How to merge arrays in PHP

This article mainly introduces how PHP implements the merger of two arrays, and the value of one array is the subscript, and the value of the other array is the corresponding value.

PHP merges ordinary arrays, I believe everyone has mastered it. But for novice friends, when merging two arrays, the subscript and value of the new array are the values ​​of the two arrays before merging respectively.

<?php
$arr = [&#39;姓名&#39;,&#39;年龄&#39;,&#39;性别&#39; ];
$arr2 = [&#39;王小二&#39;,24,&#39;男&#39;];

var_dump(array_combine($arr,$arr2));
