Simple Chat System using PHP, jQuery, and Ajax with Source Code


This is a Simple Chat System created using PHP/MySQLi and AJAX/jQuery. It features a chat room that is locked by a password depending on the creator of the room. The chats in the room are shown using AJAX/jQuery. This chat system also has an admin panel. The admin user can manage all data of the system except for the chats but he/she can manage/join the room even the user created the room with a password. The admin user can also manage the list and details of users. Talking about the chat room conversation box, the messages are automatically updating with help of the setInterval function.

This Simple Chat System was developed using HTML, PHP, MySQL Database, CSS, Javascript (Ajax and jQuery), and Bootstrap for the design. The bootstrap sources are not yet included along with the source code, I have used only the bootstrap's CDN's.

How to Run


  • Download and Install any local web server such as XAMPP/WAMP.
  • Download the provided source code zip file. (download button is located below)


  1. Open your XAMPP/WAMP's Control Panel and start the "Apache" and "MySQL".
  2. Extract the downloaded source code file.
  3. If you are using XAMPP, copy the extracted source code folder and paste it into the XAMPP's "htdocs" directory. And If you are using WAMP, paste it into the "www" directory.
  4. Browse the PHPMyAdmin in a browser. i.e. http://localhost/phpmyadmin
  5. Create a new database naming "chat_system".
  6. Import the provided SQL file. The file is known as "chat_system.sql" located inside the "db" folder.
  7. Browse the Simple Chat System in a browser. i.e. http://localhost/chat_system

You can test it with 2 different browsers and users.

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
