Good day everyone! Today, I will teach you how to create a SIMPLE FORUM Using PHP/MYSQL. This tutorial gives a big help for all web developers who wants to develop their own forum site.
Like the real forum, in this tutorial you can create your forum with add topic board function, post threads, comment to threads, and count all the topics posted in each topic board.
So first, create a database, name it as any name you desire. In my case, I use “itsourcecode” as the name of the database.
Then create a table name, it as “boards” then put the following attributes.
[sql]CREATE TABLE `boards` ( `board_id` int(11) NOT NULL, `board_name` text NOT NULL ) ENGINE=MyISAM DEFAULT CHARSET=latin1;[/sql]Then create again another table, name it as “threads” then put the following attributes.
[sql]CREATE TABLE `threads` ( `thread_id` int(11) NOT NULL, `board_id` int(11) NOT NULL, `thread_title` text NOT NULL, `thread_content` text NOT NULL ) ENGINE=MyISAM DEFAULT CHARSET=latin1;[/sql]For the connection to the database, create “connection.php” file then put the following codes.
[php]<?php
$mysqli = new mysqli('localhost', 'root', '', 'itsourcecode');
?>[/php]In the ‘’index.php” file, put the following codes.
[php]<?php include 'connection.php' ?>
<!DOCTYPE html>

<h3>ITSOURCECODE Simple Forum in PHP/MYSQL</h3>
<a href="add-board.php">Add New Topic Board</a><br>
<?php
$boards = $mysqli->query("SELECT * FROM boards");
while ($board_data = $boards->fetch_assoc()) {
$threads = $mysqli->query("SELECT * FROM threads WHERE board_id = ".$board_data['board_id']."");
?>
<br>
<b>#<?php echo $board_data['board_id'] ?></b> <a href="view-board.php?board_id=<?php echo $board_data['board_id'] ?>"><?php echo $board_data['board_name'] ?></a> [<b><?php echo $threads->num_rows ?></b> Topics]
<?php }
if ($boards->num_rows == null) {
echo '<br>no topic board created yet';
}
?>
</body>
</html>
[/php]For adding new topic board, create “add-board.php” file then put the following codes.
[php]<?php include 'connection.php'; ?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Add New Topic Board</title>
</head>
<body>
<a href="index.php">Home</a> | Add New Topic Board<br><br>
<form method="post" action="add-board-action.php">
<label>Board title:</label><br>
<input type="text" name="title" /><br><br>
<input type="submit" name="add_title" value="Add" />
</form>
</body>
</html>
[/php]For the add board action, create “add-board-action.php” file then put the following codes.
[php]<?php
include 'connection.php';
if (isset($_POST['add_title'])) {
$title = $_POST['title'];
$add_title = $mysqli->query("INSERT INTO boards (board_name) VALUES ('$title')");
if ($add_title) {
header("Location: index.php");
} else {
echo $mysqli->error;
}
}
?>[/php]And now, for viewing the created topic board, create a “view-board.php” file then put the following codes.
[php]<?php
include 'connection.php';
$board_id = $_GET['board_id'];
$get_board = $mysqli->query("SELECT * FROM boards WHERE board_id = $board_id");
$board_data = $get_board->fetch_assoc();
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

<body>
<a href="index.php">Home</a> | <b><?php echo $board_data['board_name']; ?></b><br><br>
<a href="add-thread.php?board_id=<?php echo $board_id ?>">Post New Thread</a><br><br>
<?php
$threads = $mysqli->query("SELECT * FROM threads WHERE board_id = $board_id");
while ($thread_data = $threads->fetch_assoc()) { ?>
<b>#<?php echo $thread_data['thread_id'] ?></b> <a href="view-thread.php?thread_id=<?php echo $thread_data['thread_id'] ?>&board_id=<?php echo $board_id ?>"><?php echo $thread_data['thread_title'] ?></a>
<?php }
if ($threads->num_rows == null) {
echo '<br><br>no threads posted yet';
}
?>
</body>
</html>
[/php]For posting threads to every board. Create a “add-thread.php” file then put the following codes.
[php]<?php
include 'connection.php';
$board_id = $_GET['board_id'];
$get_board = $mysqli->query("SELECT * FROM boards WHERE board_id = $board_id");
$board_data = $get_board->fetch_assoc();
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Add New Thread</title>
</head>
<body>
<a href="index.php">Home</a> | <?php echo $board_data['board_name'] ?> | <b>Add Thread</b><br><br>
<form method="post" action="add-thread-action.php?board_id=<?php echo $board_id ?>">
<label>Title:</label><br>
<input type="text" name="title" /><br>
<label>Content:</label><br>
< t e x t a r e a name="content" >< / t e x t a r e a ><br><br>
<input type="submit" name="post_thread" value="Post" />
</form>
</body>
</html>
[/php]Then for the action in adding thread. Create a “add-thread-action.php” file then put the following codes.
[php]<?php
include 'connection.php';
if (isset($_POST['post_thread'])) {
$board_id = $_GET['board_id'];
$title = $_POST['title'];
$content = $_POST['content'];
$post_thread = $mysqli->query("INSERT INTO threads (board_id, thread_title, thread_content) VALUES ($board_id, '$title', '$content')");
if ($post_thread) {
header("Location: view-board.php?board_id=$board_id");
} else {
echo $mysqli->error;
}
}
?>[/php]For viewing the posted topic. Create a “view-thread.php” file then put the following codes.
[php]<?php
include 'connection.php';
$board_id = $_GET['board_id'];
$thread_id = $_GET['thread_id'];
$get_board = $mysqli->query("SELECT * FROM boards WHERE board_id = $board_id");
$board_data = $get_board->fetch_assoc();
$get_thread = $mysqli->query("SELECT * FROM threads WHERE thread_id = $thread_id");
$thread_data = $get_thread->fetch_assoc();
?>

