Question

我有一个日期数组，类似下面的

Array
(
    [0] => stdClass Object
      (
        [question_id] => 64
        [title] => Question1
        [question_type_id] => 1
        [settings] => 
        [poll_id] => 5
        [answer] => Array
            (
                [0] => stdClass Object
                    (
                        [answer_id] => 1
                        [poll_id] => 5
                        [question_id] => 64
                        [answer] => Answer1-1
                        [created_at] => 2018-07-08 17:36:15
                    )

                [1] => stdClass Object
                    (
                        [answer_id] => 5
                        [poll_id] => 5
                        [question_id] => 64
                        [answer] => Answer1-2
                        [created_at] => 2018-07-08 19:27:33
                    )

            )

    )

[1] => stdClass Object
    (
        [question_id] => 65
        [title] => Question2
        [question_type_id] => 6
        [settings] => ["više od 2km","manje od 2km"]
        [poll_id] => 5
        [answer] => Array
            (
                [0] => stdClass Object
                    (
                        [answer_id] => 2
                        [poll_id] => 5
                        [question_id] => 65
                        [answer] => Answer2-1
                        [created_at] => 2018-07-08 17:36:47
                    )

                [1] => stdClass Object
                    (
                        [answer_id] => 6
                        [poll_id] => 5
                        [question_id] => 65
                        [answer] => Answer2-2
                        [created_at] => 2018-07-09 23:31:31
                    )

            )

    )

我需要一个浏览器中的表格才能看起来像在此处输入图片说明

Question1   Question2   Question3
Answer1-1   Answer2-1   Answer3-1
Answer1-2   Answer2-2   Answer3-2

这是我的代码：

<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>

我的问题是我不能在表的下一行中放置Answer1-2。任何想法？非常感谢

Answer 1

有几种方法可以做到这一点。

将每个预期的列生成为单个元素，并将其放在单元格中。
以您希望显示的方式填充数组
创建一个for(i=0;i<maxAmountOfAnswers;i++)，其中包含另一个foreach（问题）并逐行填充表格。
使用DataTables或其他可以读取json的库。

考虑一下为什么要这么做；语义上的表旨在显示一种数据。有一个很好的理由为什么您不只显示每个问题1个表或根本不显示表？

Answer 2

非常感谢您的回答！这是我的解决办法。

<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>

那是什么样子。
