Question

我有一个JSON响应，我需要在PHP中解析。这是原始的JSON：

{
    "status": 200,
    "status_message": "Route Successfull",
    "data": [
        [
            ["Karachi Company", "33.690166", "73.030357", "1-C"],

        ]
    ]
}

我试过

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

但似乎只显示一个空数组。我原以为它是映射到data键的数组。我应该怎么做才能获得这些数组？

Answer 1

使用JavaScript

您的JSON是javascript object，data获得. (DOT)密钥值。

答案：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

答案：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]);
        }
    }
}

如何从json解码中获取嵌套数组数据？