Technology stack and requirements
To run this PHP project, you need these tools on your development machine:
- XAMPP or WAMP server. Bundles Apache, MySQL, and PHP so you can run PHP on Windows without individual installs. Free from apachefriends.org.
- PHP 8.0 or higher. Included with XAMPP. Older versions (5.x, 7.x) may work but modern PHP features improve security and performance.
- MySQL or MariaDB. Comes with XAMPP. phpMyAdmin manages the database through a browser UI.
- VS Code or PhpStorm. Free code editor with PHP syntax highlighting, IntelliSense, and debugging support.
- Web browser. Chrome, Firefox, or Edge for testing the running app.
Installing the source code
- Download the archive. Get the ZIP file from the download link on this page and extract it.
- Move to htdocs. Place the extracted folder inside C:\xampp\htdocs\ so Apache can serve it.
- Import the database. Open http://localhost/phpmyadmin, click Import, and select the .sql file included in the archive.
- Update database credentials. Open the config.php or connection.php file and set the correct database name, username, and password (default XAMPP: root / empty password).
- Run the project. Start Apache + MySQL in XAMPP, then visit http://localhost/your-project-folder/ in a browser.
Using this project for your BSIT capstone
This PHP project maps cleanly to standard BSIT capstone documentation. Suggested chapter alignment:
- Chapter 1 (Introduction). Discuss the problem the system solves in real-world context. Cite Philippine business or academic use cases where a manual process could be replaced.
- Chapter 2 (Review of Related Literature). Compare this system’s features against 5-10 similar published projects. Cite journals like IJERT or IEEE Access for academic-standard sources.
- Chapter 3 (Methodology). Include Use Case Diagram, Data Flow Diagram, Entity Relationship Diagram, and Activity Diagram covering all major workflows.
- Chapter 4 (Results and Discussion). Screenshot each module of the running system with a caption explaining what data it processes and which user role interacts with it.
- Chapter 5 (Conclusion and Recommendations). Identify features that could be added in a Version 2, such as mobile app, REST API export, or AI-powered analytics.
Modules typical of Create a Simple Forum Using PHP/MYSQL
- Master data. CRUD forms for the primary entities with search and filter.
- Transaction processing. Data entry forms for day-to-day operations the system automates.
- Reports. Formatted printable output summarizing activity per day, user, or category.
- User management. Login with role-based permissions (Admin, Encoder, Viewer).
- Backup and restore. Export database to a .sql file and restore when needed.
Common enhancements for capstone review
- Modernize the UI. Add Bootstrap 5 or Tailwind CSS for a polished appearance.
- Add printable receipts. Use TCPDF or FPDF to generate PDF reports.
- Multi-user concurrency. Ensure database handles simultaneous writes without lost-update errors.
- Rewrite in Laravel. Migrate to Laravel for maintainability and modern development patterns.

Frequently Asked Questions
How does this PHP discussion forum work?
Categories, Topics, Posts hierarchy. User auth via PHP sessions, role-based moderator/admin permissions. Posts support BBCode or limited HTML. Reply notifications via PHP mail().
What PHP and MySQL versions does this project require?
Most projects in this batch run on PHP 7.4 to PHP 8.2 with MySQL 5.7+ or MariaDB 10+. A few older projects need PHP 5.6 (deprecated, use XAMPP 7.x). To run: install XAMPP / WAMP / Laragon, extract project to htdocs, import the included .sql file via phpMyAdmin, edit the connection file (usually config.php or db_connect.php) with your DB credentials, browse to the project URL in your browser.
How do I set up the database for this PHP project?
Open phpMyAdmin (http://localhost/phpmyadmin/ on XAMPP), create a new empty database with the name specified in the project’s config.php. Click the Import tab, choose the included .sql file, click Go. Then edit config.php (or includes/connection.php) with: ‘localhost’, your MySQL username (usually ‘root’), your MySQL password (usually blank for XAMPP), and the database name.
Can I use this PHP project for a BSIT capstone or thesis?
Yes, but extend it. A bare CRUD app is too narrow for full capstone scope. Add: user roles via session checks, reports/dashboards (Chart.js + AJAX), PDF exports (TCPDF library), email notifications (PHPMailer), real domain extension (analytics, audit log, multi-branch support). Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘connection error’ or ‘undefined function mysqli_connect’?
Three common PHP issues: (1) Connection error: Apache + MySQL services not running in XAMPP control panel, OR database name in config.php does not match what you created in phpMyAdmin. (2) ‘undefined function mysqli_connect’: MySQL extension not enabled, in php.ini uncomment extension=mysqli (then restart Apache). (3) ‘No such file or directory’: MySQL socket path wrong, use 127.0.0.1 instead of localhost in the connection string.
Where can I find more PHP projects with source code?
Browse the PHP Projects hub for the full library (300+ vanilla PHP systems). For modern PHP MVC alternatives see Laravel Projects (74 systems) or CodeIgniter Projects (32 systems). For BSIT-focused capstone idea lists see 150 Best Capstone Project Ideas.
What’s up, all is going perfectly here and ofcourse every one is sharing facts, that’s really good, keep up writing.
thanks its is very used full
