从Multidem阵列中提取数据

Question

我一直在尝试从一个大型多维数组中为每个学生提取以下数据（再次向下显示）

Data -> gender,
Data -> grade,
Data -> name -> first,
Data -> name -> last,
Data -> name -> middle,
Data -> student_number,
Data -> ID

我通过搜索尝试了各种选项，包括Slice，Splice和for循环。

所有尝试都遇到了所有或部分数据失败。我从来没有能够获得First，Middle和Last名称的第三个嵌套数据。

如何使用这样的大型多重阵列，并在foreach循环中提取上面列出的数据，以便将其导入数据库？我觉得它比我做的更简单。我没有包含任何代码，因为我还没有任何看起来有用的东西。

下面是一个示例数组。谢谢！

Answer 1

最简单的方法可能是提取嵌套的data数组并循环：

foreach(array_column($array['data'], 'data') as $data) {
    echo $data['gender'];
    echo $data['name']['first'];
}

如果schools是可变长度，那么您需要循环或implode(', ', $data['schools'])。
