如何将这个PHP表单与Google Recaptcha POST一起发送到不同的URL？

<?php
// 获取用户提交的表单数据
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$recaptchaResponse = $_POST['g-recaptcha-response'];

// 验证Recaptcha响应
$secretKey = 'YOUR_SECRET_KEY';
$verifyUrl = 'https://www.google.com/recaptcha/api/siteverify';
$data = array(
    'secret' => $secretKey,
    'response' => $recaptchaResponse
);

$options = array(
    'http' => array(
        'header' => "Content-type: application/x-www-form-urlencoded\r\n",
        'method' => 'POST',
        'content' => http_build_query($data)
    )
);

$context = stream_context_create($options);
$response = file_get_contents($verifyUrl, false, $context);
$recaptchaResult = json_decode($response);

// 检查Recaptcha验证结果
if ($recaptchaResult->success) {
    // 验证成功，将表单数据POST到不同的URL
    $postUrl = 'https://example.com/submit-form.php';
    $postData = array(
        'name' => $name,
        'email' => $email,
        'message' => $message
    );

    $postOptions = array(
        'http' => array(
            'header' => "Content-type: application/x-www-form-urlencoded\r\n",
            'method' => 'POST',
            'content' => http_build_query($postData)
        )
    );

    $postContext = stream_context_create($postOptions);
    $postResponse = file_get_contents($postUrl, false, $postContext);

    // 处理POST响应
    // ...
} else {
    // 验证失败，给用户一个错误提示
    echo 'Recaptcha verification failed.';
}
?>
