Simple dependency injection container for PHP
=============================================

[](#simple-dependency-injection-container-for-php)

*There are many dependency injection containers out there, this one is minimalistic and straight forward. Doesn't have any third-party dependencies.*

[![Build Status](https://camo.githubusercontent.com/a1d604f887f1d93d60dc609f38fad243d9d4c06ff1cace9d68668df4cc45ce52/68747470733a2f2f7472617669732d63692e6f72672f7468656f72782f736469632e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/theorx/sdic)

### Dependency registration usage

[](#dependency-registration-usage)

```
$container = new \Theorx\SDIC\SDIC();

//Register single dependency
$container->register(DependencyClassInterface::class, function(Theorx\SDIC\SDIC $container) {

    return new DependencyClass($container->get(DependencyClassDependency::class));
});
```

*Register shared dependency ( Singleton wrapper )*

```
$container->register(DependencyClassInterface::class, function(Theorx\SDIC\SDIC $container) {

    return $container->shared(DependencyClassInterface::class, function() {
        return new DependencyClass();
    });
});
```

*Register array of dependencies*

```
$container->registerArray([
    DependencyAInterface::class => function(){
        return new DependencyA();
    },
    DependencyBInterface::class => function (){
        return new DependencyB();
    }
]);
```

*You can check whether container contains dependency by name using **has** method*

```
if($container->has(DependencyAInterface::class)){
    //has dependency
}
```

*Getting dependencies from the container using **get** method*

```
$instance = $container->get(DependencyBInterface::class);
```

### Container extension

[](#container-extension)

*Container extensions are meant to be used for adding dependencies to the container**Container extensions must implement `SDICExtension` interface which requires you to implement single method for defining array of dependencies*

### Example extension

[](#example-extension)

```
/**
 * Class ExampleExtension
 */
class ExampleExtension implements \Theorx\SDIC\Interfaces\SDICExtension {

    /**
     * @return array
     */
    public function registerDependencies() : array {

        return [
            DependencyDInterface::class => function() {

                return new DependencyD();
            },
            DependencyEInterface::class => function() {

                return new DependencyE();
            }
            //...
        ];
    }
}
```

### Loading container extension / extensions

[](#loading-container-extension--extensions)

*Method `loadExtension` loads extension to the container and registers new dependencies*

```
$container->loadExtension(new ExampleExtension);
```

*For loading multiple extensions there is method `loadExtensions` which accepts array of objects which implement `SDICExtension` interface*
