将数组php转换为Java

问题描述

我正在开发一个具有java文件和php文件的应用程序. Java文件调用php文件，这些文件在ddbb中执行查询，并将结果作为php数组返回，但将其打印在屏幕上.我把它像字符串一样用在Java中，我必须将其转换为和数组或集合，但是我不知道如何去做.

I am developing an app that has java files and php files. The java files call to the php files, these execute queries in the ddbb and return the result as an array php, but printing it in the screen. I take this in java like an string, and I have to convert it to and array or collection, but I have no idea how to do it.

php打印结果的一个示例是:

An example of the result that php prints is:

Array
(
[0] => Array
    (
        [id] => 1
        [0] => 1
        [name] => pepe
        [1] => pepe
    )

[1] => Array
    (
        [id] => 2
        [0] => 2
        [name] => antoñito
        [1] => antoñito
    )

[2] => Array
    (
        [id] => 3
        [0] => 3
        [name] => loló
        [1] => loló
    )

[3] => Array
    (
        [id] => 4
        [0] => 4
        [name] => ñoño
        [1] => ñoño
    )

[4] => Array
    (
        [id] => 5
        [0] => 5
        [name] => Antoñito
        [1] => Antoñito
    )

[5] => Array
    (
        [id] => 7
        [0] => 7
        [name] => José
        [1] => José
    )

)

如果我使用json_encode($ the_array)，这是结果:

If I use json_encode($the_array) this is the result:

[{"id":"1","0":"1","name":"pepe","1":"pepe"},    {"id":"2","0":"2","name":"anto\u00f1ito","1":"anto\u00f1ito"},{"id":"3","0":"3","name":"lol\u00f3","1":"lol\u00f3"},{"id":"4","0":"4","name":"\u00f1o\u00f1o","1":"\u00f1o\u00f1o"},{"id":"5","0":"5","name":"Anto\u00f1ito","1":"Anto\u00f1ito"},{"id":"7","0":"7","name":"Jos\u00e9","1":"Jos\u00e9"}]

谢谢大家

推荐答案

您应该为数据选择一种序列化方法.例如XML，协议缓冲区或JSON.

You should select a serialization method for your data. For e.g. XML, Protocol Buffers or JSON.

我个人建议您使用JSON，因为它是轻量级的，甚至对于人类来说也易于阅读，并且有两种语言可供选择的库.

I personally recommend you to use JSON because it's lightweight, easy to read even for humans and there are broad selection of libraries available for both languages.

$encoded = json_encode($data);

使用Jackson进行Java方面的解码

final ObjectMapper objectMapper = new ObjectMapper();
// the better way is to create a custom class with the correct format
final Map<?, ?> decoded = objectMapper.readValue(encoded, Map.class);
