Before we can implement the interface we need to install its definition with composer `composer require "psr/container:^1.0"`.
|

now we can create a file with a Class that implements that interface.

|
If you take a critical look at the services array you might see that we need to manually define how our Hello- and
|
||||||
|
Other-Action are getting constructed. This is quite repetitive, as we have already declared what objects to create
|
||||||
|
when asking for the ResponseInterface and the Clock-Interface. We would need to write way less code, if our Container
|
||||||
|
was smart enough to automatically figure our which services to Inject by looking at the constructor of a class.
|
||||||
|
|
||||||
|
PHP provides us with the great Reflection Api that is capable of showing us, [what arguments a constructor of any
|
||||||
|
given class requires](https://www.php.net/manual/de/reflectionclass.getconstructor.php]. We could implement that
|
||||||
|
functionality ourselves, or just try to use a library that takes care of that for us.
|
||||||
|
|
||||||
A dependency injector resolves the dependencies of your class and makes sure that the correct objects are injected when
|
You can query the composer database to find all [libraries that implment the container interface](https://packagist.org/providers/psr/container-implementation).
|
||||||
the class is instantiated.
|
|
||||||
|
|
||||||
Again the FIG has defined an [interface](https://www.php-fig.org/psr/psr-11/) for dependency injection that we can work
|
|
||||||
with. Almost all common dependency injection containers implement this interface, so it is a good starting point to look
|
|
||||||
for a [suitable solution on packagist](https://packagist.org/providers/psr/container-implementation).
|
|
||||||
|
|
||||||
I choose the [PHP-DI](https://packagist.org/packages/php-di/php-di) container, as it is easy to configure and provides some very [powerfull features](https://php-di.org/#autowiring)

out of the box, and also solves the autowiring problem.
|
||||||
|
|
||||||
After installing the container through composer create a new file with the name `dependencies.php` in your config folder:
|
Lets rewrite our `container.php` file to use the PHP-DI container and only define the Services the Container cannot
|
||||||
|
automatically build.
|
||||||
|
|
||||||
```php
|
```php
|
||||||
<?php declare(strict_types=1);
|
<?php declare(strict_types=1);
|
||||||
|
|
||||||
$builder = new \DI\ContainerBuilder();
|
|
||||||
|
$builder = new \DI\ContainerBuilder;
|
||||||
|
|
||||||
$builder->addDefinitions([
|
$builder->addDefinitions([
|
||||||
\Psr\Http\Message\ResponseInterface::class => \DI\create(\Laminas\Diactoros\Response::class),
|
|
||||||
\Psr\Http\Message\ServerRequestInterface::class => fn () => \Laminas\Diactoros\ServerRequestFactory::fromGlobals(),
|
\Psr\Http\Message\ServerRequestInterface::class => fn () => \Laminas\Diactoros\ServerRequestFactory::fromGlobals(),
|
||||||
|
\Psr\Http\Message\ResponseInterface::class => fn () => new \Laminas\Diactoros\Response(),
|
||||||
|
\FastRoute\Dispatcher::class => fn () => \FastRoute\simpleDispatcher(require __DIR__ . '/routes.php'),
|
||||||
|
\Lubian\NoFramework\Service\Time\Clock::class => fn () => new \Lubian\NoFramework\Service\Time\SystemClock(),
|
||||||
]);
|
]);
|
||||||
|
|
||||||
return $builder->build();
|
return $builder->build();
|
||||||
```
|
```
|
||||||
|
|
||||||
In this file we create a containerbuilder, add some definitions to it and return the container.
|
As the PHP-DI container that is return by the `$builder->build()` method implements the same container interface as our
|
||||||
As the container supports autowiring we only need to define services where we want to use a specific implementation of
|
previously used ad-hoc container we won't need to update the our Bootstrap file and everything still works.
|
||||||
an interface.
|
|
||||||
|
|
||||||
In the example i used two different ways of defining the service. The first is by using the 'create' method of PHP-DI to
|
|
||||||
tell the container that it should create a Diactoros\Response object when ever I query a ResponseInterface, in the second
|
|
||||||
exampler I choose to write a small factory closure that wraps the Laminas Requestfactory.
|
|
||||||
|
|
||||||
Make sure to read the documentation on definition types on the [PHP-DI website](https://php-di.org/doc/php-definitions.html#definition-types),
|
|
||||||
as we will use that extensively.
