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

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:

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

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

1. Front-end code:

      
  
  发送   

2. styles.css code:

#chatbox { height: 300px; overflow-y: scroll; border: 1px solid #ccc; padding: 10px; } #message { width: 300px; } button { margin-top: 10px; }

3. 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); } }); }

4. send_message.php code:

        

         Copy after login
        
       

5. get_messages. PHP code:

        

         Copy after login
        
       

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:

1. 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); } }); }

2. send_red_packet.php code:

        

         Copy after login
        
       

3. receive_red_packet.php code:

        

         Copy after login
        
       

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:

1. 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; }

2. send_group_message.php code:

        

         Copy after login
        
       

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

Summary
This article introduces how to use PHP to implement the message red envelope and group sending functions of the real-time chat function, and provides corresponding code examples. Through the above code, you can modify and expand it according to actual needs to achieve more functions. I hope this article is helpful to you and I wish you happy development!
