Многомерный PHP-массив в HTML-таблицу

Question

Я пытаюсь отобразить все записи DNS для определенных доменов в таблице HTML.

Вот текущий код, который показывает мне записи:

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

Я хочуотобразить данные в таблице HTML, как вы можете видеть в разделе «Отчет DNS» здесь: https://stackoverflow.com.websiteoutlook.com/

Должно быть 5 столбцов. Эти 4 переменные находятся в каждой записи DNS: Host, Type, Class, TTL. Тогда у каждой записи будет одна или несколько «дополнительных» переменных, которые я хочу отобразить, как показано в приведенной выше ссылке.

Я прочитал несколько уроков о циклическом выполнении операторов foreach. Однако все примеры, которые я вижу, имеют либо жестко закодированные переменные, либо многоуровневые массивы, либо не имеют «лишних» полей, которые могут существовать в некоторых массивах, но не в других.

Любая помощь в том, какдля создания этой таблицы будет принята с благодарностью.

Пример вывода $dns по запросу:

Надеюсь, приведенный ниже код может вам помочь

<?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>
            <?
