New Features, Deprecations, and Bug Fixes in PHP 8.2

PHP 8.2 is rapidly approaching. It is scheduled to go live on December 8th.

PHP 8.2 is solely intended to make the lives of developers easier. The majority of the modifications streamline the coding process and phase out some of the older features. To maximise your site’s security and get acquainted to the new syntax, it’s always a good idea to upgrade to the most recent PHP version.

Let’s take a look at all of the improvements that PHP 8.2 brings to the table so you can decide whether it’s worth switching when the new version is released.

PHP 8.2 Enhancements
In this section, we’ll go over the PHP 8.2 updates and new features.

New classes that are read-only
Version 8.1 introduced the new readonly class property. PHP 8.2 improves on it much more. You can now designate an entire class as readonly. This will make all of the properties of that class read-only. This will not work for dynamic properties; setting them to readonly will result in an error.

Allow true, null, and false to be used as Standalone Types
Users were introduced to Union Types support in PHP 8.0. A type can be declared as a union of two or more types. Although false and null might be used as potential types, they could not be used as standalone types.

False and null will be available as standalone types in PHP 8.2. With this innovation, the PHP type system will be more descriptive, since you will be able to describe return, argument, and property types more precisely.