|
|
||||||
|
|
||||||
Of course your `Bootstrap.php` will also need to be changed. Before you were setting up `$request` and `$response` with `new` calls. Switch that to the dependency container. We do not need to get the response here, as the container will create and use it internally
|
|
||||||
to create our Handler-Object
|
|
||||||
|
|
||||||
```php
|
|
||||||
$container = require __DIR__ . '/../config/dependencies.php';
|
|
||||||
assert($container instanceof \Psr\Container\ContainerInterface);
|
|
||||||
|
|
||||||
$request = $container->get(\Psr\Http\Message\ServerRequestInterface::class);
|
|
||||||
assert($request instanceof \Psr\Http\Message\ServerRequestInterface);
|
|
||||||
```
|
|
||||||
|
|
||||||
The other part that has to be changed is the dispatching of the route. Before you had the following code:
|
|
||||||
|
|
||||||
```php
|
|
||||||
$className = $routeInfo[1];
|
|
||||||
$handler = new $className($response);
|
|
||||||
assert($handler instanceof \Psr\Http\Server\RequestHandlerInterface)
|
|
||||||
foreach ($routeInfo[2] as $attributeName => $attributeValue) {
|
|
||||||
$request = $request->withAttribute($attributeName, $attributeValue);
|
|
||||||
}
|
|
||||||
$response = $handler->handle($request);
|
|
||||||
```
|
|
||||||
|
|
||||||
Change that to the following:
|
|
||||||
|
|
||||||
```php
|
|
||||||
/** @var RequestHandlerInterface $handler */
|
|
||||||
$className = $routeInfo[1];
|
|
||||||
$handler = $container->get($className);
|
|
||||||
assert($handler instanceof RequestHandlerInterface);
|
|
||||||
foreach ($routeInfo[2] as $attributeName => $attributeValue) {
|
|
||||||
$request = $request->withAttribute($attributeName, $attributeValue);
|
|
||||||
}
|
|
||||||
$response = $handler->handle($request);
|
|
||||||
```
|
|
||||||
|
|
||||||
Make sure to use the container fetch the response object in the catch blocks as well:
|
|
||||||
|
|
||||||
```php
|
|
||||||
} catch (MethodNotAllowed) {
|
|
||||||
$response = $container->get(ResponseInterface::class);
|
|
||||||
assert($response instanceof ResponseInterface);
|
|
||||||
$response = $response->withStatus(405);
|
|
||||||
$response->getBody()->write('Not Allowed');
|
|
||||||
} catch (NotFound) {
|
|
||||||
$response = $container->get(ResponseInterface::class);
|
|
||||||
assert($response instanceof ResponseInterface);
|
|
||||||
$response = $response->withStatus(404);
|
|
||||||
$response->getBody()->write('Not Found');
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Now all your controller constructor dependencies will be automatically resolved with PHP-DI.
|
|
||||||
|
|
||||||
We can now use that to inject all kinds of services. Often we need to work with the Current time to do some comparisons
|
|
||||||
in an application. Of course we are writing S.O.L.I.D. and testable code so that we would never be so crazy as to call
|
|
||||||
`$time = new \DateTimeImmutable();` in our Action directly, because then we would need to change the system time of we
|
|
||||||
want to work with a different date in a test.
|
|
||||||
|
|
||||||
Therefore we are creating a new Namespace called 'Service\Time' where we introduce a Now-Interface and an Implementation
|
|
||||||
that creates us a DateTimeImmutable object with the current date and time.
