如何查询MySQL数据库并将结果转换为表格

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "root", "", "test");
if (!$conn) {
  die("连接失败: " . mysqli_connect_error());
}
 
// 查询数据
$sql = "SELECT id, name, email FROM users";
$result = mysqli_query($conn, $sql);
 
// 输出表格
echo "<table>";
echo "<tr><th>ID</th><th>姓名</th><th>邮箱</th></tr>";
while ($row = mysqli_fetch_assoc($result)) {
  echo "<tr>";
  echo "<td>".$row['id']."</td>";
  echo "<td>".$row['name']."</td>";
  echo "<td>".$row['email']."</td>";
  echo "</tr>";
}
echo "</table>";
 
// 关闭连接
mysqli_close($conn);
?>
