php - 重复从数据库中选择下拉列表值

Question

我正在使用 PHP 更改数据库中下拉列表菜单的值。 我使用的状态是:新建-进度-等待-完成-关闭 假设所有新条目的状态都是“NEW”

当我更改值时，我仍然可以看到双重选项。

这是我的代码:

<td>
    <select class='form-control col-sm-10' id='status' name='status'>
        <option value=" . $row['status'] . " >" . $row['status'] . "</option>
        <option value='new'>New</option>
        <option value='progress'>Progress</option>
        <option  value='wait'>Wait</option>
        <option value='done'>Done</option>
        <option value='close'>Close</option>
    </select>
</td>
