如何将模态表单连接到mysql数据库？

<?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, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 处理表单提交
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST["name"];
    $email = $_POST["email"];
    // 其他表单字段...

    // 将数据插入到数据库表中
    $sql = "INSERT INTO your_table (name, email) VALUES ('$name', '$email')";
    if ($conn->query($sql) === TRUE) {
        echo "数据插入成功";
    } else {
        echo "数据插入失败: " . $conn->error;
    }
}

// 关闭数据库连接
$conn->close();
?>
