PHP 8.3 New Features

php 8.3 new features

PHP, the server-side scripting language that has been the backbone of web development for years, continues to evolve. With the release of PHP 8.1 in 2021, the community was thrilled with the new features and improvements. But what about 2023? Let’s dive into the latest releases and explore the exciting new capabilities that are shaping the future of PHP.

PHP 8.2: A New Era of Performance and Security

1. Enumerations (Enums)

PHP 8.2 introduces Enumerations, a feature that allows you to define a set of named values. Enums can be used to create a set of constants for values that are part of a specific group.

enum Status: string {
case DRAFT = 'draft';
case PUBLISHED = 'published';
case ARCHIVED = 'archived';

function publish(Status $status): void {
// ...


2. First-Class Callable Syntax

This feature simplifies the syntax for referencing callables, making the code more readable and concise.

class MyClass {
public function myMethod() {
// ...

$instance = new MyClass();

// Old way
$callable = [$instance, 'myMethod'];

// New way with PHP 8.2
$callable = $instance->myMethod(...);

3. Deprecation of Dynamic Properties

In PHP 8.2, dynamic properties (properties that are not declared but accessed as if they exist) are deprecated. This change promotes better coding practices and reduces potential errors.

class MyClass {}

$instance = new MyClass();
$instance->newProperty = 'value'; // Deprecated in PHP 8.2

4. Enhanced Performance and JIT Compiler

PHP 8.2 continues to focus on performance improvements, including enhancements to the Just-In-Time (JIT) compiler. These changes make PHP faster and more efficient, particularly for large-scale applications.

PHP 8.3: A Sneak Peek

While PHP 8.3 is still in the planning stage, some exciting proposals are on the horizon. These include:

  • Array Unpacking Enhancements: Improving the syntax for array unpacking, making it more flexible and powerful.
  • Readonly Properties: Introducing read-only properties that can only be initialized once, enhancing immutability in classes.


PHP’s latest releases are a testament to the language’s commitment to innovation, performance, and security. With features like Enums, first-class callable syntax, and ongoing performance enhancements, PHP continues to be a robust choice for web developers.

The future of PHP looks bright, and the community eagerly awaits what’s next. Whether you’re a seasoned PHP developer or just starting, now is an exciting time to be part of this ever-evolving language.
