php - 格式化输出以列出关联数组

Question

我在列出复杂数组的内容时遇到了一些麻烦。该数组包含网站的部分和子部分。

HTML 代码如下所示：

<table class="listing">
                <thead>
                    <tr>
                        <th class="checkable">#</th>
                        <th>Name</th>
                        <th>Type</th>
                        <th>Date added</th>
                        <th class="actions">Actions</th>
                    </tr>
                </thead>
                <tbody>
                    <?php for ($i = 0; $i < count($sections); $i++): ?>
                    <tr <?php if ($i % 2 == 0): ?>class="alt"<?php endif; ?>>
                        <td class="checkable"><?php echo $i+1; ?></td>
                        <td><?php echo stripslashes($sections[$i]['name']); ?></td>
                        <td><?php echo $sections[$i]['type_name']; ?></td>

                </tbody>
            </table>

输出是这样的：http ://cl.ly/image/240C1S2A3J3J

现在这是我的问题：我怎样才能得到正确的编号，怎样才能得到正确的交替行颜色？

您的嵌套循环引起了问题。. . 需要单独的变量来跟踪行。. .
