What you’ll learn in the PHP tutorial series
Beginner basics: variables, arrays, conditionals, loops, functions
Form handling: GET/POST processing, validation, sanitization
MySQL database integration: connecting, querying, prepared statements (PDO + mysqli)
Sessions and authentication: login systems, password hashing with bcrypt

Why PHP is still the #1 BSIT capstone language
In the Philippines, PHP + MySQL remains the most defensible capstone stack: (1) universal hosting: every cPanel shared host supports it, (2) panels are familiar with PHP code patterns, (3) massive open-source ecosystem including WordPress, Laravel, and Symfony, (4) easy deployment from local XAMPP to live shared hosting. PHP 8.x has modern features (named arguments, enums, readonly properties) that match newer languages.
Recommended PHP development setup
XAMPP or Laragon: local PHP + MySQL + Apache stack (free)
PHP 8.2+ (current stable as of 2026)
VS Code with PHP Intelephense extension
Composer for package management
Postman or Insomnia for API testing
phpMyAdmin for database GUI (bundled with XAMPP)

Frequently Asked Questions
Is PHP still relevant in 2026?
Yes, extremely relevant. PHP still powers around 75-80% of websites with server-side code, including WordPress, Wikipedia, Slack admin tools, and most Philippine BSIT capstones. Modern PHP 8.x has features comparable to other modern languages (named arguments, enums, readonly properties, JIT compilation). For BSIT defense, PHP is one of the safest, most-defendable choices because panels are deeply familiar with it.
Which PHP version should I use?
Use PHP 8.2 or newer (8.3 is the current stable as of 2026). PHP 5.x and 7.x are end-of-life and pose security risks. Most Philippine shared hosting providers offer PHP 8.x in cPanel, just switch via PHP Selector. Older capstones using
mysql_* functions need 2-3 small patches to mysqli or PDO for PHP 8 compatibility.What's the difference between PHP, Laravel, and CodeIgniter?
PHP is the language itself. Laravel and CodeIgniter are frameworks written in PHP that give you structure (routing, ORM, auth, templating). Laravel is modern, feature-rich, with the largest community, best for new capstones. CodeIgniter is lightweight, fast, easier to learn, good for smaller projects or when your panel prefers traditional MVC. Pure PHP (no framework) still works for simple capstones but lacks structure.
How do I set up a local PHP development environment?
Easiest options: XAMPP (Apache + MySQL + PHP, free, cross-platform, the standard for Philippine BSIT) or Laragon (Windows-only, cleaner UI, hot-swap PHP versions, includes Nginx). Both give you
localhost/your-project in minutes. Pair with VS Code + Intelephense extension for the best free PHP IDE experience.How do I connect PHP to MySQL safely?
Use PDO (PHP Data Objects) with prepared statements, it's the modern, secure standard. Never concatenate user input into SQL strings (SQL injection risk). Example:
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = ?"); $stmt->execute([$user_id]);. Prepared statements + parameter binding = SQL injection prevention by design. The mysqli extension also supports prepared statements if you prefer it over PDO.What can I build with PHP for my capstone?
Common Philippine BSIT capstone domains using PHP + MySQL: Management systems (Library, Hospital, Hotel, Restaurant, Inventory, Payroll, School), E-commerce (shopping cart, online store), Booking systems (Hotel, Restaurant, Airline, Bus), Educational platforms (online quiz, LMS), Service appointment systems (clinic, salon).
