Phetit Container
================

[](#phetit-container)

A simple PHP dependency injection container.

This package is an implementation of [PSR-11](https://www.php-fig.org/psr/psr-11/) container interface, and follows the [Semantic Versioning](https://semver.org/spec/v2.0.0.html) specification.

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

[](#installation)

You can install it using [composer](https://getcomposer.org/):

```
composer require phetit/dependency-injection
```

Usage
-----

[](#usage)

Create an instance of `ContainerBuilder` class.

```
use Phetit\DependencyInjection\ContainerBuilder;

$container = new ContainerBuilder();
```

### Register a service

[](#register-a-service)

You can register a service using the `register($id, $resolver)` method, and passing the `id` (string) and the `resolver` (a closure).

```
$container->register('foo', fn() => 'bar');
```

### Retrieving the service

[](#retrieving-the-service)

You can retrieve registered services using the `get($id)` method:

```
$foo = $container->get('foo');
// $foo === 'bar'
```

### Non shared services

[](#non-shared-services)

By default all services are shared. This means that services are resolved only the first time `get($id)` method is called. So in following calls you'll get the same object.

```
$container->register('service', fn() => new Service());

$serviceOne = $container->get('service'); // Service object
$serviceTwo = $container->get('service'); // Service object

// $serviceOne === $serviceTwo => true
```

In order to get a new instance on every call, you need to use the `factory()` method:

```
$container->factory('service', fn() => new Service());

$serviceOne = $container->get('service'); // Service object
$serviceTwo = $container->get('service'); // Service object

// $serviceOne === $serviceTwo => false
```

### Parameters

[](#parameters)

You can register parameters using `parameter()` method:

```
$container->parameter('foo', 'bar');
$container->parameter('closure', fn() => new Service());

$container->get('foo'); // 'bar'

// Parameters are not resolved
$closure = $container->get('closure'); // $closure = fn() => new Service()
$service = $closure(); // 'Service object'
```

### Accessing container from a service

[](#accessing-container-from-a-service)

Container object is injected to service resolvers, so you can access other entries defined in the container:

```
$container->parameter('db_dns', 'mysql:dbname=testdb;host=127.0.0.1');
$container->parameter('db_user', 'dbuser');
$container->parameter('db_pass', 'dbpass');

$container->register('db', fn(Container $c) => new PDO(
    $c->get('db_dns'),
    $c->get('db_user'),
    $c->get('db_pass'),
));
```
