如何從json解碼中獲取嵌套的數組數據？

Question

我有一個需要在PHP中解析的JSON響應。 這是原始的JSON：

{
    "status": 200,
    "status_message": "Route Successfull",
    "data": [
        [
            ["Karachi Company", "33.690166", "73.030357", "1-C"],
            ["Peshawar Mor", "33.684509", "73.047585", "1-C"],
            ["Federal Government College", "33.671909", "73.056038", "1-C"],
            ["I\/9 Police Station", "33.660728", "73.064430", "1-C"],
            ["Pindora Chungi", "33.652046", "73.064301", "1-C"],
            ["Double Road", "33.655663", "73.070930", "110"], 14
        ],
        [
            ["Karachi Company", "33.690166", "73.030357", "115"],
            ["Bohar Masjid", "33.691372", "73.040985", "115"],

            ["Double Road", "33.655663", "73.070930", "110"], 32
        ],
        [
            ["Karachi Company", "33.690166", "73.030357", "120"],
            ["FSD", "33.697506", "73.035721", "120"],
            ["Tipu Market", "33.700459", "73.041435", "120"],

            ["G-6\/2", "33.717533", "73.082520", "120"],
            ["Melody", "33.714916", "73.084656", "120"],

            ["Abpara", "33.708942", "73.089142", "120"],
            ["MNA Hostel", "33.726662", "73.090408", "120"],
            ["National Convention Center", "33.712711", "73.103676", "120"],
            ["Rawal Lake", "33.721302", "73.134445", "120"],
            ["Kashmir Chowk", "33.708317", "73.105339", "110"],
            ["Masjid Stop", "33.705292", "73.106873", "110"],
            ["Golf Club", "33.702656", "73.108376", "110"],
            ["Rawal Dam", "33.689449", "73.110977", "110"],
            ["Margalla Town", "33.678829", "73.104057", "110"],
            ["Faizabad", "33.663212", "73.084801", "110"],
            ["Double Road", "33.655663", "73.070930", "110"], 39
        ]
    ]
}

我試着做

$result = json_decode($response);
$res = (array)$result[0]->data;
print_r($res);

但這似乎只顯示一個空數組。 我期望它是映射到data鍵的數組。 我應該怎么做才能得到這些數組？

Answer 1

使用JavaScript

您的JSON是一個javascript對象 ，您可以通過使用來獲取data鍵的值. (DOT) . (DOT) 。

答：1

var json = {}; // json data
var data=json.data; // now you can get any inner array with index.
var innerData=data[0];
var array=innerData[0]; //["Karachi Company", "33.690166", "73.030357", "1-C"]
console.log(array[0]); //Karachi Company

答：2

function printJSON(json){
    var data=json.data;
    for(var i=0;i<data.length;i++){
        var innerData=data[i];
        for(var j=0;j<innerData.length;j++){
            console.log(innerData[j]);
        }
    }
}
