この sql ステートメントから取得したデータを含む html テーブルがあります。

$sql = "SELECT log_date, log_id, log_time, network_protocal, client_name, client_ip FROM log_table";

HTML は次のとおりです。

<div class="container">

<table class="table table-striped">
    <tr>
        <td>Date</td>
        <td>Time</a></td>
        <td>Network Protocol</td>
        <td>Client Name</td>
        <td>Client IP</td>
    </tr>
    <?php foreach ($logs as $log) { ?>
        <tr>
            <td><?php if (isset($log->log_date)) echo (string)$log->log_date; ?></td>
            <td><?php if (isset($log->log_time)) echo (string)$log->log_time; ?></td>
            <td><?php if (isset($log->network_protocal)) echo (string)$log->network_protocal; ?></td>
            <td><?php if (isset($log->client_name)) echo (string)$log->client_name; ?></td>
            <td><?php if (isset($log->client_ip)) echo (string)$log->client_ip; ?></td>
        </tr>
    <?php } ?>
</table>

テーブル ヘッダーをクリックして昇順および降順の並べ替え機能を設定したいのですが、これに対する簡単な解決策が見つからないようです。誰かが私を正しい方向に向けることができますか?

here the solution hope this will help you

<?php


$sql = "SELECT log_date, log_id, log_time, network_protocal, client_name, client_ip
 FROM log_table $sort";




$sort = "";
    if(isset($_GET['sort'])) {
        switch ($_GET['sort'] ) {
        case 0: 
                    $sort = " ORDER BY log_date ASC"; 
                    break;
                     case 1: 
                    $sort = " ORDER BY log_date DESC"; 
                    break;
