Php Laravel CSV文件读取角度作为前端

大家好

我有一个CSV文件，其中包括：

1.453453,4.578413,0.314132,0.764312,0.123422 2.453453,3.578413,0.764312,0.314132,0.123422 3.453453,2.578413,0.123422,0.764312,0.314132 4.453453,1.578413,0.314132,0.123422,0.764312

要在《邮递员》中阅读此内容，以下是我的代码：

    $keys = ['PGA', 'PGV', 'X-Axis', 'Y-Axis', 'Z-Axis'];
    $json = [];
    $path = Storage::path('upload/test.txt');
    $file = fopen($path, 'r');
    while (($line = fgetcsv($file)) !== false) {
         $json[] = array_combine($keys, $line);
    }
    fclose($file);
    return json_encode($json);

输出为：

[
    {
        "PGA": "1.453453",
        "PGV": "4.578413",
        "X-Axis": "0.314132",
        "Y-Axis": "0.764312",
        "Z-Axis": "0.123422"
    },
    {
        "PGA": "2.453453",
        "PGV": "3.578413",
        "X-Axis": "0.764312",
        "Y-Axis": "0.314132",
        "Z-Axis": "0.123422"
    },
    {
        "PGA": "3.453453",
        "PGV": "2.578413",
        "X-Axis": "0.123422",
        "Y-Axis": "0.764312",
        "Z-Axis": "0.314132"
    },
    {
        "PGA": "4.453453",
        "PGV": "1.578413",
        "X-Axis": "0.314132",
        "Y-Axis": "0.123422",
        "Z-Axis": "0.764312"
    }
]

但是我需要在数据之前添加'data:'，并在另一个

{}

中： 像这样：

{    
  "data":  [
        {
            "PGA": "1.453453",
            "PGV": "4.578413",
            "X-Axis": "0.314132",
            "Y-Axis": "0.764312",
            "Z-Axis": "0.123422"
        },
        {
            "PGA": "2.453453",
            "PGV": "3.578413",
            "X-Axis": "0.764312",
            "Y-Axis": "0.314132",
            "Z-Axis": "0.123422"
        },
        {
            "PGA": "3.453453",
            "PGV": "2.578413",
            "X-Axis": "0.123422",
            "Y-Axis": "0.764312",
            "Z-Axis": "0.314132"
        },
        {
            "PGA": "4.453453",
            "PGV": "1.578413",
            "X-Axis": "0.314132",
            "Y-Axis": "0.123422",
            "Z-Axis": "0.764312"
        }
    ]
}

我使用的角度作为我的前端，我需要这是显示。因此，我需要补充上述内容。谢谢你给我的每一个帮助！我必须把“数据”放在网页里面

谢谢 $keys = ['PGA', 'PGV', 'X-Axis', 'Y-Axis', 'Z-Axis']; $json = []; $path = Storage::path('upload/test.txt'); $file = fopen($path, 'r'); while (($line = fgetcsv($file)) !== false) { $json[] = array_combine($keys, $line); } fclose($file); $modified = ["data" => $json]; return json_encode($modified);
