PHP в 2025 году: что нового? Часть 1 — обзор ключевых изменений

PHP is one of the most popular languages for web development, which continues to actively evolve. In 2025, the programming community expects several significant innovations that will make PHP even more powerful and convenient for learning and professional work. In this first part of the article, we will look at the main changes that have already been implemented or are in active development. If you are just starting to learn PHP for beginners, this information will help you stay up to date with modern trends.

Why does PHP remain relevant in 2025?

Despite the emergence of new languages and frameworks, PHP maintains its leading position in web programming. According to W3Techs, more than 77% of all websites use PHP on the server side. In 2025, the language focuses on performance, security, and developer convenience. Learning PHP today is an investment in a stable and in-demand career.

• Improved performance — JIT compilation has become even more efficient.
• New syntactic capabilities — code becomes cleaner and shorter.
• Enhanced security — built-in tools for protection against attacks.
• Better support for modern standards — JSON, asynchrony, typing.

Main innovations of PHP 8.x and 9.0 (preliminary overview)

Although PHP 9.0 is expected no earlier than 2026, improvements in versions 8.3 and 8.4 are being actively implemented in 2025. Let's look at the key ones.

1. Attributes have become even more powerful

Attributes (annotations), introduced in PHP 8.0, now support nesting and more complex scenarios. This simplifies metaprogramming and makes code more declarative.

<?php

#[Route('/api/users')]#[Middleware('auth')]class UserController {    #[Get('/{id}')]    public function show(int $id): array {        // logic    }}

2. Improved typing and readonly properties

In PHP 2025, readonly properties can be used in interfaces and traits. This increases data security and reduces the number of errors.

<?php

readonly class Config {    public function __construct(        public string $host,        public int $port    ) {}}

$config = new Config('localhost', 8080);// $config->port = 9090; // Error: readonly property

3. Asynchrony without third-party libraries

Previously, asynchronous programming in PHP required extensions (e.g., Swoole or ReactPHP). In 2025, support for async and await has been added to the language core, making working with non-blocking operations extremely simple.

<?php

async function fetchUserData(int $id): array {    $response = await Http::get("/api/users/{$id}");    return $response->json();}

$user = await fetchUserData(42);

New tools for learning PHP in 2025

Learning PHP has become more accessible thanks to new online platforms and built-in language capabilities. Now even PHP for beginners includes interactive tutorials right in the documentation.

• PHP Playground — built-in environment for testing code in the browser.
• Improved static analyzer — finds errors at the code writing stage.
• Integration with Composer 3.0 — simplifies dependency management.

Security: what has changed?

In 2025, PHP pays special attention to web application security. New functions for working with passwords have been added, and protection against XSS and SQL injections has been improved.

<?php

// New way of hashing passwords$hash = password_hash('my_password', PASSWORD_ARGON2ID);

// Verification with automatic rehashingif (pa
