Question

所以基本上我遇到了一个问题，我有一个以下面给出的格式的数组。我想使用这些数据创建一个highcharts折线图。

一切正常，只是因为我无法将此JSON转换为高级图表识别的JSON。

{
    name: [
        1000,
        1001
    ],
    data: [
        {
            January: "7",
            February: "4",
            March: "1",
            April: "0",
            May: "0",
            June: "1",
            July: "3",
            August: "6",
            September: "2",
            October: "2",
            November: "8",
            December: "7"
        },
        {
            January: "6",
            February: "10",
            March: "1",
            April: "1",
            May: "0",
            June: "0",
            July: "0",
            August: "2",
            September: "3",
            October: "2",
            November: "2",
            December: "5"
        }
    ]
}

Highcharts支持JSON

我想将此数组转换为如下结构：

[
      {
         name: '1000',
         data: [7,4,1,0,0,1,3,6,2,2,8,7]
     }, {
         name: '1001',
         data: [6,10,1,1,0,0,0,2,3,2, 2,5]
     }
]

Answer 1

使用foreach遍历其中一个属性，并使用该元素和另一个属性中相应元素的值构建关联数组。

$result = array();
foreach ($input['name'] as $i => $name) {
    $result[] = array('name' => $name, 'data' => array_map('intval', array_values($input['data'][$i])));
}

<?php  

$json_res = json_decode('{
    "name": [
        1000,
        1001
    ],
    "data": [
        {
            "January": "7",
            "February": "4",
            "March": "1",
            "April": "0",
            "May": "0",
            "June": "1",
            "July": "3",
            "August": "6",
            "September": "2",
            "October": "2",
            "November": "8",
            "December": "7"
        },
        {
            "January" :"6",
            "February" :"10",
            "March" :"1",
            "April" :"1",
            "May" :"0",
            "June" :"0",
            "July" :"0",
            "August" :"2",
            "September" :"3",
            "October" :"2",
            "November" :"2",
            "December" :"5"
        }
    ]
}',true);  

$result = array();
foreach ($json_res['name'] as $key => $val) {

    $result[] = array('name' => $val, 'data' => array_values($json_res['data'][$key]));

}

echo json_encode($result);exit;
#echo '<pre>'; print_r($result); 
# answer the way you want
//[{"name":1000,"data":["7","4","1","0","0","1","3","6","2","2","8","7"]},{"name":1001,"data":["6","10","1","1","0","0","0","2","3","2","2","5"]}]
?>
