PSG SR 4 Flexible Layered DI App Standard
=========================================

[](#psg-sr-4-flexible-layered-di-app-standard)

PHP is a language of flexibilty. Why shouldn't our apps be based on a flexible standard - make the framework account for flexibility, and allow the users to have flexibility in the code they write.

By this standard:

- wares shall have a `process` method
- wares (middle, front, back, ...) shall expect injected dependencies into both `__construct` and `process`
- For HTTP Apps:
    - framework shall allow injection for all Sr1 factories and `Pgs\Sr1\ResponseInterface`, `Pgs\Sr1\ServerRequestInterface`, `Pgs\Sr4\ExitResponseInterface`
    - output of wares can include, not limited to, `Pgs\Sr1\ResponseInterface`, `Pgs\Sr1\ServerRequestInterface`, `Pgs\Sr4\ExitResponseInterface`
        - framework shall integrated these into the response and request
- framework shall implement
    - ->get() for retrieving a named service
    - ->set() for adding a named service
    - ->call() for calling something with dependency injection. This can include constructing a class, by providing just the class name.
    - ->data() for retrieving and setting data
        - ->data(key): retrieve
        - ->data(key, value): set

Because interfaces do not allow defining only the presense of a method, the fulfillment of the standard is left up to the programmer (a method defined with no arguments in an interface then requires implementers to make all arguments optional).

Flow

See [SR-2](https://github.com/PHP-SG/sr-2)

SR 2 Variances
--------------

[](#sr-2-variances)

- the parameters and returns are not specified in the interface. This is to allow the framework to accept a variety of returns, including PSR 7 an SR-1 returns, and then integrate those returns
- Coreware now has an interface. It can still be injected as a closure
- Corewars array. It is now possible to have multiple corewares.
    - if you want to remove all coreware:

```
$App->remove(Coreware::class)
```
