将数组php转换为java

Question

我正在开发一个有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，并以数组php的形式返回结果，但在屏幕上打印出来。在java中，我把它当作一个字符串，我必须把它转换成and数组或集合，但我不知道该怎么做。

php打印的结果示例如下：

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)，结果如下：

[{"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

Answer 1

您应该为数据选择一种序列化方法。例如，XML、Protocol Buffers或JSON。

我个人建议您使用JSON，因为它是轻量级的，即使对于人类来说也很容易阅读，而且两种语言都有广泛的库可供选择。

在PHP端进行编码

$encoded = json_encode($data);

用Jackson在Java端解码

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);

Answer 2

使用一些更标准化的传输格式，比如JSON。PHP端必须使用json_encode()对数组进行编码，而Java端需要一些库来解码它(参见相关的question)。

我认为这可能是有用的http://publib.boulder.ibm.com/infocenter/wsmashin/v1r1/index.jsp?topic=/com.ibm.websphere.sMash.doc/using/zero.php/TypeConversion.html
