我如何合并2个关联数组[重复]

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 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，我意识到对于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。

blade.php

<div class="row justify-content-center">   
    <div class="col-lg-8">
        <div class="card">
            <div class="card-body">
              <h3 class="card-title">Create Question</h3>
                  <hr class="m-t-0 m-b-40">
                   {!! Form::model(array(), ['route' => ['question.store', $questionnaire->id], 'role' => 'form', 'class' => 'form-material m-t-40']) !!}
                    <div class="row">
                        <div class="col-md-12 col-lg-12 col-xl-12">

阵列目标

array:4 [▼
      "_token" => "eRzBm87dqPbzOjN1I8k6lD1cttHhNbeEUL0HUTCQ"
      "question" => array:1 [▶]
      "answers" => array:2 [▼
        0 => array:1 [▼
          "answer" => "dasd"
        ]
        1 => array:1 [▼
          "answer" => "asda"
        ]
      ]
      "answer_value" => array:2 [▼
        0 => array:1 [▼
          "value" => "2"
        ]
        1 => array:1 [▼
          "value" => "3"
        ]
      ]
    ]


array:4 [▼
      "_token" => "eRzBm87dqPbzOjN1I8k6lD1cttHhNbeEUL0HUTCQ"
      "question" => array:1 [▶]

Answer 1

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

更新。

你可以试试这个吗？

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

Answer 2

目前的数组结构

array:4 [▼
      "_token" => "eRzBm87dqPbzOjN1I8k6lD1cttHhNbeEUL0HUTCQ"
      "question" => array:1 [▶]
      "answers" => array:2 [▼
        0 => array:1 [▼
          "answer" => "dasd"
        ]
        1 => array:1 [▼
          "answer" => "asda"
        ]
      ]
      "answer_value" => array:2 [▼
        0 => array:1 [▼
          "value" => "2"
        ]
        1 => array:1 [▼
          "value" => "3"
        ]
      ]
    ]

array_merge_recursive 函数的结果是：

array:4 [▼
      0 => array:1 [▼
        "answer" => "dasd"
      ]
      1 => array:1 [▼
        "answer" => "asda"
      ]
      2 => array:1 [▼
        "value" => "2"
      ]
      3 => array:1 [▼
        "value" => "3"
      ]
    ]

但我希望我的数组结构看起来像这里：

"answers" => array:2 [▼
        0 => array:1 [▼
          "answer" => "dasd",
          "value" => "2"
        ]
        1 => array:1 [▼
          "answer" => "asda",
          "value" => "3"
        ]
      ]
