This tutorial is all about Insert and Display Data in PHP & MYSQL Without Refreshening Page. In this tutorial you will learn Insert and Display Data in PHP & MYSQL Without Refreshening Page.
Good Day! Everyone! Today I’m going to teach you my inserting and displaying data in your database.
Unlike with my previous tutorial which is about a very simple way in inserting and showing data in database. Here, you don’t need to refresh your page in order to display the inserted data and we add some styles now.
So before you go with this tutorial, for the beginners, I suggest to start with my previous tutorial regarding simple way of inserting and displaying data in PHP. >> click here << to go my previous article.
So now, we will going to start our tutorial.
Make sure you already have the following. You can download it below:
Now, if you are already done downloading all the files below. Just go now to your browser then go to PHPMYADMIN to create a database.
Create a database then name it as any name you desire. In my case, I use “itsourcecode” as the name of the database.
Then create a table. Put “mydata” as the table name then put the following attributes.
CREATE TABLE `mydata` (`id` int(11) NOT NULL, `name` text NOT NULL, `age` int(11) NOT NULL, `gender` text NOT NULL, `birthday` date NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1;
Now for the connection to the database. Create a “connection.php” file then put the following codes.
<?php
date_default_timezone_set('Asia/Manila');
$servername = 'localhost';
$username = 'root';
$password = '';
$dbname = 'itsourcecode';
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (Exception $ex) {
echo "Connection Failed: ". $ex->getMessage();
}
?>As you can see, we now upgraded our coding structure in managing our database using PDO. This is now the updated version in MYSQL.
Now, create a “index.php” file then put the following codes.
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

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.
