我如何将array_intersect（）与数组中的数组一起使用？
I have a dynamic amount of arrays in a specific array.
Let's call this specific array: FatherArray
This FatherArray has a dynamic amount of arrays in it, right now for example: Child1Array,Child2Array. Next time it gets called it could have more or less than those 2 Child(number)Arrays.
So I want to use the function array_intersect() with the arrays (children) of FatherArray as parameters, so like array_intersect(Child1Array,Child2Array).
I don't have a clue how i could do this dynamically, neither could I find anything about it, any help would greatly be appreciated
我在特定数组中有一个动态数量的数组。
让我们调用这个特定的数组： FatherArray strong>
这个 FatherArray strong>中有一个动态数量的数组，例如： 的 Child1Array 强>， Child2Array strong>即可。 下次调用时它可能比那些2个子（数字）数组更多或更少。
我想使用函数array_intersect（）和 FatherArray strong>作为参数，所以像array_intersect（Child1Array，Child2Array）。
我不知道我怎么能动态地做到这一点，我也找不到任何关于它的东西，任何帮助都会很大 不胜感激 p>

If your version is reasonably new (v5.6):
array_intersect(...$FatherArray);
Otherwise:
call_user_func_array('array_intersect', $FatherArray);
