Installation

```

Usage

[](#usage)

```
use Elazar\Auryn\Container;
use Acme\SomeDependency;

$container = new Container;

if ($container->has(SomeDependency::class)) {
    // ...
}

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

// All public methods of Auryn\Injector are available
$instance = $container->make(SomeDependency::class);
```

Be sure you are familiar with [how Auryn works](https://github.com/rdlowrey/Auryn#how-it-works). As recommended by its author, avoid using it as a [service locator](https://en.wikipedia.org/wiki/Service_locator_pattern).

Implementation
--------------

[](#implementation)

While I agree with a lot of the discussion in [this issue](https://github.com/rdlowrey/Auryn/issues/77)regarding why new projects can use Auryn directly without a *PSR-11*implementation, I do think that such an implementation can be useful for integrating Auryn with third-party libraries that use *PSR-11*, such as [zend-expressive](https://github.com/zendframework/zend-expressive).

The implementation in this repository takes a small amount of liberty with this passage from [Section 1.1.2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-11-container.md#112-reading-from-a-container)of the *PSR-11* specification:

> `has` ... MUST return `true` if an entry identifier is known to the container

Auryn uses [fully qualified names](https://en.wikipedia.org/wiki/Fully_qualified_name)for classes and interfaces to identify dependencies where most container implementations use user-designated names. As such, it's possible for Auryn to instantiate a class even if it contains no definitions for that class (e.g. if the class has no required constructor parameters or if those parameters are themselves instantiable classes).

Because of this, `ContainerInterface->has()` in this *PSR-11*implementation will return `true` if either the underlying `Auryn\Injector`instance has definitions for a requested class or interface or if a requested class is defined and considered instantiable (i.e. is not `abstract` and has a `public` implementation of `__construct()`). While some may view this as technically incorrect, it seems consistent to me with the overall spirit and intentions of the *PSR-11* standard.

Development

To run the PHPUnit test suite:

```
composer run-script test
