<th class='questionth'>Question No.</th>
<th class='answerth'>Incorrect Answer</th></tr>

<?php
$row_span = array_count_values($searchQuestionNo);

現在のテーブル構造を目的のテーブル構造に変更するには、
(1)rowspanそれぞれの<td class="questionnumtd">と
(2) をエコーする方法を変更する必要があり<td class="answertd">ます

最も簡単なのは<td class="answertd">. 変化する

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

に

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

現在のテーブル構造とコードでは、質問 2 の行が 2 つあることが示されているため、これは少し難しくなります。以下のループを使用して、すべて<td class="questionnumtd"> rowspanに基づいて質問の行スパンを設定します。$incorrect_ans[$key]foreach$q_row_span[$i]$incorrect_ans[$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++; }
}

試す -

<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>

                   3);

$ques_ans = array();    //to store incorrect answers against ques no.

$q_occ_count = array_count_values($searchQuestionNo);
foreach($searchQuestionNo as $key => $questionNo)

    if ( ! array_key_exists($questionNo, $ques_ans))
    {
        if($q_occ_count[$questionNo] === 1) //if a ques has only one correct ans
