❗ Basic container implementation with the ability to inject dependencies
PHP >= 8.0.0
Add the latest version of MicroDependencyInjection into your project by using Composer or manually:
Using Composer (Recommended)
Either run the following command in the root directory of your project:
composer require micro/dependency-injection
Or require the Checkout.com package inside the composer.json of your project:
"require": {
"php": ">=8.0",
"micro/dependency-injection": "dev-master"
},
After adding the library to your project, include the file autoload.php found in root of the library.
include 'vendor/autoload.php';use \Micro\Component\DependencyInjection\Container;
class Logger {
}
class Mailer {
public function __construct(private Logger $logger) {}
}
$container = new Container();
$container->register(Logger::class, function(Container $container) {
return new Logger();
});
$container->register(Mailer::class, function(Container $container) {
return new Mailer($container->get(Logger::class));
});
$mailer = $container->get(Mailer::class);interface HelloWorldFacadeInterface
{
public function hello(string $name): string;
}
class HelloWorldFacade implements HelloWorldFacadeInterface
{
public function hello(string $name): string
{
return "Hello, {$name}.";
}
}
class HelloWorldDecorator implements HelloWorldFacadeInterface
{
public function __construct(
private readonly HelloWorldFacadeInterface $decoratedService,
)
{
}
public function hello(string $name): string
{
$result = $this->decoratedService->hello($name);
return $result . ' I\'m glad to see you';
}
}
$container = new Container();
$container->register(HelloWorldFacadeInterface::class, function () {
return new HelloWorldFacade();
});
$container->decorate(HelloWorldFacadeInterface::class, function(
HelloWorldFacadeInterface $serviceForDecoration
) {
return new HelloWorldLoggerAwareDecorator($serviceForDecoration);
});
echo $container->get(HelloWorldFacadeInterface::class)->hello('Stas');
// Output: Hello, Stas. I'm glad to see you
