PHP 2025 Curriculum: Where to Start Learning the Language

PHP remains one of the most in-demand languages for web development. According to the TIOBE index for 2025, PHP is in the top 10 programming languages, and its share of the backend market is over 75%. If you decide to master PHP in 2025, it's important to create the right learning plan to avoid wasting time on outdated technologies.

In this article, we offer a step-by-step curriculum for beginners that will help you master the current versions of PHP 8.3 and 8.4.

Step 1: Basics of Syntax and Basic Constructs

Start by installing PHP and setting up a local server (OpenServer, XAMPP, or Docker). Master the fundamental topics:

• Variables, data types (int, string, float, bool, null)
• Conditional operators (if/else, switch)
• Loops (for, while, foreach)
• Arrays (indexed, associative, multidimensional)
• Functions (declaration, parameters, return)
• Working with forms (GET/POST)

Resource: the official documentation at php.net is the best reference. For practice, use online sandboxes like phptester.net.

Step 2: Working with Databases

Modern web is impossible without databases. Learn:

• MySQL and MariaDB (installation, creating tables)
• SQL queries (SELECT, INSERT, UPDATE, DELETE)
• PDO (PHP Data Objects) — a modern way to work with databases
• Prepared statements (protection against SQL injection)

Write a simple CRUD application (a task list or a blog) — this will solidify your skills.

Step 3: Object-Oriented Programming (OOP)

After mastering the syntax basics, move on to OOP, which is actively used in modern frameworks:

• Classes and objects
• Inheritance, encapsulation, polymorphism
• Abstract classes and interfaces
• Traits (PHP-specific)
• Namespaces

Create a small project with classes — for example, an online store with products, a cart, and orders.

Step 4: Frameworks and Composer

In 2025, no serious project is written from scratch. Learn:

• Composer — the dependency manager for PHP
• Laravel — the most popular framework (65% of the PHP market)
• Alternatives: Symfony, Yii2 (for enterprise projects)

Laravel simplifies routing, database work (Eloquent ORM), and authentication. Take the official Laravel Bootcamp — it's free.

Step 5: Modern Practices and Tools

To become a sought-after developer, add to your toolkit:

• Version control systems (Git, GitHub/GitLab)
• Testing (PHPUnit for unit tests)
• REST API — creation and documentation (Swagger)
• Security (XSS, CSRF, password hashing)
• Caching (Redis, Memcached)

Don't forget about frontend: basic HTML, CSS, and JavaScript will help you understand the frontend.
