Php 如何区分答案

下面我有一段代码，它结合了每个问题的每个答案：

// $questionNumber is simply n in value[n][]
// $answers is an array of value attributes from <input>s for this question

foreach ($_POST['value'] as $questionNumber => $answers) {
    // combine all the answers into a single string (e.g. ACE)
    $selected_answer = implode('', $answers);

    // continue onto inserting rows into the Answer and Questions tables
    // ...
}

但我实际上想把答案分开，这样它就会显示如下：

Question 1: Answer: A
Question 1: Answer: C
Question 1: Answer: E
Question 2: Answer: B
Question 2: Answer: D
Question 3: Answer: C

// $questionNumber is simply n in value[n][]
// $answers is an array of value attributes from <input>s for this question

foreach ($_POST['value'] as $questionNumber => $answers) {
    // combine all the answers into a single string (e.g. ACE)
    $selected_answer = $answers;

    // continue onto inserting rows into the Answer and Questions tables
    // ...
}

所以我的问题是，我需要在我的php中做什么更改，以便将它们分开

假设它如下所示：

Question 1: Answer: A
Question 1: Answer: C
Question 1: Answer: E
Question 2: Answer: B
Question 2: Answer: D
Question 3: Answer: C

// $questionNumber is simply n in value[n][]
// $answers is an array of value attributes from <input>s for this question

foreach ($_POST['value'] as $questionNumber => $answers) {
    // combine all the answers into a single string (e.g. ACE)
    $selected_answer = $answers;

    // continue onto inserting rows into the Answer and Questions tables
    // ...
}

/$questionNumber的值仅为n[n][]
//$answers是用于此问题的s的值属性数组
foreach（$_POST['value']作为$questionNumber=>$answers）{
//将所有答案组合成一个字符串（例如ACE）
$selected_answer=$answers；
//继续在答案和问题表中插入行
// ...
}

试试这个：

foreach ($_POST['value'] as $questionNumber => $answers) 
{
    foreach($answers as $a)
    {  
             echo "Question: $questionNumber Answer: $a";

    }
}

似乎循环中的循环将输出您想要的内容。如果您需要进一步的帮助，请在$\u POST上运行print\u r（），然后给我答案。

我可以简单地执行

$selected\u answer=$a？
