Dutu

Dutu Dependency Injection (DI) container is a small PHP container for PHP 5.3.x developed as part of Dutu Core (core libraries for the upcoming Dutu framework). Dutu (DI) or simply Dutu (not to be confused with the Dutu framework for which it is meant for), influenced by Fabien Pontencier's Pimple, was designed to be intuitive, scalable and flexible.

To use Dutu download it and require it in your code:

require_once '/path/to/Dutu.php';

and then create the container by instantiating the Dutu class:

$dutu = new Dutu();

Defining Parameters

It is as easy as abc. This is how we do it:

$dutu->cookie_name = 'SESSION_ID';

Defining Services

There are two ways to define services in dutu. The first method involves passing an associative array to Dutu's __construct method during instantiation:

//a list of database services
$parameters = array(
    'pdoImpl' => 'PDOImpl',
    'mysqliImpl' => 'mysqliImpl'
);

Then passing the array to the container:

$dutu = Dutu($parameters);

//instantiates your database class
$dutu->pdoImpl;

The second method involves passing an associative array of services to Dutu's registerComponents method:

$dutu->registerComponents($components);

or we can register components with their dependencies too:

//only works if all the components in the array
//have a common dependency
$dutu->registerComponents($components, $dutu->config);
