交替合并两个数组 [英] Merge two arrays alternatively

问题描述

我想要的是efficient(无循环)方式以first element of the resulting array是first element of the first array，the second element of the resulting array是the second element of the second array(或者)...的方式合并数组的方式...

What I want is an efficient (without looping) way to merge arrays in the way that the first element of the resulting array is the first element of the first array, the second element of the resulting array is the second element of the second array (alternatively)... etc

示例:

$arr1 = array(1, 3, 5);
$arr2 = array(2, 4, 6);

$resultingArray = array(1, 2, 3, 4, 5, 6);

推荐答案

假定两个数组的长度相同.

assuming both arrays have the same length.

$arr1 = array(1, 3, 5);
$arr2 = array(2, 4, 6);

$new = array();
for ($i=0; $i<count($arr1); $i++) {
   $new[] = $arr1[$i];
   $new[] = $arr2[$i];
}
var_dump($new);