|
|
||||||
|
|
||||||
src/Service/Time/Now.php:
|
|
||||||
```php
|
|
||||||
namespace Lubian\NoFramework\Service\Time;
|
|
||||||
|
|
||||||
interface Now
|
|
||||||
{
|
|
||||||
public function __invoke(): \DateTimeImmutable;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
src/Service/Time/SystemClockNow.php:
|
|
||||||
```php
|
|
||||||
namespace Lubian\NoFramework\Service\Time;
|
|
||||||
|
|
||||||
final class SystemClockNow implements Now
|
|
||||||
{
|
|
||||||
|
|
||||||
public function __invoke(): \DateTimeImmutable
|
|
||||||
{
|
|
||||||
return new \DateTimeImmutable;
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
If we want to use that Service in our HelloAction we just need to add it as another argument for the Constructor and
|
|
||||||
update the handle-method to use the new class property:
|
|
||||||
|
|
||||||
```php
|
|
||||||
<?php declare(strict_types=1);
|
|
||||||
|
|
||||||
namespace Lubian\NoFramework\Action;
|
|
||||||
|
|
||||||
use Lubian\NoFramework\Service\Time\SystemClockNow;
|
|
||||||
use Psr\Http\Message\ResponseInterface;
|
|
||||||
use Psr\Http\Message\ServerRequestInterface;
|
|
||||||
use Psr\Http\Server\RequestHandlerInterface;
|
|
||||||
|
|
||||||
final class Hello implements RequestHandlerInterface
|
|
||||||
{
|
|
||||||
public function __construct(
|
|
||||||
private ResponseInterface $response,
|
|
||||||
private SystemClockNow $now,
|
|
||||||
)
|
|
||||||
{
|
|
||||||
}
|
|
||||||
|
|
||||||
public function handle(ServerRequestInterface $request): ResponseInterface
|
|
||||||
{
|
|
||||||
$name = $request->getAttribute('name', 'Stranger');
|
|
||||||
$nowAsString = ($this->now)()->format('H:i:s');
|
|
||||||
$body = $this->response->getBody();
|
|
||||||
|
|
||||||
$body->write('Hello ' . $name . '!');
|
|
||||||
$body->write(' The Time is ' . $nowAsString);
|
|
||||||
|
|
||||||
return $this->response
|
|
||||||
->withBody($body)
|
|
||||||
->withStatus(200);
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
If you open the route in your browser you should see that the current time gets displayed. This happens because PHP-DI
|
|
||||||
automatically figures out what classes are requested in the constructor and tries to create the objects needed.
|
|
||||||
|
|
||||||
But we do not want to depend on the SystemClockNow implementation in our class because that would violate our sacred
|
|
||||||
S.O.L.I.D. principles therefore we need to change the Typehint to the Now interface:
|
|
||||||
|
|
||||||
```php
|
|
||||||
public function __construct(
|
|
||||||
private ResponseInterface $response,
|
|
||||||
private Now $now,
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
When we are now accessing the Handler in the Browser we get an Error because we have not defined which implementation
|
|
||||||
should be use to satisfy dependencies on the Now interface. So lets add that definition to our dependencies file:
|
|
||||||
|
|
||||||
```php
|
|
||||||
\Lubian\NoFramework\Service\Time\Now::class => fn () => new \Lubian\NoFramework\Service\Time\SystemClockNow(),
|
|
||||||
```
|
|
||||||
|
|
||||||
we could also use the PHP-DI create method to delegate the object creation to the container implementation:
|
|
||||||
```php
|
|
||||||
\Lubian\NoFramework\Service\Time\Now::class => DI\create(\Lubian\NoFramework\Service\Time\SystemClockNow::class),
|
|
||||||
```
|
|
||||||
|
|
||||||
this way the container can try to resolve any dependencies that the class might have internally, but prefer the other
|
|
||||||
method because we are not depending on this specific dependency injection implementation.
|
|
||||||
|
|
||||||
Either way the container should now be able to correctly resolve the dependency on the Now interfacen when you are
|
|
||||||
requesting the Hello action.
|
|
||||||
|
|
||||||
If you run phpstan now, you will get some errors, because the get method on the ContainerInterface returns 'mixed'. As
|
|
||||||
we will adress these issues later, lets tell phpstan that we know about the issue and we can ignore it for now. This way
|
|
||||||
we wont get any warnings for this particular issue, but for any other issues we add to our code.
|
|
||||||
|
|
||||||
Update the phpstan.neon file to include a "baseline" file:
|
|
||||||
|
|
||||||
```
|
|
||||||
includes:
|
|
||||||
- phpstan-baseline.neon
|
|
||||||
|
|
||||||
parameters:
|
|
||||||
level: 9
|
|
||||||
paths:
|
|
||||||
- src
|
|
||||||
```
|
|
||||||
|
|
||||||
if we run phpstan with './vendor/bin/phpstan analyse --generate-baseline' it will add all current errors to that file and
|
|
||||||
ignore them in the future. You can also add that command to your composer.json for easier access. I have called it just
|
|
||||||
'baseline'
