PHP:数组的区别;多维数组和二次数组键

I am trying to sort out a multidimensional array based on an array of keys (query params), but am having no luck in doing so.

我正在尝试根据一组键(查询参数)对一个多维数组进行排序，但是这样做没有运气。

Array From DB:

从DB数组:

AOD (Array, 2 elements)
  topic (String, 21 characters ) Alcohol & Other Drugs
  lessons (Array, 29 elements)
CEH (Array, 2 elements)
  topic (String, 25 characters ) Community & Environmental
  lessons (Array, 23 elements)

Array of Keys (Query String):

键的数组(查询字符串):

0 (String, 3 characters ) AOD
1 (String, 3 characters ) CEH

So, if I only passed in AOD, then the first array above would only return the multi-dimensional array of AOD

所以，如果我只在AOD中传递，那么上面的第一个数组只会返回AOD的多维数组。

代码:

array_intersect($snsData, array_flip($query_topics))

Working Code:

工作代码:

array_intersect_key($snsData, array_flip($query_topics))

Where $query_topics is an array of $_GET params

$query_topic是$_GET params的数组
