php导出mysql数据库表结构

<?php
// 连接到MySQL数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 查询表结构
$sql = "SHOW TABLES";
$result = $conn->query($sql);

// 解析和输出表结构
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $tableName = $row['Tables_in_' . $dbname];
