从 Multidem 数组中提取数据

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（如下所示）

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。

所有或部分数据的每次尝试都失败了。我一直无法获得第 3 个嵌套数据，即名字、中间名和姓氏。

如何获取像这样的大型 multidem 数组，并在 foreach 循环中提取上面列出的数据，以便将其导入数据库？我觉得它比我做的要简单得多。我没有包含任何代码，因为我还没有任何看起来非常有用的东西。

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 是可变长度的，那么你需要循环它或implode(', ', $data['schools'])。
