如何将数组键关联到特定的先前键？

Question

我目前有一个存储大量问题、问题类型和答案的数组。现在答案可以有不同的长度。例如：

  0 => array:222 [▼
    0 => "(Type): multiplechoice"
    1 => "(Question): Which of the following is true about pre-test imagery?"
    2 => "(A): People with a cranial fault can visualize the muscle being strong and make it go strong, while people without a cranial faults cannot."
    3 => "(B): If Governing Vessel (GV) 20 tests weak, it also means they have a cranial fault. This is on the midline at the apex of the head."
    4 => "(C): The three most common cranial faults are TMJ, occiput and sphenoid"
    5 => "(D): All of the above"
    6 => "(Correct): D"
    7 => "(Type): multiplechoice"
    8 => "(Question): Which of the following is not true about the TMJ?"
    9 => "(A): Every single TMJ nerve pathway goes through the mesencephalon in the midbrain."
    10 => "(B): When you work on the TMJ it is a neurological back-up for the entire body."
    11 => "(C): To correct press on the glabella with one hand as you press of the back of the head with the other as the patient touches the chin with two fingers and breathes in only one time."
    12 => "(Correct): C"
    13 => "(Type): truefalse"
    14 => "(Question): To test for a deficiency of the four primary neurotransmitters, point the edge of a magnet straight in at each of the four corresponding cranial bon ▶"
    15 => "(A): True"
    16 => "(B): False"
    17 => "(Correct): A"

我面临的问题是每个问题都包含一个question、type 和correct 值，但答案的数量可能不同 - 可能有 10 多个答案。

我目前的方法是遍历数组并为问题、类型和更正创建新数组，然后循环遍历数组并通过键配对问题的值。由于存在不同数量的答案，不幸的是，这并没有带来好处。

有什么可能的方法来解决这个问题？如何将所有值与适当的问题相关联？

非常感谢您的帮助和提示！

也许你可以把这样的问题分组？

$arr = array(
0 => "(Type): multiplechoice",
1 => "(Question): Which of the following is true about pre-test imagery?",
2 => "(A): People with a cranial fault can visualize the muscle being strong and make it go strong, while people without a cranial faults cannot.",
3 => "(B): If Governing Vessel (GV) 20 tests weak, it also means they have a cranial fault. This is on the midline at the apex of the head.",
4 => "(C): The three most common cranial faults are TMJ, occiput and sphenoid",
5 => "(D): All of the above",
6 => "(Correct): D",
7 => "(Type): multiplechoice",
8 => "(Question): Which of the following is not true about the TMJ?",
9 => "(A): Every single TMJ nerve pathway goes through the mesencephalon in the midbrain.",
10 => "(B): When you work on the TMJ it is a neurological back-up for the entire body.",
11 => "(C): To correct press on the glabella with one hand as you press of the back of the head with the other as the patient touches the chin with two fingers and breathes in only one time.",
12 => "(Correct): C",
13 => "(Type): truefalse",
14 => "(Question): To test for a deficiency of the four primary neurotransmitters, point the edge of a magnet straight in at each of the four corresponding cranial bon ▶",
15 => "(A): True",
16 => "(B): False",
17 => "(Correct): A");


$j=-1;
$res = array();
Foreach($arr as $value){
    If(substr($value,0,6)== "(Type)"){
        $j++;
    }
    preg_match("/\((.*?)\): (.*)/", $value, $match);
    $res[$j][$match[1]]= $match[2];

}

Var_dump($res);

编辑删除一个正则表达式。 然而，根据 3v4l 的变化，系统时间已从 0.003 秒变为 0.040 秒。
你是法官克里斯，有些人发誓正则表达式会在不知道或不尝试的情况下放慢速度。
