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:

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. Collections with of the most popular applications of generics is collections. This approach was popularized by static analysis tools such as Psalm and PHPStan. In this release, we are adding basic support for generics via PHPDoc annotations.
