php 8.2

Have you wondered what makes one programming language powerful and flexible? The language’s ability to improve with each version. This simplifies code writing.

PHP 8.2 added improvements, optimizations, and time-saving features that changed PHP coding.

What major changes and new features does PHP 8.2 bring? How will they change coding? Learn about PHP 8.2’s new features, updates, and benefits on this blog.

PHP 8.2

PHP 8.2 (released in 2022) will improve PHP’s power, speed, and usability for developers. PHP 8.2 improves the security, speed, and writing of your web assets, helping them run at their best.

The new version emphasizes backward compatibility, so old PHP code can be easily updated. The most important parts of PHP 8.2 are below.

A Closer Look at Some of PHP 8.2’s Key Features

The Type “Enum”

PHP 8.2’s “enum” feature lets developers create a list of named values for code structure and safety. Enums make code easier to read, prevent invalid values, and clarify variable uses.

Only Read Classes

When PHP 8.1 was first released, the read-only properties for classes were meant to give developers a new way to work with class properties. Once set, a property that can only be read stays the same even within the class scope. After this feature was successfully added to PHP 8.1, PHP 8.2 added better read-only classes that let developers declare all class instance properties as read-only, saving them time and typing.

DNF Types of Disjunctive Normal Form

New DNF-type features were added to PHP 8.2. It’s important to note that this improvement lets both Union Types and Intersection Types work together. Disjunctive Normal Form gives a standard way for them to work together that a parser can understand. Developers need to know how to write DNF Types correctly.

The Right DNF Types

  • Null
  • False
  • True as stand-alone values

PHP 8.2 introduced “Standalone types” to simplify type declarations and improve code safety. A variable can hold “null” when “Null” is a type. It ensures that a parameter can be “null,” meaning it has no value.

However, using “false” or “true” as standalone types means a variable can hold a boolean value. It’s crucial when you want to restrict boolean values and use other values.

Why you should upgrade to PHP 8.2?

Better quality code

Better code is made possible by the new and improved features in PHP 8.2. For example, the release of the “enum” type, strict type checking, and better error handling all help to make code bases more stable and easier to maintain.

Better security

New and improved PHP 8.2 features enable better code. The release of the “enum” type, strict type checking, and better error handling make code bases more stable and maintainable.

Quicker Website

PHP 8.2 websites and web apps prioritize business security, reducing security holes. This hinders hackers from exploiting your site. Remember that PHP’s creators no longer support PHP 5.4, 5.5, and 5.6. It simply means no more support or security updates. Why risk having a hackable website or app?


PHP 8.2 benefits developers and business owners in many ways. The latest PHP version protects and improves web assets. Developers also benefit from PHP 8.2’s improved error handling, code quality, performance, and more.

Hire PHP developers are cheap and easy to find. Hiring dedicated PHP developers for your next web application development project can save time and money.
