那么'code'
属性是每个数组的唯一标识符吗？那么，在进行此操作之前，请先弄清楚：所有id
都是相同的1
？它们当前都设置为1，如果这使事情更容易，我可以更改此属性？只是询问一下（因为这确实使事情更容易）为什么名称ID始终为1的字段？这里$array代表什么？这是原始数组吗？我在这里测试了这种方法：它不获取日期键，只获取code
和id
。您可以使用该站点修复您的功能。看起来很不错。谢谢你的建议。日期现在是固定的，您可以在Runnable上测试它。我得到一个为$dataForEach（）提供的无效参数。我在这里测试了它：我在答案中发布的输出来自该站点的测试结果。让我看看我在复制/粘贴时是否键入了什么。我使用了您问题中第一块代码中的数组。当然，为了通过解析，我做了一些更改，比如删除[]
用引号包装键，提供逗号等，但是数据是一样的。您必须将该数组命名为$data
。再说一遍：这是您的数组，我只需为它提供一个名称$data
，并修复解析错误。另外，只要是2d数组，不同的数组也不应该是问题。如果需要解析print\u r的输出，这里有一个解决方案：请参阅此处注释中的函数print\u r\u reverse：
