我正在使用一系列员工数据，我将其转换为JSON并将其传递给插件以创建组织结构图。组织结构图有多个级别，我的目标是对这些级别进行颜色编码以显示不同的组织。
我的数组已嵌套，并且包含manager和children。
我试图找出如何循环遍历此数组并为不同级别指定颜色。
例如，数组的第一级是蓝色，下一级是红色等等。我需要做的是为class添加一个键，然后添加它的值为levelx（其中x是深度的水平数）。
这里的最终目标是能够弄清楚如何在同一级别的所有记录上添加相同的键/值。
以下是播放class key的数组示例。
是否有任何PHP函数可以在嵌套数组中确定其级别，这将使这更容易？

我会创建一个递归遍历数组的函数：
function setLevel(&$arr, $level)
{
foreach ($arr as &$element) {
$element['class'] = 'level-' . $level;
setLevel($element['children'], $level + 1);
}
}
setLevel($arr, 1);
