我如何将array_intersect()与数组中的数组一起使用? [英] How would i use array_intersect() with the arrays in an array?

问题描述

我在一个特定的数组中有动态数量的数组.
我们将其称为特定数组: FatherArray

此 FatherArray 中具有动态数量的数组，例如，现在为: Child1Array ， Child2Array .下次调用它时，它的个数可能会多于或少于这两个Child(number)Arrays.

因此，我想将array_intersect()函数与 FatherArray 的数组(子级)作为参数一起使用，就像array_intersect(Child1Array，Child2Array)一样.
我不知道如何动态地执行此操作，也找不到任何有关它的帮助，将不胜感激

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

推荐答案

如果您的版本相当新(

If your version is reasonably new (v5.6):

array_intersect(...$FatherArray);

否则:

call_user_func_array('array_intersect', $FatherArray);
