I need a table in browser to look like
enter image description here
Question1 Question2 Question3
Answer1-1 Answer2-1 Answer3-1
Answer1-2 Answer2-2 Answer3-2
This is my code:
<table class="table">
<thead>
<tr>
<?php foreach ($DATA['question'] as $question): ?>
<th><?php echo htmlspecialchars($question->title); ?></th>
<?php endforeach; ?>
</tr>
</thead>
<tbody>
<tr>
<?php foreach ($DATA['question'] as $question): ?>
<td><?php for ($i=0,$j=count((array)$question->answer);$i<$j;$i++) {
echo htmlspecialchars($question->answer[$i]->answer);
}?></td>
<?php endforeach; ?>
</tr>
</tbody>
My problem is that I can not place Answer1-2 in the next row of table.
Any idea?
Thanks a lot

Answer 1

There are a few options how you can do this.
Generate each of your intended columns as a single element and place that in a cell.
Populate an array in the way you wish to display them
Create a for(i=0;i<maxAmountOfAnswers;i++) wrapping another foreach (questions) and populate the table row by row.
Use DataTables or other libraries that can read a json.
Think about why you want this though; semantically tables are intended to display one kind of data. Is there a good reason why you wouldn't just show 1 table per question, or tables at all?

Answer 2

Thanks a lot for your answer! It is my solutionn.
<table class="table">
<thead>
<tr>
<?php foreach ($DATA['question'] as $question): ?>
<th><?php echo htmlspecialchars($question->title); ?></th>
<?php endforeach; ?>
</tr>
</thead>
<tbody>
<tr>
<?php foreach ($DATA['question'] as $question): ?>
<td><?php for ($i=0,$j=count((array)$question->answer);$i<$j;$i++) {
echo htmlspecialchars($question->answer[$i]->answer);
echo "<br />";
}?></td>
<?php endforeach; ?>
</tr>
</tbody>
</table>
And what is looks like.
