我怎样在一个数组引用添加到Perl中的现有阵列的中间？ [英] How do I add an array ref to the middle of an existing array in Perl?

问题描述

欲能够阵列放置到数组。例如，我可能有一个这样的数组：

I want to be able to place an array into an array. For example, I may have an array like this:

my @array1 = ("element 1","element 2","element 3");

然后我有另一个数组

Then I have another array

my $array_ref = ["this will", "go between", "element 1 and 2"];

欲放置 $ ARRAY_REF 到第一，使得第一阵列
看起来是这样的：

I want to place $array_ref into the first so that the first array looks like this:

("element 1",["this will", "go between", "element 1 and 2"],"element 2","element 3")

我似乎无法做到这一点。我看了看遍谷歌和什么也没找到。

I can't seem to do this. I looked all over Google and found nothing.

推荐答案

所以，你使用剪接以取代0你所需元素与元素1（第二个元素，第一个元素是0）开头的元素：

So you use splice to replace 0 elements beginning with element 1 (the second element, the first is element 0) with your desired elements:

splice( @array, 1, 0, ["this will", "go between", "element 1 and 2"] );

或者可能你的意思是：

Or possibly you mean:

splice( @array, 1, 0, "this will", "go between", "element 1 and 2" );

如果你不想嵌套数组。
