config VS di

Now we understand how to do any configuration of any YiiFramework package or external, it is not necessary to have a single long and complex configuration file, we can organize it according to the group of configurations and Yii config will do the work for you, as well as the container it applies the definitions for you, with the automatic wiring facility in controllers, which makes it easy to access any container dependency without the need to use static access to it, or depend on the container itself.

Now we are going to understand how the definition works inside the .php file, the first thing we do is define the class to configure in our container di, in this case ApplicationParameters::class, the other thing we observe is a comment /** @ var array $params */, here we can see the magic of Yii Config, it automatically allows you to access the parameters defined in the params group, and thus be able to use them in the configuration.

Yii Config 1.0.0

The language is not that important, if you know Php, you learn another one in weeks (not you, Rust!) important and source of income is the knowledge of Design patterns and for what implementation to use which specific Pattern. PHP have a great ecosystem regarding design patterns. As there are the psr. Mostly, the Frameworks implement these recommendations: - dependency injection in Symfony, yii and spiral - Data Mapper implemented in doctrine or in cycle-orm.

Version released.

Now that we are clear about the concepts of configuration, container di and factory, let's see the complexity of creating an app.

Using the container di: Usage of the container di is fairly simple: You first initialize it with an array of definitions. The array keys are usually interface names. It will then use these definitions to create an object whenever that type is requested. This happens for example when fetching a type directly from the container somewhere in the application. But objects are also created implicitly if a definition has a dependency to another definition.

Now that we understand the concept in our next post, we will fully describe our configurations, and explain in detail the use of the container di and the factory.
