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 如下

}
}
我想要的部分是
"AUD": { "currencyname": "Australian Dollar", "bid": "51.4023" },
我想获取出价值并将其加载到变量中。
如果有人可以请帮助我已经尝试过
$jsonArray = json_decode($json, true);
echo $jsonArray->GoldPrice->AUD->bid;
但什么都没有显示。
任何帮助，将不胜感激。
有了你有上面的代码，只要将, true您的一部分json_decode。
true 标志使 json_decode 的输出成为关联数组，而不是将其保留为对象。访问 using->遍历对象。( PHP 手册: json_decode )
所以真的，你有两个选择。
$jsonArray = json_decode($json);
echo $jsonArray->GoldPrice->AUD->bid;
或者
$jsonArray = json_decode($json, true);
echo $jsonArray['GoldPrice']['AUD']['bid'];
就我个人而言，我通常会选择第二个选项。
