如何在php中捕获JSON数据以将其发送到我的电子邮件

<?php
// 接收JSON数据
$jsonData = file_get_contents('php://input');

// 解析JSON数据
$data = json_decode($jsonData);

// 构建电子邮件内容
$emailContent = "Name: " . $data->name . "\n";
$emailContent .= "Email: " . $data->email . "\n";
$emailContent .= "Message: " . $data->message . "\n";

// 设置电子邮件头部信息
$to = "recipient@example.com";
$subject = "New message from website";
$headers = "From: sender@example.com\r\n";
$headers .= "Reply-To: " . $data->email . "\r\n";

// 发送电子邮件
$mailSent = mail($to, $subject, $emailContent, $headers);

// 检查邮件是否成功发送
if ($mailSent) {
    echo "Email sent successfully.";
} else {
    echo "Failed to send email.";
}
?>
