下面显示了当前的布局和布局方式：

当前输出的代码是这样的：

 < table border ='1'id ='penaltytbl'> 
< thead> 
< tr> 
  < / thead> 
< tbody> 
<？php 
 $ row_span = array_count_values（$ searchQuestionNo）; 
 $ prev_ques =''; 
 foreach（$ searchQuestionNo as $ key => $ questionNo）{
 
？> 
 
< tr class =questiontd> 
<？php 
 if（$ questionNo！= $ prev_ques）{
？> 
< td class =questionnumtd q<？php echo $ questionNo？> _qnumrowspan =<？php echo $ row_span [$ questionNo]？>> 
<？php echo $ questionNo？>< input type =hiddenname =numQuestionvalue =<？php echo $ questionNo？> /> 
< / td> 
<？php 
} 
？> 
< td class =answertd><？php echo implode（'，'，$ incorrect_ans [$ key]）;？>< / td> 
< / tr> 
<？php 
 $ prev_ques = $ questionNo; 
} 
？> 
< / tbody> 
< / table> 
  

解决方案

要将当前表结构更改为所需的表结构你需要修改每个< td class =questionnumtd> / code>和

（2）如何回应您的< td class =answertd> 的

最简单的是< td class =answertd> 。 Change

 < td class =answertd><？php echo implode（'，'，$ incorrect_ans [$键]）;？>< / TD> 
< / tr> 
  

至

 <？php 
 foreach（$ incorrect_ans [$ key] as $ answer）{？> 
< td class =answertd><？php echo $ answer？>< / td> 
< / tr> 
<？php 
} 
  

< ; td class =questionnumtd> rowspan 有点难度，因为在你当前的表结构&代码显示问题2有两行 $ incorrect_ans [$ key] 。使用下面的 foreach 循环，它根据所有的 $ incorrect_ans [$ key] 设置一个问题rowspan $ q_row_span [$ i] p>

  $ q_counter = 1; //计数器为$ row_span 
 $ i = key（$ row_span）; //获得第一个问题编号
 foreach（$ incorrect_ans as $ key => $ val）{
 if（$ q_counter == 1）{
 $ q_row_span [$ i] = count（ $ val）;} 
 else {
 $ q_row_span [$ i] + = count（$ val）;} 
 if（$ q_counter> = $ row_span [$ i]）{
 $ q_counter = 1; 
 $ i ++;} 
 else {
 $ q_counter ++; } 
}

 $ q_row_span [$ i] + = count（$ val）;} 
 if（$ q_counter> = $ row_span [$ i]）{
 $ q_counter = 1; 
 $ i ++;} 
 else {
 $ q_counter ++; } 
} 
 $ prev_ques ='';

< / td> 
 <？php 
} 
 
 foreach（$ incorrect_ans [$ key] as $ answer）{？>

< / table> 
  

请参阅此phpfiddle，其中显示了您的原始结构以及上述代码的新结构。 http://phpfiddle.org/main/code/z8e-74b

So lets say below are the correct and incorrect answers for each question:

Question Number: 1   Correct Answer(s) B     Incorrect Answers A C D
Question Number: 2   Correct Answer(s) A C   Incorrect Answers B D
Question Number: 3   Correct Answer(s) D     Incorrect Answers A B C

Below shows the current layout and the way it should be laid out:

The code for the current output is this:

<table border='1' id='penaltytbl'>
<thead>
<tr>
<th class='questionth'>Question No.</th>
<th class='answerth'>Incorrect Answer</th></tr>
</thead>
<tbody>
<?php
$row_span = array_count_values($searchQuestionNo);
$prev_ques = '';
foreach($searchQuestionNo as $key=>$questionNo){

?>

<tr class="questiontd">
    <?php
    if($questionNo != $prev_ques){
    ?>
    <td class="questionnumtd q<?php echo$questionNo?>_qnum" rowspan="<?php echo$row_span[$questionNo]?>">
    <?php echo$questionNo?><input type="hidden" name="numQuestion" value="<?php echo$questionNo?>" />
    </td>
    <?php
    }  
    ?>
<td class="answertd"><?php echo implode(',', $incorrect_ans[$key]);?></td>
</tr>
<?php
$prev_ques = $questionNo;
}
?>
</tbody>
</table>

解决方案

To change your current table structure to your desired table structure you need to modify-
(1) the rowspan in each your <td class="questionnumtd"> and
(2) how you echo your <td class="answertd">'s

The easiest is the <td class="answertd">. Change

    <td class="answertd"><?php echo implode(',', $incorrect_ans[$key]);?></td>
</tr>

to

    <?php
    foreach($incorrect_ans[$key] as $answer){ ?>
            <td class="answertd"><?php echo$answer?></td>
           </tr>
    <?php
    }

The <td class="questionnumtd"> rowspan is a little harder as in your current table structure & code you show that there is 2 rows of $incorrect_ans[$key] for question 2. Using the foreach loop below, it sets a question rowspan $q_row_span[$i] based off all the $incorrect_ans[$key]

$q_counter = 1;// counter for $row_span
$i = key($row_span);  // gets first question number
foreach ($incorrect_ans as $key => $val){
    if($q_counter == 1){
        $q_row_span[$i] = count($val);}
    else{
        $q_row_span[$i] += count($val);}
    if($q_counter >= $row_span[$i]){
        $q_counter = 1;
        $i++;}
    else{
        $q_counter++; }
}

---

Try -

<table border='1' id='penaltytbl'>
<thead>
<tr>
<th class='questionth'>Question No.</th>
<th class='answerth'>Incorrect Answer</th></tr>
</thead>
<tbody>
<?php
$row_span = array_count_values($searchQuestionNo);
    $q_counter = 1;// counter for $row_span
    $i = key($row_span);  // gets first question number
    foreach ($incorrect_ans as $key => $val){
        if($q_counter == 1){
            $q_row_span[$i] = count($val);}
        else{
            $q_row_span[$i] += count($val);}
        if($q_counter >= $row_span[$i]){
            $q_counter = 1;
            $i++;}
        else{
            $q_counter++; }
    }
$prev_ques = '';
foreach($searchQuestionNo as $key=>$questionNo){

?>

<tr class="questiontd">
    <?php
    if($questionNo != $prev_ques){
    ?>
    <td class="questionnumtd q<?php echo$questionNo?>_qnum" rowspan="<?php echo$q_row_span[$questionNo]?>">
    <?php echo$questionNo?><input type="hidden" name="numQuestion" value="<?php echo$questionNo?>" />
    </td>
    <?php
    }  

    foreach($incorrect_ans[$key] as $answer){ ?>
    <td class="answertd"><?php echo$answer?></td>
</tr>
<?php
    }
$prev_ques = $questionNo;
}
?>
</tbody>
</table>
