如何通过php脚本将多个输入从表单发送到电子邮件

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // 获取表单数据
    $name = $_POST["name"];
    $email = $_POST["email"];
    $message = $_POST["message"];

    // 验证和处理表单数据
    // ...

    // 构建电子邮件内容
    $subject = "新消息来自表单";
    $body = "姓名: " . $name . "\n";
    $body .= "邮箱: " . $email . "\n";
    $body .= "消息: " . $message . "\n";

    // 发送电子邮件
    $to = "recipient@example.com";
    $headers = "From: sender@example.com";

    if (mail($to, $subject, $body, $headers)) {
        echo "邮件发送成功！";
    } else {
        echo "邮件发送失败！";
    }
}
?>
