To instantiate autowired services in Symfony, you can follow these steps:

  1. Create a new class or service that you want to instantiate.
  2. Add the @Autowired annotation on top of the class or service declaration. This annotation tells Symfony to automatically inject the required dependencies.
  3. In the controller or another service where you want to use the autowired service, simply include it as an argument in the constructor or as a method parameter.


Here is an example:

use SymfonyComponentDependencyInjectionAttributeAutowired;

class MyService
{
    #[Autowired]
    private OtherService $otherService;

    public function doSomething(): void
    {
        // Use the injected service
        $this->otherService->doAnotherThing();
    }
}


In the above example, OtherService is autowired and injected into MyService using the #[Autowired] attribute.


Note: Make sure you have the Symfony DependencyInjection and Annotations components installed in your project for autowiring to work.
