Frequently Asked Questions
How does this PHP login or registration system work?
User signup form (with email verification optional), password hashing via password_hash() / password_verify(), login form with session_start(), remember-me cookie, logout, password reset via emailed token.
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?
