我正在关注基本php表的教程以向用户显示 http://www.killersites.com/community/index.php?/topic/1969-basic-php-system-vieweditdeleteadd-records/
我遇到的问题是我的平台不支持MySQL所以我将其更改为MySQL
第二个问题是我在桌面上方显示的用户
这是一张更好描述的图片： http://store2.up-00.com/2014-02/1391915459381.jpg
这是我正在使用的代码：

如果您想稍后添加额外的单元格，请遵循相同的约定。
// echo out the contents of each row into a table
echo "<tr>";
while($row = mysqli_fetch_assoc($result)) {
$id = $row['id'];
$fname = $row['first_name'];
$lname = $row['last_name'];
echo "<tr><td>"; // do not modify
echo $id;
echo "</td>"; // do not modify
echo "<td>";
echo $fname;
echo "<td>";
echo $lname;
// there should not be anything below this
// besides the echo "</td></tr>";
echo "</td></tr>"; // do not modify
}
我为$lname = $row['lname'];列和Last Name以及其他一些内容添加了echo $lname;。因此，您可能需要修改$lname = $row['lname'];以适合您的用途。

请尝试以下完整代码。
我在<td>和echo "<tr>";中添加</td> echo "</tr>";
