Php 如何更改数据结构以用于google折线图

我有一个json api提要，我想重新构造它，以便在google折线图中使用，但我不知道如何循环json数据以在php中创建一个新数组。使事情复杂化的是，我想为每个项目绘制的数据位于不同的行上

这是json数据

{
    "records": [
        {
            "id": "2",
            "groupno": "1",

            "price": "£17.99"
        }
    ]
}

这是我想要为线图实现的结构

[
    ['Date time',                   'Boot buddy price',     'Amazon echo price'],
    ['2019-04-14 16:00:29.595',     £14.99,                 £19.99],
    ['2019-04-14 21:50:31.362',     £14.99,                 £19.99],
    ['2019-04-14 21:54:11.184',     £12.99,                 £17.99],
]

我真的不知道从哪里开始。我发现的其他问题/解决方案没有相同的原始数据格式。感谢您的帮助

您可以在json上循环两次-首先在数组中获取所需的数据并格式化它们

首先，在json上循环如下：

$arr = jsone_decode($jsonStr, true);
foreach($arr as $e) {
    $data[$e["date"]][$e["name"]] = $e["price"];
}

现在，再次在

$data

上循环以格式化输出：

$res[] = ['Date time', 'Boot buddy price', 'Amazon echo price']; // set the header
foreach($data as $k => $e) {
    $res[] = [$k, $e["Boot buddy"], $e["Amazon echo"]];
}

而

$res

将包含您想要的格式

将包含您的愿望格式

您能解释一下您的愿望输出吗？是字符串还是数据？在本例中，您有6个元素，但输出5？如果您可以将现有数据放入google的数据表中，那么您可以使用google的数据视图和分组方法来获得所需的结果。请看一个类似的例子…@dWinder抱歉，我不清楚，我已经更新了这个例子，以清楚地显示所需的输出您能解释一下您所需的输出吗？是字符串还是数据？在本例中，您有6个元素，但输出5？如果您可以将现有数据放入google的数据表中，那么您可以使用google的数据视图和分组方法来获得所需的结果。请参阅类似示例…@dWinder抱歉，我不清楚，我已更新示例以清楚显示所需的输出
