Question

所以我目前正在为我的社区构建一个新的CMS，并遇到了一个小问题。我希望能够将命令链中最高级别的排名列为最低，但我无法使用基于字符串的排名来解决这个问题。

    <?php
    include "dbh.php";
    include "header.php";
    $sql = "SELECT * FROM users_leo";
    $result = $conn->query($sql);
    $row = $result->fetch_assoc();
    $rank = $row["rank"];
    $department = $row["department"];



    ?>
    <div class="login-page">
    </div>
    <div class='form'>
    <?php
    $sql = "SELECT * FROM users_leo";
    $result = $conn->query($sql);

    if ($result->num_rows > 0) {
    echo "<table>
     <tr>
        <th>In-Game Name</th>
        <th>Rank</th>
        <th>Department</th>
        <th>Profile</th>
     </tr>";
      while($row = $result->fetch_assoc()) {
        echo "<tr>";
        echo "<td>"; echo $row['username']; echo"</td>";
        echo "<td>"; echo $row['username']; echo"</td>";
        echo "<td>"; echo $row['department'];  echo"</td>";
        echo '<td><a class="viewProfile" href="profile.php?id=' . $row['id']. '"><button>View Profile</button></a></td>';
        echo "</tr>";

    }
}
    ?>

  </div>
</div>
  </body>

正如您可以在下面的代码中看到的那样，等级存储为字符串

 echo "<select name='rank'>
<option value='Corrections Officer'>Corrections Officer</option>
<option value='Senior Corrections Officer'>Senior Corrections Officer</option>
<option value='DOC Corporal'>DOC Corporal</option>
<option value='DOC Sergeant'>DOC Sergeant</option>
<option value='DOC Lieutenant'>DOC Lieutenant</option>
<option value='DOC Head Lieutenant'>DOC Head Lieutenant</option>
<option value='DOC Command'>DOC Command</option>
<option value='Trooper 3rd class'>Trooper 3rd Class</option>
<option value='Trooper 2nd class'>Trooper 2nd Class</option>
<option value='Trooper 1st class'>Trooper 1st Class</option>
<option value='Lance Corporal'>Lance Corporal</option>
<option value='State Corporal'>State Corporal</option>
<option value='State Sergeant'>State Sergeant</option>
<option value='First Sergeant'>First Sergeant</option>
<option value='2nd Lieutenant'>2nd Lieutenant</option>
<option value='1st Lieutenant'>1st Lieutenant</option>
<option value='State Command'>State Command</option>
<option value='Officer'>Officer</option>
<option value='Senior Officer'>Senior Officer</option>
<option value='Police corporal'>Police Corporal</option>
<option value='Police Sergeant'>Police Sergeant</option>
<option value='Staff Sergeant'>Staff Sergeant</option>
<option value='Police Lieutenant'>Police Lieutenant</option>
<option value='Police Head Lieutenant'>Police Head Lieutenant</option>
<option value='PD Command'>PD Command</option>
<option value='Overseer'>Overseer</option>
    </select>

我已经尝试过但无法找到解决方案P.S.如果有人可以解释如何设置它以便将它们显示为字符串，我愿意将所有等级更改为数字。

如果你想从最高到最低的顺序选择字符串，那么代码ASC [升序降级]和DESC [降序升序]

SELECT * FROM users_leo ORDER BY column_name ASC [or] DESC;

如何为我的用户设置自定义加载顺序显示基于排名的表
