Question

我有一个json api提要，我想对其进行重组以用于Google折线图中，但是我不知道如何遍历json数据以在php中创建一个新数组。为了使事情复杂化，我要为每个项目绘制的数据位于不同的行上。

这是json数据

gitPullAll() {
    for branch in `git branch | sed -E 's/^\*/ /' | awk '{print $1}'`; do
        git checkout $branch
        git pull -p
        printf "\n"
    done
    echo "Done"
}

这是我要为折线图实现的结构...

        }
    ]
}

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。任何帮助表示赞赏！

您可以在json上循环两次-首先在数组上获取所需的数据并将其格式化。

首先，将json循环为：

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

现在，在$data上再次循环以格式化输出格式：

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

$res将包含您的需求格式
