SilexPhpDi
==========

[](#silexphpdi)

Silex Service Provider for the [PHP-DI](http://php-di.org) Dependency Injection Container. It does not replace Silex's default DI container Pimple, but rather adds the extra functionality PHP-DI offers.

Installation
------------

[](#installation)

This library is available on [Packagist](https://packagist.org/packages/thispagecannotbefound/silex-php-di). To include it using Composer, add the following to your `composer.json`:

```
"require": {
	"thispagecannotbefound/silex-php-di": "*"
}

```

Registering
-----------

[](#registering)

Assuming `$app` is a Silex Application instance:

```
$app->register(new ThisPageCannotBeFound\Silex\Provider\PhpDiServiceProvider(), array(
	'di.definitions' => '/path/to/config.php',
));

```

Parameters
----------

[](#parameters)

The following parameters are available. Non are required.

- `di.definitions`: (array of) path(s) of your PHP-DI injection definitions.
- `di.options`: array of options:
    - `cache`: Enables the use of a cache for the definitions. Must be a `Doctrine\Common\Cache\Cache` instance. Defaults to `null`.
    - `container_class`: Name of the container class, used to create the DI container. Defaults to `DI\Container`.
    - `useAnnotations`: Enable or disable the use of annotations to guess injections. Defaults to `true`.
    - `useAutowiring`: Enable or disable the use of autowiring to guess injections. Defaults to `true`.
    - `writeProxiesToFile`: If true, write the proxies to disk to improve performances. Defaults to `false`.
    - `proxyDirectory`: Directory where to write the proxies. Defaults to `null`.
    - `silexAliases`: Add aliases for common Silex services. Defaults to `true`. (see below)
    - `injectOnControllers`: Fulfill controller dependencies after it has been resolved. Defaults to `true`. (see below)

Please refer to [the official documentation](http://php-di.org/doc/container-configuration.html) for more information on container configuration.

### `silexAliases`

[](#silexaliases)

This adds aliases for some common Silex service providers, for example:

```
return array (
	'Doctrine\DBAL\Connection' => \DI\link('db'),
);

```

This means that when your class requests a `Doctrine\DBAL\Connection` injection, it will get the same value as when requesting `$app['db']`, which is the default defined in Silex's `DoctrineServiceProvider`.

### `injectOnControllers`

[](#injectoncontrollers)

If you organize your controllers in classes, enabling this option will fulfill the dependencies of your controller instance. This is achieved by replacing the default Silex controller resolver with this provider's `PhpDiControllerResolver`.

Services
--------

[](#services)

The provider exposes the following services:

- `di`: The dependency injection container, instance of Acclimate's `CompositeContainer`. (see "Acclimate" section below)
- `di.raw`: Instance of the wrapped `DI\Container` instance. (see "Acclimate" section below)
- `di.builder`: The `DI\ContainerBuilder` instance, allowing you to further configure or replace the builder.

Acclimate (container interoperability)
--------------------------------------

[](#acclimate-container-interoperability)

This Service Provider uses [Acclimate](https://github.com/jeremeamia/acclimate-container), as suggested by [the PHP-DI docs](http://php-di.org/doc/container-configuration.html), to allow for PHP-DI and Silex's Pimple to work together. This is manifested through Acclimate's `CompositeContainer`. The way it is configured will make values defined by PHP-DI have a higher priority. Consider the following:

```
