多维 PHP 阵列到 HTML 表中

Question

我正在尝试在 HTML 表中显示特定域的所有 DNS 记录。

这是显示记录的当前代码：

<?php
$dns = dns_get_record("stackoverflow.com");
print_r($dns);
?>

I want to display the data in an HTML table, like you can see in the DNS Report section here: https://stackoverflow.com.websiteoutlook.com/

应该有 5 列。 这 4 个变量在每个 DNS 记录中：主机、类型、Class、TTL。 然后每条记录都会有一个或多个我想显示的“额外”变量，就像上面的链接一样。

我已经阅读了一些关于使用foreach语句进行循环的教程。 但是，我可以看到的所有示例要么具有硬编码变量，要么是多级 arrays，要么没有在某些 arrays 中可能存在的“额外”字段，但在其他示例中不存在。

任何有关如何生成此表的帮助将不胜感激。

按要求提供$dns的 Output 示例：

我希望下面的代码可以帮助你

<?php
$dns = dns_get_record("stackoverflow.com");
?>

<table>
    <tr>
        <th>Host</th>
        <th>Type</th>
        <th>Class</th>
        <th>TTL</th>
        <th>Extra</th>
    </tr>
    <?php
        foreach($dns as $dnsset) {
            ?>
            <tr>
                <td><?php echo $dnsset["host"] ?></td>
                <td><?php echo $dnsset["type"] ?></td>
                <td><?php echo $dnsset["class"] ?></td>
                <td><?php echo $dnsset["ttl"] ?></td>
                <td>
                    <?php 
                        foreach($dnsset as $extrasetkey => $extrasetvalue) {
                            if(!in_array($extrasetkey, ['host', 'type', 'class', 'ttl'])) {
                                // If your data has extrasetvalue as array type also add conditions
                                // here and loop through them also
                                echo $extrasetkey . ":" . $extrasetvalue . "<br/>";
                            }
                        }
                    ?>
                </td>
            </tr>
            <?
        }
    ?>
</table>
