PHP测验-显示正确和不正确的答案

我有一个php测试脚本，我一直在使用，并试图修改它，以显示正确和不正确的答案，我有问题试图完成这一点

因此，当用户选择错误答案时，我希望脚本显示错误答案，然后在下面显示正确答案。我已经弄清楚了如何显示正确答案的字母，但我希望显示的是实际答案，而不仅仅是字母

我是一个php初学者，因此任何帮助都将不胜感激

以下是完整的代码：

<?php get_header();

/*
Template Name: PHP Quiz safety asmnt
*/


$Questions = array(
    1 => array(
        'Question' => 'The appropriate response during a health threatening emergency such as a fire or toxic spill is to:',
        'Answers' => array(
            'A' => 'Pull the fire alarm; evacuate immediately to the assemply point; and do not re-enter the cleanroom until instructed to do so.',
            'B' => 'Notify lab; evacuate immediately to the assemply point; and do not re-enter the cleanroom until instructed to do so.',
            'C' => 'Call EH&S'
        ),
        'CorrectAnswer' => 'A'
    ),
    2 => array(
        'Question' => 'With proper use of wet bench and disposal procedures, the laboratory should be free of odors. In general, if you smell something, you should:',
        'Answers' => array(
            'A' => 'Call EH&S; Clear affected area if necessary; Notify staff and other users',
            'B' => 'Do nothing; odd smells are normal when working in the cleanroom.',
            'C' => 'Notify staff member; clear affected area; wait for instruction from staff who will investigate'
        ),
        'CorrectAnswer' => 'C'
    )
);

 <div id="bodyPage" class="clear">

<?php 

if (isset($_POST['answers'])){
    $Answers = $_POST['answers']; // Get submitted answers.
    echo '<br />';

    // Automated question checking!)

    foreach ($Questions as $QuestionNo => $Value){
        // Echo the question
         echo $QuestionNo. '.&nbsp;&nbsp;' .$Value['Question'].'<blockquote>';

        if ($Answers[$QuestionNo] != $Value['CorrectAnswer']){

        } else {

        }
        echo '</blockquote>';

    }

    } else {

    <form action="<?php the_permalink(); ?>" method="post" id="quiz">

    <ol>
    <?php foreach ($Questions as $QuestionNo => $Value){ ?>

    <li>
        <h4><?php echo $Value['Question']; ?></h4>
        <?php 
            foreach ($Value['Answers'] as $Letter => $Answer){ 
            $Label = 'question-'.$QuestionNo.'-answers-'.$Letter;
        ?>
        <div>
            <input type="radio" name="answers[<?php echo $QuestionNo; ?>]" id="<?php echo $Label; ?>" value="<?php echo $Letter; ?>" />

<?php

<!------- end body ------->
</div>
<?php get_footer(); ?>

有点晚了，但有一个办法：

    foreach ($Questions as $QuestionNo => $Value){
    // Echo the question
    echo $Value['Question'].'<br />';

    if ($Answers[$QuestionNo] != $Value['CorrectAnswer']){
        echo '<span style="color: red;">'.$Value['Answers'][$Answers[$QuestionNo]].'</span>'; // Replace style with a class
    } else {
        echo '<span style="color: green;">'.$Value['Answers'][$Answers[$QuestionNo]].'</span>'; // Replace style with a class
    }
    echo '<br /><hr>';
}

foreach（$Questions as$QuestionNo=>$Value）{
//附和这个问题
echo$Value['Question']。
；
如果（$Answers[$QuestionNo]！=$Value['CorrectAnswer']）{
回显“”。$Value['Answers'][$Answers[$QuestionNo].'；//用类替换样式
}否则{
回显“”。$Value['Answers'][$Answers[$QuestionNo].'；//用类替换样式
}
回声“
”；
}

（摘自：）
试试这个：

foreach( $Questions as $QuestionNo => $Value ) {
    echo $QuestionNo . '. ' . $Value['Question'].'<blockquote>';

    if( $Answers[$QuestionNo] != $Value['CorrectAnswer'] ) {
        echo 'You entered incorrectly:<br />'.'<span style="color:red;">'.$Value['Answers'][$Answers[$QuestionNo]].'</span>';
        echo '<br/>'.'The correct answer is:<br />'.'<span style="color: green;">'.$Value['Answers'][$Answers[$QuestionNo]].'</span>';
    } else {
        echo 'You entered correctly:<br />'.'<span style="color: green;">'.$Value['Answers'][$Answers[$QuestionNo]].'</span>';
    }
    echo '</blockquote>';
}

foreach（$Questions as$QuestionNo=>$Value）{
回显$QuestionNo.'.$Value['Question'].'；
如果（$Answers[$QuestionNo]！=$Value['CorrectAnswer']）{
echo“您输入错误：
”。$Value['Answers'][$Answers[$QuestionNo].'；
回显“
”。“正确答案是：
”。$Value['Answers'][$Answers[$QuestionNo].”；
}否则{
echo“您输入正确：
”。$Value['Answers'][$Answers[$QuestionNo].'；
}
回声'；
}
