WI-61497 Generics template should inherit annotations from the interface WI-61438 Support inference based on IteratorAggregate WI-56034 Support the use of generics on classes There are a few known features missing that we’re planning to add in future updates: We will continue to introduce support for generics step-by-step. In fact, if you use the new operator to instantiate an object from a parameter, then there is no need to add a annotation – it’ll just work out of the box: What is the future scope? If you annotate a parameter with a tag, PhpStorm will provide you with the appropriate type inference: With such code, it is common to pass a class name string as an argument and receive an object as a result. application of generics is containers and factories. Nested generics like Base> are not supported, and will likely not be supported in the future, because of the performance overhead. For such annotations, PhpStorm will understand the T types. Type inference and completion are only available for first-level generics in PhpStorm, i.e. Make sure to watch the ticket WI-61438 so you receive notifications about new changes. Iterating over the Doctrine’s Collection interface will be supported in the next update. With Doctrine Collections, you can already get code completion in simple scenarios: Here is a simple example of the annotated collection class: In short, you get more bug-free code and better code completion. Check out the Generics and why we need them post by Brent Roose to learn more about the advantages of this approach over arrays. In PhpStorm 2021.2, you can use generic class collections. This approach was popularized by static analysis tools such as Psalm and PHPStan.Ĭollections with of the most popular applications of generics is collections. In this release, we are adding basic support for generics via PHPDoc annotations. Read this blog post for details about all the significant updates, demonstrated through a ton of GIFs! PHP Support for genericsĪlthough generics is one of the most requested features for the PHP language according to the JetBrains Developer Ecosystem survey, there are no plans to add them any time soon. Here are the main highlights of the release:Īutomatic clean-up of caches and log directories This major release introduces preliminary support for generics in PHP, enums for PHP 8.1, one-line array shapes, improved automatic formatting of PHP code, new inspections and refactorings, and much more.
