PHP 2025 Curriculum: Where to Start for Beginners

PHP remains one of the most in-demand languages for web development. Despite the emergence of new technologies, more than 75% of all websites on the internet run on PHP, including giants like WordPress and Facebook (partially). If you have decided to start learning PHP in 2025, this curriculum will help you create a clear roadmap.

Stage 1: Web Technology Basics (2–3 weeks)

Before writing PHP code, it is important to understand how the web works. Study:

HTTP protocol: GET and POST methods, response statuses.
HTML and CSS: basic tags, forms, page styling.
Client-server architecture: how the browser communicates with the server.

At this stage, do not delve into complex topics — a basic understanding is enough.

Stage 2: PHP Basics (4–6 weeks)

Move on to the language itself. Your goal is to confidently write simple scripts.

Syntax and variables: data types, operators, constants.
Control structures: if/else, switch, for/while/foreach loops.
Functions: declaration, arguments, scopes.
Arrays and strings: basic functions for working with them.
Superglobal arrays: $_GET, $_POST, $_SESSION.

Practice: create a simple feedback form or a guest book.

Stage 3: Databases and SQL (3–4 weeks)

A modern website is impossible without working with data. Study:

MySQL/MariaDB: creating tables, CRUD operations (INSERT, SELECT, UPDATE, DELETE).
PDO: secure database connection from PHP, protection against SQL injection.
Table relationships: JOIN, foreign keys, normalization.

Create a mini-project: a blog with the ability to add and view articles.

Stage 4: Advanced PHP (2–3 weeks)

Deepen your knowledge and learn to write quality code:

OOP (Object-Oriented Programming): classes, inheritance, interfaces, traits.
Error handling: try/catch, exceptions.
Working with files and sessions: file uploads, authentication.

Stage 5: Frameworks and Modern Tools (4–6 weeks)

In 2025, no serious project is written from scratch in pure PHP. Choose one of the frameworks:

Laravel — the most popular framework with a huge community and a convenient ecosystem (Eloquent ORM, Blade, Artisan).
Symfony — more strict and modular, suitable for large enterprise projects.

Also, be sure to get acquainted with Composer (dependency manager) and Git (version control system).
