PHP-如何知道数组对象中的最新数组？

我试图从一个以json形式到达的对象获取数据，我将其转换为一个对象数组，并查找一个值中的数组数量。因此，我需要知道此阵列中哪一个是最新的阵列

例如：

Array
(
    [response] => Array
        (
            [0] => Array
                (
                    [canalAtendimento] => URA
                    [IdentificadorParceiroNegocio] => 
                    [IdentificadorInstalacao] => 7008000000
                    [Ani] => 21981737137
                    [DataInicio] => 
                    [HoraInicio] => 
                    [DataFim] => 04/05/2021
                    [HoraFim] => 09:42:25
                    [Dnis] => 
                    [MenuAtend] => 
                    [DocCliente] => 
                    [EnderecoVocalizado] => 
                    [Protocolo] => 
                    [GuidProtocolo] => 
                    [IdentificacaoNotaServico] => 
                    [Funcionalidade] => 
                    [Descricao] => 
                    [Usuario] => 
                    [NsDetails] => 
                    [created] => 04/05/2021 09:39:15
                )

            [1] => Array
                (
                    [canalAtendimento] => URA
                    [IdentificadorParceiroNegocio] => 
                    [IdentificadorInstalacao] => 7008000000
                    [Ani] => 21981737137
                    [DataInicio] => 04/05/2021
                    [HoraInicio] => 09:43:00
                    [DataFim] => 04/05/2021
                    [HoraFim] => 09:45:14
                    [Dnis] => 
                    [MenuAtend] => 
                    [DocCliente] => 
                    [EnderecoVocalizado] => 
                    [Protocolo] => 
                    [GuidProtocolo] => 
                    [IdentificacaoNotaServico] => 
                    [Funcionalidade] => 
                    [Descricao] => 
                    [Usuario] => 
                    [NsDetails] => 
                    [created] => 04/05/2021 09:42:01
                )

            [2] => Array
                (
                    [canalAtendimento] => URA
                    [IdentificadorParceiroNegocio] => 
                    [IdentificadorInstalacao] => 7008000000
                    [Ani] => 21981737137
                    [DataInicio] => 04/05/2021
                    [HoraInicio] => 10:15:51
                    [DataFim] => 04/05/2021
                    [HoraFim] => 10:16:25
                    [Dnis] => 
                    [MenuAtend] => 
                    [DocCliente] => 
                    [EnderecoVocalizado] => 
                    [Protocolo] => 
                    [GuidProtocolo] => 
                    [IdentificacaoNotaServico] => 
                    [Funcionalidade] => 
                    [Descricao] => 
                    [Usuario] => 
                    [NsDetails] => 
                    [created] => 04/05/2021 10:13:12
                )

            [3] => Array
                (
                    [canalAtendimento] => URA
                    [IdentificadorParceiroNegocio] => 
                    [IdentificadorInstalacao] => 7008000000
                    [Ani] => 21981737137
                    [DataInicio] => 04/05/2021
                    [HoraInicio] => 10:36:21
                    [DataFim] => 04/05/2021
                    [HoraFim] => 10:37:31
                    [Dnis] => 
                    [MenuAtend] => 
                    [DocCliente] => 
                    [EnderecoVocalizado] => 
                    [Protocolo] => 
                    [GuidProtocolo] => 
                    [IdentificacaoNotaServico] => 
                    [Funcionalidade] => 
                    [Descricao] => 
                    [Usuario] => 
                    [NsDetails] => 
                    [created] => 04/05/2021 10:34:43
                )

        )

)

我在数组响应中有4个数组。0、1、2和3。在本例中，根据DataFim和HoraFim，3是最新的，但数据可能是随机的。因此，我需要知道如何根据DataFim和HoraFim获取最后一个数组

有什么办法吗

如果直接使用json结果执行查询更好，我接受建议。

您需要使用group by DataFim和HoraFim以及order by desc limit 1进行select查询，这样您可以选择最新的数组

使用group by和order by desc的查询示例

"Select * from table_club Group by DateFim , HoraFim Order By DateFim,HoraFim Desc limit 1"

使用

usort

并编写自定义日期比较函数。您可以对数组进行排序，然后根据顺序的方向（从最新到最旧或其他方式）选择第一个/最后一个元素。问题与SQL无关。在PHP中使用此查询可以解决问题，查询结果必须提供最新的数组在这种情况下，您需要一个按DateFim和HoraFimsorry进行筛选的筛选方法。抱歉，这不是SQL，reult是json格式的。这是一个rest api，我在json中查阅并返回给我。json中的这个值的返回方式如下：

{“response”：[{“CanalatedIndimento”：“URA”，“DataFim”：“04\/05\/2021”，“HoraFim”：“09:42:25”，…}，{“CanalatedIndimento”：“URA”，…}]}

，我需要知道哪一个是最新的对象才能从最新的对象获取值。
