如何将从Botman收集的数据持久化到MySQL

<?php
// 连接到MySQL数据库
$mysqli = new mysqli("localhost", "username", "password", "database");

// 检查连接是否成功
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: " . $mysqli->connect_error;
    exit();
}

// 准备插入数据的SQL语句
$sql = "INSERT INTO botman_data (user_id, message, timestamp) VALUES (?, ?, ?)";

// 创建预处理语句
$stmt = $mysqli->prepare($sql);

// 绑定参数
$stmt->bind_param("iss", $user_id, $message, $timestamp);

// 设置参数的值
$user_id = 1;
$message = "Hello, Botman!";
$timestamp = time();

// 执行插入操作
$stmt->execute();

// 关闭预处理语句和数据库连接
$stmt->close();
$mysqli->close();
?>

<?php
// 连接到MySQL数据库（同上）

// 准备查询数据的SQL语句
$sql = "SELECT * FROM botman_data";

// 执行查询操作
$result = $mysqli->query($sql);

// 处理查询结果
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"] . "<br>";
        echo "User ID: " . $row["user_id"] . "<br>";
        echo "Message: " . $row["message"] . "<br>";
        echo "Timestamp: " . $row["timestamp"] . "<br>";
        echo "<br>";
    }
} else {
    echo "No data found.";
}

// 关闭数据库连接
$mysqli->close();
?>
