array_splice（）关联数组 [英] array_splice() for associative arrays

问题描述

说我有一个关联数组：

array(
  "color" => "red",
  "taste" => "sweet",
  "season" => "summer"
);

和我想介绍一个新的元素进去：

and I want to introduce a new element into it:

"texture" => "bumpy" 

背后的第二个项目，但preserving所有的数组键：

behind the 2nd item but preserving all the array keys:

array(
  "color" => "red",
  "taste" => "sweet",
  "texture" => "bumpy", 
  "season" => "summer"
);

有一个函数来做到这一点？ array_splice（） 不会削减它，它可以用数字键工作只要。

is there a function to do that? array_splice() won't cut it, it can work with numeric keys only.

推荐答案

我认为你需要做的手动：

I think you need to do that manually:

# Insert at offset 2
$offset = 2;
$newArray = array_slice($oldArray, 0, $offset, true) +
            array('texture' => 'bumpy') +
            array_slice($oldArray, $offset, NULL, true);
