Comments are usually seen on a website that provide articles and tutorials. This is how web users exchange ideas to make better website and more reliable articles.
In this comment system, you can write a comment and post it without refreshing the page.
Below are the step by step process to follow:
- Create a MySQL database ang name it “dbcomment“.
- Do this following code for creating table in the database that you have created.
CREATE TABLE IF NOT EXISTS `tblcomment` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `PERSON` varchar(50) NOT NULL, `COMMENT` text NOT NULL, `DATEPOSTED` datetime NOT NULL, PRIMARY KEY (`ID`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
- Create a page for the configuration between MySQL database and PHP script.
<?php
$server = 'localhost';
$dbuser = 'root';
$dbpass = '';
$dbname = 'commentdb';
$con = mysql_connect($server, $dbuser, $dbpass);
if (isset($con)) {
# code...
$dbSelect = mysql_select_db($dbname);
if (!$dbSelect) {
echo "Problem in selecting database! Please contact administraator";
die(mysql_error());
}
} else {
echo "Problem in database connection! Please contact administraator";
die(mysql_error());
}
?>- Create a landing page and name it “index.php“.
<?php include 'config.php'; ?>

Frequently Asked Questions
How does this PHP project work?
Built with vanilla PHP (no framework) and MySQL backend. Standard structure: form HTML, PHP script handlers, MySQL via PDO or mysqli, sessions for auth, Bootstrap for responsive layout. Ready to extend for BSIT capstone scope.
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.
