指数在PHP数组推动元件和移动previous元

问题描述

这是我的数组。我想在索引3推的元件，并在同一时间移动至previous元件下。 请阅读第一它不是array_splice（）工作

This is my array. I want to push an element at index 3 and at the same time move the previous element to next. Please read first its not array_splice() work

array(6) {
  [0]=>
  string(1) "One_test"
  [1]=>
  string(1) "Two_test"
  [2]=>
  string(1) "Three_test"
  [3]=>
  string(1) "Four_test"
  [4]=>
  string(1) "Five_test"
  [5]=>
  string(1) "Six_test"
}

所以，我期望的输出是

So my desired output is

array(6) {
  [0]=>
  string(1) "One_test"
  [1]=>
  string(1) "Two_test"
  [2]=>
  string(1) "Three_test"
  [3]=>
  string(1) "Six_test"
  [4]=>
  string(1) "Four_test"
  [5]=>
  string(1) "Five_test"
}

所以看到我需要用 5 索引元素，然后替换 3 索引元素的移动previously 3 索引元素进入下一。最后，推元件（5）删除

So notice I need replace 3rd indexed element with 5th indexed element and then move previously 3rd indexed element into next. Finally the pushed element (5th) to remove

任何想法？

推荐答案

从欺骗启发：

我会做一个 array_pop（）和 array_slice（）阵列上：

$original = array( 'a', 'b', 'c', 'd', 'e' );
$new_one = array_pop($original);

array_splice( $original, 3, 0, $new_one );

我的解决方案

所以前：

array(6) {
  [0]=>
  string(8) "One_test"
  [1]=>
  string(8) "Two_test"
  [2]=>
  string(10) "Three_test"
  [3]=>
  string(9) "Four_test"
  [4]=>
  string(9) "Five_test"
  [5]=>
  string(8) "Six_test"
}

和之后：

array(6) {
  [0]=>
  string(8) "One_test"
  [1]=>
  string(8) "Two_test"
  [2]=>
  string(10) "Three_test"
  [3]=>
  string(8) "Six_test"
  [4]=>
  string(9) "Four_test"
  [5]=>
  string(9) "Five_test"
}
