I have 2 small questions I need help on which deals with the code below:

echo "<table border='1' id='markstbl'>
      <tr>
      <th class='questionth'>Question No.</th>
      <th class='questionth'>Question</th>
      <th class='answerth'>Answer</th>
      <th class='answermarksth'>Marks per Answer</th>
      <th class='noofmarksth'>Total Marks</th>
      </tr>\n";
                $previous_question_id = null;
          foreach ($searchQuestionContent as $key=>$question) {
            if ($previous_question_id == $searchQuestionId[$key]) {
          $searchQuestionId[$key] = '';
          $question = '';
          $searchMarks[$key] = '';
      }else{
          $previous_question_id = $searchQuestionId[$key];
      }
        echo '<tr class="questiontd">'.PHP_EOL;
        echo '<td class="optiontypetd">'.htmlspecialchars($searchQuestionId[$key]).'</td>' . PHP_EOL;
        echo '<td>'.htmlspecialchars($question).'</td>' . PHP_EOL;
        echo '<td class="answertd">';
        echo $searchAnswer[$key];
        echo '</td>' ;
        echo '<td class="answermarkstd"><input class="individualMarks" name="answerMarks[]" id="individualtext" type="text" "/></td>' . PHP_EOL;
        echo '<td class="noofmarkstd">'.htmlspecialchars($searchMarks[$key]).'</td>' . PHP_EOL;
}      
        echo '</tr>';
        echo "</table>" . PHP_EOL;

Question 1: If you look at the table above, I have a a column where it will contain text inputs. Now each text input will belong to each answer in the “Answer” column. My question is that is the text input set up correctly with me including a [] in the name attribute to set up an array? Should I include [] and is there anything else I should include in the text input code?

Question 2: At the moment the code above makes the table look like this example in JSFIDDLE1. But I want the table to be displayed as this example JSFIDDLE2. As you can see the blank rows in the other table have been rowspan so that it looks like the question and the total marks looks like its in one cell. How can I get the table above to look like JSFIDDLE2?

UPDATE:

Below is the full code, I am still receiving undefined index whenver $rowspans[.... is used. Is the code below correct:

$assessment = $_SESSION['id'] . $sessionConcat;

$query = "SELECT q.SessionId, s.SessionName, q.QuestionId, q.QuestionContent, an.Answer, q.QuestionMarks 
FROM Session s 
INNER JOIN Question q ON s.SessionId = q.SessionId
JOIN Answer an ON q.QuestionId = an.QuestionId AND an.SessionId = q.SessionId
WHERE s.SessionName = ?
ORDER BY q.QuestionId, an.Answer
";

// prepare query
$stmt=$mysqli->prepare($query);
// You only need to call bind_param once
$stmt->bind_param("s", $assessment);
// execute query
$stmt->execute(); 


// This will hold the search results
$searchQuestionId = array();
$searchQuestionContent = array();
$searchAnswer = array();
$searchMarks = array();

// Fetch the results into an array

// get result and assign variables (prefix with db)
$stmt->bind_result($dbSessionId, $dbSessionName, $dbQuestionId, $dbQuestionContent, $dbAnswer, $dbQuestionMarks);
while ($stmt->fetch()) {
$searchQuestionId[] = $dbQuestionId;
$searchQuestionContent[] = $dbQuestionContent;
$searchAnswer[] = $dbAnswer;
$searchMarks[] = $dbQuestionMarks;
}   

?>

    Q1. Yes, you could even specify a name between the [].

    Q2. It seems that $searchQuestionId is filled before your loop, right? In that case you could use array_count_values to store the frequency of each ID and access that array during the loop:

    before your loop: $rowspans = array_count_values($searchQuestionId);

    access rowspan value during loop with: $rowspans[$searchQuestionId[$key]].

    You’ll have to remove the line $searchQuestionId[$key] = ''; or else you won’t be able to access the correct $rowspan key.

    Finally, you’ll have to set up some more if statements to skip the <td>s on certain rows.

    $previous_question_id = null;
$rowspans = array_count_values($searchQuestionId);
foreach ($searchQuestionContent as $key=>$question) {

    // removed logic, not necessary to set empty strings if you're skipping them

    echo '<tr class="questiontd">'.PHP_EOL;

    if ($previous_question_id != $searchQuestionId[$key]) {
        echo '<td class="optiontypetd" rowspan="'.$rowspans[$searchQuestionId[$key]].'">'.htmlspecialchars($searchQuestionId[$key]).'</td>' . PHP_EOL;
        echo '<td rowspan="'.$rowspans[$searchQuestionId[$key]].'">'.htmlspecialchars($question).'</td>' . PHP_EOL;
    }

    echo '<td class="answertd">';
    echo $searchAnswer[$key];
    echo '</td>' ;
    echo '<td class="answermarkstd"><input class="individualMarks" name="answerMarks[]" id="individualtext" type="text" "/></td>' . PHP_EOL;

    if ($previous_question_id != $searchQuestionId[$key]) {
        echo '<td class="noofmarkstd" rowspan="'.$rowspans[$searchQuestionId[$key]].'">'.htmlspecialchars($searchMarks[$key]).'</td>' . PHP_EOL;
    }

    // moved this to the end
    if ($previous_question_id != $searchQuestionId[$key]) {
        $previous_question_id = $searchQuestionId[$key];
    }
}
