Research on real-time massive data transmission technology using PHP and WebSocket

With the continuous improvement of informatization in modern society, the amount of data on the Internet has shown an explosive growth trend. How to efficiently transmit and process these massive data has become an important research direction in the Internet field. To this end, this article discusses the relevant research content of using PHP and WebSocket to realize real-time massive data transmission technology.

1. Introduction to WebSocket

WebSocket is a full-duplex communication protocol based on the TCP protocol, which can establish real-time, two-way, and An efficient data transmission channel effectively solves the problem of the server being unable to actively push data to the client in the traditional HTTP request-response mode.

2. Implementation of PHP and WebSocket

As one of the most popular web application development languages, PHP has a large user group and strong community support. To implement data transmission between PHP and WebSocket, you can use the Swoole extension to achieve efficient data transmission through the cooperation of Swoole's WebSocket server and WebSocket client.

The following describes the implementation of the WebSocket server and WebSocket client in Swoole.

1. WebSocket Server

In Swoole, the WebSocket server can be easily established by the following code:

$server = new swoole_websocket_server("0.0.0.0", 9501);

$server->on('open', function (swoole_websocket_server $server, $request) {

echo "client {$request->fd} connected
";
});

$server->on('message', function (swoole_websocket_server $server, $frame) {

echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}
";
foreach ($server->connections as $fd) {

$server->push($fd, $frame->data);
}
});

$server->on('close', function ($ser, $fd) {

echo "client {$fd} closed
";
});

$server->start();

The server code transfers from the client to the server When a request is made, the response content is sent and the received request is sent to all client connections.

2. WebSocket Client

Different from the WebSocket server, the WebSocket client needs to actively send requests to the server. Through the following code, the establishment of the WebSocket client can be achieved:

$client = new swoole_websocket_client('127.0.0.1', 9501);
$client->on("open", function($client){
echo "connect success
";
});

$client->on("message", function($client, $frame){
echo "receive: {$frame->data}
";
});

$client->on("close", function($client){
echo "close
";
});

$client->connect();

By establishing the WebSocket client, you can send data to the WebSocket server and receive data returned by the server, thereby achieving efficient data transmission.

3. Real-time massive data transmission technology

Based on the implementation of PHP and WebSocket, an efficient real-time massive data transmission technology can be realized, thereby realizing the need for real-time processing and transmission of large amounts of data. .

For example, in the financial field, real-time monitoring and analysis of stocks and other securities are required, and the transaction data of these securities exhibits massive characteristics. By utilizing PHP and WebSocket technologies, real-time transmission and processing of these data can be achieved, so that market anomalies can be discovered in a timely manner and corresponding strategy adjustments can be made in a timely manner.

IV. Conclusion

This article introduces the relevant research content of using PHP and WebSocket to realize real-time massive data transmission technology. Through the WebSocket server and WebSocket client provided by the Swoole extension, real-time and efficient data transmission can be achieved, providing new ideas and methods for data processing and analysis in the field of big data.
