”：“ 51.4023” }

我想获取Bid值并将其加载到变量中。

如果有人可以像我尝试的那样提供帮助

$jsonArray = json_decode($json, true);
 echo $jsonArray->GoldPrice->AUD->bid;

但是什么也没显示。

任何帮助将不胜感激。

使用上面的代码，只需删除nginx.conf的{{1}}部分。

true标志使json_decode的输出成为一个关联数组，而不是将其保留为对象。使用, true进行访问会遍历对象。（PHP Manual: json_decode）

实际上，您有两个选择。

json_decode

或

->

我个人通常选择第二种方法。

PHP从JSON数组获取值
