【问题讨论】：

您试图解码的数据是什么形状的？如果您可以了解您尝试解码的数据，请在此处发布示例。
没有“JSON 数组”这样的东西。您要么有实际的 JSON，以字符串形式存在 - 但是在调用 json_decode 时没有理由会收到此错误 - 或者您没有。不要只向我们展示这样一条数据，这并不能帮助我们确定您的实际问题是什么 - 向我们展示该问题的正确minimal reproducible example。
我尝试从 CoinMarket 获取所有信息，我这样做了，我使用 CoinMarketCapApi::all_cryptos();显示所有数据，例如示例 .. 尝试将数据转换为像 ul li 一样查看 html .. 我不能帮助我
请分享您尝试过的代码

【解决方案1】：

先做json_encode()再做json_decode()，看看你得到了什么。

【讨论】：

有什么用？如果数据已经是数组格式或者对象格式，为什么还要先编码为json再解码？

【解决方案2】：

您只需将方法json_decode 中的第二个参数设置为true

点赞：json_decode($json, true);
