Research on technology of real-time online customer service system using PHP and Websocket

With the rapid development of the Internet, more and more companies are beginning to realize the importance of online customer service. Implementing online customer service can provide users with faster services and can also bring more business opportunities to enterprises. Traditional online customer service systems are usually implemented based on Ajax or polling, which has obvious real-time deficiencies and increases the burden on the server. This article will introduce a technical method to implement a real-time online customer service system using PHP and Websocket.

1. Introduction to Websocket

Websocket is part of the HTML5 protocol specification and provides a two-way communication mechanism based on the TCP protocol, allowing the server and client to send and receive data in real time. Compared with the HTTP protocol, the Websocket protocol has less overhead in establishing a connection, can respond to client requests faster, and saves bandwidth.

2. Advantages of Websocket

1. Good real-time performance: The communication mechanism based on the Websocket protocol can push data to the client in real time without the client's active query. This improves user experience and satisfaction.
2. Save bandwidth: Since the Websocket protocol implements two-way communication, invalid requests and responses are avoided, effectively reducing the amount of data transmission and reducing the pressure on network bandwidth.
3. More flexible: The Websocket protocol provides a way to customize the protocol to achieve more complex business logic and functional requirements.

3. Technical method of using PHP and Websocket to implement a real-time online customer service system

Using PHP and Websocket to implement a real-time online customer service system, you first need to use the swoole extension of PHP. Swoole is a PHP language extension that enables high-performance asynchronous network communication. The following are the specific steps to use PHP and Websocket to implement a real-time online customer service system:

1. Install the swoole extension

Under the Ubuntu system, use the command line to execute the following commands:

sudo pecl install swoole

2. Write the server program

Write the server program index.php, create a Websocket server, listen to port 8000 and provide support to the client Connect, send and receive functions.

3. Write client program

Write client program client.php to provide online customer service function on the browser side, which can send information to the server and receive feedback information .

4. Client connects to server

When the client accesses the online customer service page, a Websocket connection is established with the server to achieve two-way communication.

5. Client sends information

When the user enters information, the information is sent to the Websocket server. The server sends the information to the client to receive it and returns the feedback information. passed to the client.

4. Summary

Through the introduction of this article, we can understand the technical method of using PHP and Websocket to implement a real-time online customer service system. By providing a two-way communication mechanism and a more efficient network transmission method, Websocket achieves the advantages of real-time, bandwidth saving and more flexibility, which can effectively improve the experience and business value of the online customer service system.
