Php 从mysql打印数据时循环中的循环

我想创建一个简单的投票系统。我有两个问题和两个答案。第一个问题有两个答案，但第二个问题没有答案。从某种意义上说，我想得到：

First question?
Answer1
Answer2

Second question?

但是我越来越

First question?
Answer1
Answer2

Second question?
Answer1 
Answer2

第二个问题不需要有答案1和答案2（与第一个问题的答案相同，但我在mysql中有两个答案）

我的foreach循环。。我需要如何更改循环

foreach($questions->getQuestion($_GET["category"]) as $data) // Questions
{
    echo $data["question"] . "<br/>";
    foreach($questions->getAnswer($data["id"]) as $answers) // Answers
    {
        echo $answers["answer"] . "<br/>"; // This needn't print data to below of Second Question
    }
}

数据：

  Array
(
    [0] => Array
        (
            [id] => 1
            [soru] => First Question
            [kategori] => 1
        )

    [1] => Array
        (
            [id] => 2
            [soru] => Second Question
            [kategori] => 1
        )

)
Array
(
    [0] => Array
        (
            [id] => 1
            [soru] => First Question
            [kategori] => 1
        )

    [1] => Array
        (
            [id] => 2
            [soru] => Second Question
            [kategori] => 1
        )

    [2] => Array
        (
            [id] => 1
            [cevap] => Answer1
            [sorular] => 1
        )

    [3] => Array
        (
            [id] => 2
            [cevap] => Answer2
            [sorular] => 1
        )

    [4] => Array
        (
            [id] => 1
            [cevap] => Answer1
            [sorular] => 1
        )

    [5] => Array
        (
            [id] => 2
            [cevap] => Answer2
            [sorular] => 1
        )

注：这些数据仅为示例。这些是mysql中的数据。

我能想到的最简单的方法是有两个查询：

按

question\u id

请求丢失列表1中所有问题的所有答案。按问题编号排序

然后在php方面，匹配每个问题的答案。这将是一个单循环，因为问题和答案都已排序，不需要“后退”

最终的结果将是这样一个结构：

list = [
    {
       question: "Lorem ipsum",
       answers: [
          "answer number one",
          "answer number two"
       ]
    },
    {
       question: "Cogito ergo sum",
       answers: [
          "answer number one",
          "answer number two"
          "answer number three",
          "answer number four"
       ]
    }
]

您应该避免单独向DB查询每个问题的答案。这有点浪费。

@tereško现在？你能理解吗？你的示例代码看起来不错。。如果一个问题没有答案，它们就不会显示出来。你有什么问题？您是否要求人们编写getQuestion和getAnswer方法？@Birlikisgu，那么您必须更改“SQL代码”。否则就没有意义了。@Birlikisgu，没有什么可看的，只需重写SQL，使问题查询

连接
s问题，对于类别中的所有问题，按
question\u id
排序。或者更好——制定一个方法
getQuestions（$cat）
。如果你不会写作，那就雇佣一个会写的人。StackOverflow不是免费的代码生成器。
list = [
    {
       question: "Lorem ipsum",
       answers: [
          "answer number one",
          "answer number two"
       ]
    },
    {
       question: "Cogito ergo sum",
       answers: [
          "answer number one",
          "answer number two"
          "answer number three",
          "answer number four"
