Interface design and development practice for PHP development of real-time chat function

Introduction:
With the rapid development of the Internet, the demand for real-time communication is becoming more and more urgent. As an important part of Internet applications, real-time chat function is widely used in social networking, e-commerce, customer service and other scenarios. This article aims to introduce how to use PHP language for interface design and development practice of real-time chat function, and provide relevant code examples.

1. Interface design of real-time chat function
The interface design of real-time chat function needs to consider the following aspects:

1. User authentication
   In real-time chat, users Authentication is essential to protect user privacy and information security. Users need to authenticate through the login interface, and this authentication status needs to remain valid.
2. Create a chat room
   Users need to be able to create a chat room and invite other users to join. Interface design needs to consider the size of the chat room, such as how many people can join at the same time, whether it supports group chat, etc.
3. Send Messages
   Users need to be able to send messages to the chat room, and these messages need to be received by other online users in a timely manner. When designing the interface, you need to consider the message format, supported message types (text, pictures, emoticons, etc.) and the message push method (long polling, WebSocket).
4. Receive messages
   Users need to be able to receive messages sent by other users and display them on the chat interface in real time. When designing the interface, you need to consider the message push method and format.
5. Leave the chat room
   When a user leaves the chat room, other online users need to be notified. Interface design needs to consider the triggering conditions for users to leave the chat room and the handling methods when leaving.

2. Development practice of real-time chat function
After the interface design is determined, we can use PHP language to develop and practice the real-time chat function. The following is a simple code example:

1. User authentication interface (auth.php)

2. Create chat room interface (create_room.php)

3. Send message interface (send_message.php)

4. Receive message interface (receive_message.php)

5. Leave chat room interface (leave_room.php)

3. Summary
The interface design and development of real-time chat function is a complex process and needs to consider the user Authentication, creating a chat room, sending messages, receiving messages, and leaving the chat room. This article introduces the interface design and development practice of using PHP language for real-time chat function, and gives corresponding code examples. We hope that readers can gain some understanding of the interface design and development of the real-time chat function through the introduction of this article, thereby providing some reference and guidance for practical applications.
