Embryo Container
================

[](#embryo-container)

Embryo Container is a small and PSR-11 compatible Dependency Injection Container for PHP.

Requirements
------------

[](#requirements)

- PHP >= 7.1

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

[](#installation)

Using Composer:

```
$ composer require davidecesarano/embryo-container

```

Usage
-----

[](#usage)

### Create Service

[](#create-service)

Services are defined by anonymous functions that return an instance of an object:

```
$container = new \Embryo\Container\ContainerBuilder;
$container->set('connection', function(){
    return [
        'host' => 'localhost',
        'db'   => 'database',
        'user' => 'user',
        'pass' => 'pass'
    ];
});

$container->set('pdo', function($container){
    $connection = $container->get('connection');
    $mysql = 'mysql:host='.$connection['host'].';dbname='.$connection['db'], $connection['user'], $connection['pass']);
    return new \PDO($mysql);
});
```

Note that the anonymous function has access to the current container instance.

### Using Service

[](#using-service)

Using the defined services:

```
$pdo = $container->get('pdo');
```

### Automatic Injection

[](#automatic-injection)

Container can automatically create and inject dependencies with Autowiring. Autowiring is enabled by default. You can disable it using the container builder:

```
$container->useAutowiring(false);
```

Autowiring is the ability of the container to automatically create and inject dependencies. Embryo Container uses PHP's reflection to detect what parameters a constructor needs.

```
class Person
{
    public function getName()
    {
        return 'David';
    }
}

class Hello
{
    public $name;

    public function __construct(Person $person)
    {
        $this->name = $person->getName();
    }

    public function getHello()
    {
        return 'Hello '.$this->name;
    }
}

$container = new \Embryo\Container\ContainerBuilder;
$hello = $container->get('Hello');
echo $hello->getHello(); // Hello David
```

In this example, Embryo Container creates a `Person` instance (if it wasn't already created) and pass it as a constructor parameter.

### Service Provider

[](#service-provider)

Embryo Container can defines a service into a provider extending `ServiceProvider` instance:

```
use Embryo\Container\ContainerBuilder;
use Embryo\Container\ServiceProvider;

class TestServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->container->set('testService', function($container){
            $other = $container->get('otherService');
            return 'This is a Test Service! '.$other;
        });
    }
}

$container = new ContainerBuilder;
$test_service_provider = new TestServiceProvider($container);
$test_service_provider->register();
echo $container['testService']; // This is a Test Service!
```

Example
-------

[](#example)

You may quickly test this using the built-in PHP server:

```
$ cd example
$ php -S localhost:8000

```
