如何用PHP在我的数据库中保存数据

<?php
// 连接数据库
$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);
}

// 准备SQL语句
$sql = "INSERT INTO your_table (column1, column2, column3) VALUES (?, ?, ?)";

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

// 绑定参数
$stmt->bind_param("sss", $value1, $value2, $value3);

// 设置参数值
$value1 = "Value 1";
$value2 = "Value 2";
$value3 = "Value 3";

// 执行预处理语句
$stmt->execute();

// 获取插入的记录ID
$insertedId = $stmt->insert_id;

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