c# - 异步 HttpWebRequest 上的此 .net/C# 代码的 PHP 等效项、自定义 header 二进制有效负载和分析响应

Question

我正在寻找与以下代码等效的 PHP，即使它不是可编译的代码，只要提供用于执行这些功能的高级函数就很好了。

        string subscriptionUri = "sample.com";
        HttpWebRequest sendNotificationRequest = (HttpWebRequest)WebRequest.Create(subscriptionUri);
        sendNotificationRequest.Method = "POST";

        sendNotificationRequest.Headers.Add("X-MessageID", "<UUID>");
        sendNotificationRequest.ContentType = "text/xml";


        sendNotificationRequest.ContentLength = notificationMessage.Length;
        byte[] notificationMessage = new byte[] {<payload>};

        using (Stream requestStream = sendNotificationRequest.GetRequestStream())
        {
           requestStream.Write(notificationMessage, 0, notificationMessage.Length);
        }

        // Sends the notification and gets the response.
        HttpWebResponse response = (HttpWebResponse)sendNotificationRequest.GetResponse();
        string notificationStatus = response.Headers["X-NotificationStatus"];
        string notificationChannelStatus = response.Headers["X-SubscriptionStatus"];
        string deviceConnectionStatus = response.Headers["X-DeviceConnectionStatus"];

所以基本上我正在寻找 PHP 等同于以下内容

1. 发送带有一些自定义 header 和内容类型的异步请求并将其发送为异步/流
2. 从字符串中创建一个以字节为单位的有效载荷
3. 获取响应并查看 header 。
