Php 如何将索引数组转换为关联数组

我有这样一个数组：

array:10 [
       1 => "1. What is the first question?"
       2 => "A. First answer"
       3 => "B. Second answer"
       4 => "C. Third answer"
       5 => "D. Forth answer"
       6 => "ANSWER: A"
       7 => "2. What is the second question? This question is of multiple lines and it can 
             go into 2 or 3 or 4 lines, but make sure you import it correctly."
       8 => "A. Yes, I got it"
       9 => "B. No, I can’t"
       10 => "ANSWER: A"
   ]

array:2[
      'questions' => [
           0 => [
             'question_text' => '1. What is the first question?',
             'options' => [
                            0 => 'A. First answer',
                            1 => 'B. Second answer',
                            2 => 'C. Third answer',
                            3 => 'D. Forth answer'
                           ],
             'answer' => 'ANSWER: A'
             ],
         1 => [
             'question_text' => '2. What is the second question? This question is of 
                                  multiple lines and it can go into 2 or 3 or 4 lines, but 
                                  make sure you import it correctly."',
             'options' => [
                            0 => 'A. Yes, I got it',
                            1 => 'B. No, I can’t',

                           ],
             'answer' => 'ANSWER: A'
             ],
       ]
 ]

我想实现这样的阵列：

array:10 [
       1 => "1. What is the first question?"
       2 => "A. First answer"
       3 => "B. Second answer"
       4 => "C. Third answer"
       5 => "D. Forth answer"
       6 => "ANSWER: A"
       7 => "2. What is the second question? This question is of multiple lines and it can 
             go into 2 or 3 or 4 lines, but make sure you import it correctly."
       8 => "A. Yes, I got it"
       9 => "B. No, I can’t"
       10 => "ANSWER: A"
   ]

array:2[
      'questions' => [
           0 => [
             'question_text' => '1. What is the first question?',
             'options' => [
                            0 => 'A. First answer',
                            1 => 'B. Second answer',
                            2 => 'C. Third answer',
                            3 => 'D. Forth answer'
                           ],
             'answer' => 'ANSWER: A'
             ],
         1 => [
             'question_text' => '2. What is the second question? This question is of 
                                  multiple lines and it can go into 2 or 3 or 4 lines, but 
                                  make sure you import it correctly."',
             'options' => [
                            0 => 'A. Yes, I got it',
                            1 => 'B. No, I can’t',

                           ],
             'answer' => 'ANSWER: A'
             ],
       ]
 ]

我想将此索引数组转换为多维数组。如何转换此数组？

它不会是这么大的意大利面代码，即使它不适合两行：

结果：

array(1) {
  ["questions"]=>
  array(2) {
    [0]=>
    array(3) {
      ["question_text"]=>
      string(30) "1. What is the first question?"
      ["options"]=>
      array(4) {
        [0]=>
        string(15) "A. First answer"
        [1]=>
        string(16) "B. Second answer"
        [2]=>
        string(15) "C. Third answer"
        [3]=>
        string(15) "D. Forth answer"
      }
      ["answer"]=>
      string(9) "ANSWER: A"
    }
    [1]=>
    array(3) {
      ["question_text"]=>
      string(158) "2. What is the second question? This question is of multiple lines and it can 
             go into 2 or 3 or 4 lines, but make sure you import it correctly."
      ["options"]=>
      array(2) {
        [0]=>
        string(16) "A. Yes, I got it"
        [1]=>
        string(16) "B. No, I can’t"
      }
      ["answer"]=>
      string(9) "ANSWER: A"
    }
  }
}

尽管如此，这当然是一项非常特殊的任务，我同意前一位发言者的观点，即阵列是不寻常地指定的。但是如果是这样的话，你必须遵守这些准则……

我不知道如何得到这个数组，但要转换它，你最终将编写只适用于一组特定数据的意大利面代码，你必须添加越来越多的逻辑来处理所有情况。我建议重新使用生成数组的方式，而不是在以后转换数组。基本上，我的主要功能是在数据库中插入.Docx文件。我有这种类型的.DOcx文件。所以我将Docx文件转换为数组@N@scode2704我们可以为您的输入添加一个特定的解决方案，但前提是您的数组格式在任何情况下都发生了更改，那么该解决方案将无法工作。请发布您尝试的代码。
