Php 如何显示来自数据库的时间提醒

我有一个显示数据库数据的表。例如，类似这样的内容：

<table>                       
  <tr>
    <th>Title</th>
    <th>Date</th>
    <th>Start Time</th>
    <th>End Time</th>
  </tr>
  <tr>
    <td>French</td>
    <td>21 December 1992</td>
    <td>23:00</td>
    <td>05:00</td> 
  </tr>

------

开始时间：
结束时间：

尝试下面的代码。您可以使用“$sql->start\u time”代替“$start\u time”，使用“$sql->date”代替“$start\u date”。检查一下你的行李

上述代码给出的输出为：

剩余2小时/22分钟/30秒

您可以根据需要进行编辑。

谢谢，这很有帮助。虽然，我真的不知道为什么我得到这么多的反对票。我不明白。谢谢你的帮助。
