Castel

Castel is a fast Dependency Injection Container. The class for PHP 5.3 consists of just one file.

Installing

Pick up the src/Castel.php file or install it with Composer :

{
    "require": {
        "regeda/castel": "0.1.*"
    }
}

Creating a container is a matter of instating the Castel class

$container = new Castel();

Defining parameters

$container->share('foo', 'bar');
$container->share('something', new Something());

Retrieving parameters as plain properties:

$container->foo; // bar
$container->something; // instance of Something class

Defining services

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

$container->share('session', function () {
    return new Session();
});

Using the defined services

$session = $container->session; // instance of Session class

Extending services after creation

$container->share('mail', function () {
    return new \Zend_Mail();
});
$container->extend('mail', function ($mail, $container) {
    $mail->setFrom($container->getValue('mail.default_from'));
    return $mail;
});
