But not only for posting, in this tutorial will you also learn on how to create a comment on the post being posted.

Let’s start our tutorial.
Posting Status Updates with Comment Like Facebook Using PHP/MySQL Steps:
First, create a database then name it as any name you desire. In my case I use “itsourcecode” as my database name.
Then create table then name it as “posts” then put the following attributes.
[sql]
CREATE TABLE `posts` (
`post_id` int(11) NOT NULL,
`post_name` text NOT NULL,
`post_msg` text NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
[/sql]Create another table then name it as “comments” then put the following attributes.
[sql]
CREATE TABLE `comments` ( `comment_id` int(11) NOT NULL, `post_id` int(11) NOT NULL, `user_name` text NOT NULL, `user_comment` text NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1;
[/sql]For the CSS, create a “styles.css” file then put the following CSS codes.
[css]
body {
background-color: #5E5E5E;
color: #000000;
width: 70%;
margin: auto;
font: 15px Calibri;
padding-top: 20px;
}
.body {
background-color: #E5E5E5;
padding: 10px;
margin-top: 5px;
}
textarea {
background-color: #ffffff;
padding: 10px;
border-radius: 3px;
border: 1px solid #c0c0c0;
margin: 3px;
margin-bottom: 0px;
}
input[name='uname'] {
background-color: #ffffff;
padding: 10px;
border-radius: 3px;
margin: 3px;
margin-bottom: 4px;
margin-top: 0px;
border: 1px solid #c0c0c0;
width: 154px;
}
.post-panel {
background-color: #FFFFFF;
border: 1px solid #c0c0c0;
margin-bottom: 10px;
border-radius: 5px;
}
.post-header {
padding: 10px;
}

padding: 10px;
border-top: 1px solid #c0c0c0;
}
.post-footer {
padding: 10px;
border-top: 1px solid #c0c0c0;
}
input[type='submit'] {
background-color: #FFFFFF;
border: 1px solid #c0c0c0;
padding: 10px;
border-radius: 3px;
margin: 3px;
margin-top: 0px;
}
a {
color: #0005FF;
text-decoration: none;
}
[/css]For the connection to the database. Create a “connection.php” file then put the following codes.
[php]
<?php
$mysqli = new MySQLi('localhost', 'root', '', 'itsourcecode');
?>
[/php]Create an “index.php” file then put the following codes.
[php]
<?php include ("connection.php");?>

Frequently Asked Questions
How does this PHP Point of Sale system work?
Cashier UI for adding items to cart, scanning barcodes, applying discounts, accepting cash/card, printing receipts (window.print or TCPDF). Real-time inventory deduction. Daily Z-report.
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.
where are the sql tables??
