Question

您好我解码此json字符串时遇到问题。我希望输入中的addr选项卡中的数据。我得到了这么远，但似乎无法让它发挥作用。因为它说他找不到索引：prev_out。

$obj = json_decode($json, true);
print_r($obj['inputs']['prev_out']['addr']);

提前致谢！ Json在下面： -

Answer 1

元素prev_out嵌套在另一个元素中。像这样访问它：

print_r($obj['inputs'][0]['prev_out']['addr']);

Answer 2

如果您还没有，请根据实际的json structure创建类，然后将其反序列化。如果您尊重这种格式，它将起作用。

无法解码此json字符串
