如何将php中接收到的字符串转换为json数组并循环使用 - how to convert the string received in php to json array and loop through it?

how to convert the string received in php to json array and loop through it?

我正在发送一个json数组，该数组使用android中的StringEntity类转换为String。我在php中收到一个类似下面的字符串。

   {
    "introduceesJson": [
        {
            "infoName": "Aa",
            "direction": "2",
            "version": "1",
            "infoNumber": "96 35 874125"
        },
        [
            {
                "infoName": "Aa",
                "direction": "2",
                "version": "1",
                "infoNumber": "96 35 874125"
            }
        ]
    ]
}

现在，我想把它转换成json数组并循环使用。伙计们，请帮帮我。任何帮助都将不胜感激。

try {
            JSONArray arr = new JSONArray("Your_String");
            for (int i=0;i<arr.length();i++) {
                JSONObject object = arr.getJSONObject(i);
                String data = object.getString("Your_key");
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

试试这个。

 $a='  {
        "introduceesJson": [
            {
                "infoName": "Aa",
                "direction": "2",
                "version": "1",
                "infoNumber": "96 35 874125"
            },
            [
                {
                    "infoName": "Aa",
                    "direction": "2",
                    "version": "1",
                    "infoNumber": "96 35 874125"
                }
            ]
        ]
    }';
    $res=json_decode($a,true);
    $data=array();
    $data=$res['introduceesJson'];
    echo sizeof($data);
