PhpStorm 2021.3 will support them all and will help make your code compatible. There are plenty of other changes in the upcoming PHP 8.1. But in PHP 8.1, they are not final by default. Note that in PHP 8.0 and earlier versions, constants in interfaces were implicitly final and you could not directly change them. In PHP 8.1 it will be possible to declare final class constants, so that they cannot be overridden in child classes. It’s great that this is a language feature now! This type improves code analysis, and it’s pretty much the same thing that the # attribute has been doing in PhpStorm.

In PHP 8.1 a new type for return values will be available: never.Ī function or method declared with the never type indicates that it will not return a value and will either throw an exception or end the script’s execution with a call of die(), exit(), trigger_error(), or something similar.

Those will also be supported in PhpStorm 2021.3, and if you decide to upgrade to PHP 8.1, you can add a native type declaration: In older PHP versions it was quite common to use intersection types in PHPDoc annotations. The feature is called pure intersection types because combinations with union types are not supported and are being left for future consideration. In PhpStorm 2021.3, code completion for this will be pretty much the same as it is for union types, because a union can contain members of all involved types, and an intersection must contain members of all types. The syntax is TypeA&TypeB, and it means that the variable must be both instanceof TypeA and instanceof TypeB. Union types were added in PHP 8.0, and now PHP 8.1 is introducing intersection types. PhpStorm has an Alt+Enter quick-fix for this: That is, its internal state can still be changed.Ī readonly property cannot have a default value, but you can initialize it in the constructor as a promoted property. If a readonly property is initialized by an object, it does not become immutable. Properties with the readonly flag must be typed, but if you don’t know the specific type then you can use the mixed type. This means you can assign a value either in the declaration itself or in a class method. You could achieve similar behavior in previous versions of PHP with a private setter, but the readonly keyword makes classes cleaner and constraints stricter.Ī readonly property can be initialized only in the same scope where it’s declared. Readonly properties are properties that cannot be changed after initialization, i.e. You can switch from the toolbar or by specifying the requirement in composer.json.

Let’s go through the features that await you in the upcoming version of PhpStorm.Īs usual, you can try new features by setting the project language level to PHP 8.1. The PHP 8.1 RC 2 has been shipped, so the list of changes is now final.

We started to roll out support for PHP 8.1 back in the last major release – PhpStorm 2021.2 came with full support for enums. With that said, let’s take a look at the first portion of the updates in the upcoming 2021.3 release. Follow us on Twitter at and be among the first to get each new post. Join the Early Access Program to be among the first to try out the updates, share your feedback, and influence the development of PhpStorm.Īlong with the build, every week we will publish a post with a story about new features and changes every week. The third major release of PhpStorm this year will bring full support for all PHP 8.1 features, more enhancements for generics, rsync support, other improvements for deployment, a bunch of new inspections, improved refactorings, and a whole lot more. Today we’re starting the Early Access Program (EAP) for PhpStorm 2021.3.
