php - 如何合并 2 个关联数组

Question

我有多个动态创建的 HTML 输入的表单，这些数据是从我想使用该createMany()方法存储在数据库中的输入中收集的，但目前只有来自“答案”输入的数据存储在数据库中。

一段时间后，我意识到createMany()我需要将数据合并到一个数组中。但我不知道如何管理。如果有人可以帮助我，我将不胜感激。

你试过array_merge_recursive函数吗？https://www.php.net/manual/en/function.array-merge-recursive.php

更新。

你能试试这个吗？

foreach($arr['answers'] as $key => $value){
    $arr['answers'][$key]['value'] = $arr['answer_value'][$key]['value'];
    unset($arr['answer_value'][$key]['value']);
}
