Question

大家好，我一直试图这样做。你能否告诉我如何解决这个问题。我有一个包含问题的文本文件，以及每个元素之间使用空格键间隔的各自的多项选择答案。我已经能够读取文本文件行并将其放入数组中。但是现在很难实现的是如何将每个元素放到一个html表单元素中。这些是我的代码：

文字档案：

编号问题（a）（b）（c）（d） 1螺旋模型最重要的特征是需求分析。风险管理。质量管理。配置管理。 2最差的耦合类型是数据耦合。控制耦合。邮票联轴器。内容耦合。 3故障基础测试技术之一是单元测试。 beta测试。压力测试。突变检测。 4故障模拟测试技术是突变测试压力测试黑盒测试白盒测试 5 RS也被称为白盒测试规范压力测试综合测试黑盒测试

读取文本文件的页面：

`html>
<head>
<title>read</title>
</head>
<body>
<b><u> QUESTIONS AND ANSWERS QUIZ</u></b <br /> 
<p>
<?php
$openFile = fopen("questionandanswers.txt", "r") or exit ("unable to open the text       file");
$fileContents = fread($openFile, filesize("questionandanswers.txt"));
fclose($openFile);
$delimiter = "  ";
$myArray = explode($delimiter, $fileContents);
print_r($myArray);
?>
</p>
</body>
</html>`

print_r显示以下内容：

数组（[0] =＆gt;数字[1] =＆gt;问题[2] =＆gt;（a）[3] =＆gt;（b）[4] =＆gt;（c）[5] = ＆gt;（d）1 [6] =＆gt;螺旋模型最重要的特征是需求分析。[7] =＆gt;风险管理。[8] =＆gt;质量管理。[9] =＆gt;配置管理。 2 [10] =＆gt;最差类型的耦合是[11] =＆gt;数据耦合。[12] =＆gt;控制耦合。[13] =＆gt;标记耦合。[14] =＆gt;内容耦合.3 [15] =＆gt;故障基础测试技术之一是[16] =＆gt;单元测试。[17] =＆gt; beta测试。[18] =＆gt;压力测试。[19] =＆gt;突变测试。 4 [20] =＆gt;故障模拟测试技术是[21] =＆gt;突变测试[22] =＆gt;压力测试[23] =＆gt;黑盒测试[24] =＆gt;白盒测试5 [25] ] =＆gt; RS也被称为[26] =＆gt;白盒测试[27] =＆gt;压力测试[28] =＆gt;综合测试[29] =＆gt;黑盒测试）

Answer 1

您应该将数组格式化为多维数组，其中索引0是问题：

Array
(
    [0] = array
    (
        [0] = "This is the first question";
        [1] = "Answer A";
        [2] = "Answer B";
    )
    [1] = array
    (
        [0] = "This is the second question";
        [1] = "Answer A";
        [2] = "Answer B";
        [3] = "Answer C";
    )
)

现在可以通过以下方式添加它：

<form>
    <?php
        foreach($filecontent as $question)
        {
            echo '<p>' .$question[0] .'</p>';
            for($i = 1; $i < count($question); $i++)
            {
                echo '<input value="' .$question[$i] .'" />';
            }
        }
    ?>
</form>

Answer 2

你explode()使用空格作为分隔符，这就是你将每个单词作为数组元素的原因。 explode()只使用你给它的字符，并在遇到字符时分割字符串。

您的数据（文件）没有模式。因此，您需要在文本中建立一些规则，否则您将无法分离所需的信息：

我修改了你的文字，建立了一些规则：

问题将以冒号（:)结束。
答案将以点（。）结束，所有这些都是最后一个，因为我们将使用问题的编号作为分隔符。
问题或答案不包含任何数字[0-9]，否则会混淆正则表达式。

这是我手动修改以使文本有效的结果文本：

$string = 'Number Question (a) (b) (c) (d) 1 The most important feature of spiral model is: requirement analysis. risk management. quality management. configuration management 2 The worst type of coupling is: Data coupling. control coupling. stamp coupling. content coupling 3 One of the fault base testing techniques is: unit testing. beta testing. Stress testing. mutation testing 4 A fault simulation testing technique is: Mutation testing. Stress testing. Black box testing. White box testing 5 RS is also known as: specification of White box testing. Stress testing. Integrated testing. Black box testing';

解决方案：之后我们可以使用一些代码来分离信息：

<html>
    <head>
    <title>read</title>
    </head>
    <body>
        <b><u> QUESTIONS AND ANSWERS QUIZ</u></b> <br />
<?php
$openFile = fopen("questionandanswers.txt", "r") or exit ("unable to open the text       file");
$string = fread($openFile, filesize("questionandanswers.txt"));

//Regex to get from the first number to the string's end, so we ignore the Number Question... bit;
preg_match('/\d.*/', $string, $match);

//We get all the strings starting with a number until it finds another number (which will be the beginning of another question;
preg_match_all('/\d\D*/', $match[0], $results);

$qas = array(); // We prepare an array with all the questions/answers
foreach($results[0] as $result){
    //Separating the answer from the string with all the answers.
    list($question, $all_answers) = explode(':', $result);

    //Separating the different answers
    $answers_array = explode('.', $all_answers);

    //Stuffing the question and the array with all the answers into the previously prepared array;
    $qas[] = array('question' => $question, 'answers' => $answers_array);
}

//Looping through the array and outputting all the info into a form;
foreach($qas as $k => $v){
    echo "<label>{$v['question']}</label><br/>";
    echo "<select>";

    //we loop through $v['answers'] because its an array within the array with all the answers.
    foreach($v['answers'] as $answer){
        echo "<option>$answer</option>";//the output
    }
    echo "</select>";
    echo "<br/><br/>";
}

?>
    </body>
</html>

由于所有评论看起来很复杂，实际上它们不到20行文本
