# IoC (Inversion of Control) Module of BlueIgnis

#### Written by Ashwanth Kumar \

#### Version 0.1

## Introduction

An attempt to create a dependency injection for PHP. Current this module independently implements a IoC container (called Registry) for storing all the Services and their corresponding object to service the request which can be injected dynamically. 

## Design Goal:

- Add an Annotation @Inject("ServiceName") to dynamically assign the value of the property or object from our little IoC (Inversion of Control) Registry. 

- Create a Registry of Services, which are loaded and can always be re-used anytime in the code using @Inject("ServiceName")

This module uses [**ARO**](https://github.com/ashwanthkumar/aro-php "Visit ARO project website") in *BlueIgnis* for implementing @Inject style dependency injection. For normal independent usages refer **Usages Example**

##  Usage Examples:

### Add a service to the IoC Container

	// Load the IoC Module

	require_once("/path/to/lib/ioc/IoC.php");

	

	// Create a DB Connection

	$dao = new PDO($dsn, $user, $pass);

	// Get the Registry Instance

	$container = Registry::get();

	$container->addService("DAO", $dao, "DB Connection");	// Valid

	

	// throws ServiceNameAlreadyTakenException Exception

	$container->addService("DAO", new stdClass, "Another sample Object Instance");

 

### Get a particular Service

	// Load the IoC Module

	require_once("/path/to/lib/ioc/IoC.php");

	

	// Get the Registry Instance

	$registry = Registry::get();

	$db = $registry->getService("DAO");	// Valid

	$db = $registry->getService("DoNotExist"); // throws ServiceNotFound Exception

### Get all the services

	// Load the IoC Module

	require_once("/path/to/lib/ioc/IoC.php");

	// Get the Registry Instance

	$registry = Registry::get();

	$service_list = $registry->listAll();

	// Loop through the list of services and display its properties

	foreach($service_list as $service) {

		echo $service['name'] . '\n'; 		// Name of the service

		$obj = $service['object'] . '\n'; 	// Object Instance

		echo $service['description'] . '\n'; // Description of the Service

	}
