The service container provided by the DependencyInjection component allows you to configure the creation of objects. However, sometimes you need to apply the factory design pattern to delegate the object creation to some special object called "the factory". In Symfony 6.1 we're improving the service container to allow you to use expressions as service factories. This can help you in advanced cases such as selecting the factory based on the value of an environment variable. The syntax to use depends on the configuration format: in YAML: factory: '@=service("foo").bar()' in XML: in PHP: ->factory(expr('service("foo").bar()')) The following example shows how to select the factory to use based on the value of a configuration parameter:
# config/services.yamlservices: App\Mailer: factory: "@=parameter('some_param') ? service('some_service') : arg(0)" arguments:
- '@some_other_service'
The arg() function returns the value of arguments passed to the factory (e.g. arg(0) returns the first argument, arg(1) returns the second argument, etc.)
