How to Define Non Shared Services

In the service container, all services are shared by default. This means that each time you retrieve the service, you'll get the same instance. This is often the behavior you want, but in some cases, you might want to always get a new instance.

In order to always get a new instance, set the shared setting to false in your service definition:

  • YAML
  • XML
  • PHP

# app/config/services.yml
services:
    app.some_not_shared_service:
        class: ...
        shared: false
        # ...

Now, whenever you call $container->get('app.some_not_shared_service') or inject this service, you'll receive a new instance.
