Using PHP to implement real-time chat function, message red envelope and group sending function

With the development of social media, chat function has become one of the essential functions of various applications. one. When developing chat functions, it is often necessary to implement message red envelope and group sending functions to increase the user's interactive experience. This article will introduce how to use PHP to implement these two functions and provide code examples for reference.

Implementation of real-time chat function
The implementation of real-time chat function usually involves multiple technologies, including front-end real-time communication framework, back-end server and database, etc. In this article, we will use the following technologies to implement live chat functionality:

Front-end technologies: HTML, CSS, and JavaScript/jQuery.
Backend technology: PHP and MySQL.

The following is a code example for PHP to implement real-time chat:

Front-end code:

<!DOCTYPE html>
<html>
<head>
    <title>实时聊天</title>
    <link rel="stylesheet" type="text/css" href="styles.css">
    <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
</head>
<body>
    <div id="chatbox"></div>
    <input type="text" id="message" placeholder="输入消息">
    <button onclick="sendMessage()">发送</button>
    <script src="script.js"></script>
</body>
</html>

styles.css code:

#chatbox {
    height: 300px;
    overflow-y: scroll;
    border: 1px solid #ccc;
    padding: 10px;
}

#message {
    width: 300px;
}

button {
    margin-top: 10px;
}

script.js code:

function sendMessage() {
    var message = $('#message').val();
    $.ajax({
        url: 'send_message.php',
        method: 'POST',
        data: {message: message},
        success: function(response) {
            $('#message').val('');
        }
    });
    return false;
}

setInterval(getMessages, 1000);

function getMessages() {
    $.ajax({
        url: 'get_messages.php',
        method: 'GET',
        success: function(response) {
            $('#chatbox').html(response);
            $('#chatbox').scrollTop($('#chatbox')[0].scrollHeight);
        }
    });
}

send_message.php code:

<?php
$message = $_POST['message'];

// 将消息保存到数据库中
// 代码略...

// 返回成功响应
echo 'success';

get_messages. PHP code:

<?php
// 从数据库中获取聊天记录
// 代码略...

// 将聊天记录返回给前端
// 代码略...

The above is the basic implementation of the real-time chat function. Messages can be sent and received through the front-end page.

Implementation of the message red envelope function
The message red envelope function allows users to send red envelopes in chat, and other users can receive the red envelopes. The following is a code example to implement the message red envelope function:

Front-end code:

function sendRedPacket() {
    var amount = $('#amount').val();
    $.ajax({
        url: 'send_red_packet.php',
        method: 'POST',
        data: {amount: amount},
        success: function(response) {
            $('#amount').val('');
        }
    });
    return false;
}

function receiveRedPacket(redPacketId) {
    $.ajax({
        url: 'receive_red_packet.php',
        method: 'POST',
        data: {redPacketId: redPacketId},
        success: function(response) {
            alert(response);
        }
    });
}

send_red_packet.php code:

<?php
$amount = $_POST['amount'];

// 发送红包到数据库中
// 代码略...

// 返回成功响应
echo '红包发送成功';

receive_red_packet.php code:

<?php
$redPacketId = $_POST['redPacketId'];

// 领取红包的逻辑处理
// 代码略...

// 返回成功响应
echo '红包领取成功';

Through the above code, users can send red envelopes, and other users can receive red envelopes.

Implementation of group sending function
The group sending function allows users to send messages to multiple people. The following is a code example to implement the group sending function:

Front-end code:

function sendGroupMessage() {
    var message = $('#message').val();
    $.ajax({
        url: 'send_group_message.php',
        method: 'POST',
        data: {message: message},
        success: function(response) {
            $('#message').val('');
        }
    });
    return false;
}

send_group_message.php code:

<?php
$message = $_POST['message'];

// 群发消息的逻辑处理
// 代码略...

// 返回成功响应
echo '消息发送成功';

Through the above code, users can send messages to multiple people.

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
