A simple dependency injection container for php projects

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

[](#installation)

```
composer require njeaner/di-container
```

How to use it
-------------

[](#how-to-use-it)

### Container Initialization

[](#container-initialization)

#### Initialize without parameter

[](#initialize-without-parameter)

```
$container = new \NJContainer\Container\Container();
```

#### Initialize using the parameter

[](#initialize-using-the-parameter)

The container can be constructed with:

- @param **\\NJContainer\\Container\\InstanceDefinition|null** $instance

and **NJContainer\\Container\\InstanceDefinition** can be constructed with:

- @param **\\NJContainer\\Container\\ContainerDefinition|null**

```
$containerDefinition = new \NJContainer\Container\ContainerDefinition();

$instance = new \NJContainer\Container\InstanceDefinition();
// or
$instance = new \NJContainer\Container\InstanceDefinition($containerDefinition);

$container = new \NJContainer\Container\Container($instance);
```

### Setting a dependency in the container

[](#setting-a-dependency-in-the-container)

Setting one definition

```
/**
 * @param id string
 * @param mixed $definition
 * @param bool $shared, if "true" container will save this definition instance as a factory dependency
*/
$container->set($id, $definition)
$container->set($id, $definition, true)
```

Setting several definition using an array of definitions

```
/**
 * @param  $definitions
 * @example [
 *      'name'=> ['John Doe'],
 *      'stdClass1'  => [new stdClass()],
 *      \Namespace\Route::class => [new \Namespace\Route(), true]
 * ];
 * The true value as second item in dependency array means that you are storing an= factory dependency
*/
$container->add($definitions)
```

Setting several definition using an file with return an array of definitions

```
/**
 * @param string $definitionsPath, path directory of definition file
*/
$container->addDefinition($definitionsPath)
```

### Setting dependency parameters

[](#setting-dependency-parameters)

Setting a parameter of an alias

```
/**
 * @param string $id definition id
 * @param string $name parameter name
 * @param mixed $parameter param value to set in definition
*/
$container->setParameter($id, $name, $parameter)
```

Setting several parameter of an alias

```
/**
 * @param string $id definition id
 * @param array $parameters
*/
$container->setParameters($id, $parameters)
```

### Getting a dependency from the container

[](#getting-a-dependency-from-the-container)

```
/**
 * @param string $id
 * @param bool $shared, if "true" container with retrieve a factory dependency
*/
$container->get($id)
$container->get($id, true)
```

Use example
-----------

[](#use-example)

```
class Foo{

}

class Bar {
    public function __construct(Foo $foo, $type = 'Bar'){
        $this->foo = $foo;
        $this->type = $type
    }
}

class FooBar{
    public function __construct(Foo $foo , string $name, array $params){

    }
}
```

```

    # dependency configuration file
