Installing
----------

[](#installing)

### Installing via Composer

[](#installing-via-composer)

Append the lib to your requirements key in your composer.json.

```
{
    // composer.json
    // [..]
    require: {
        // append this line to your requirements
        "nurse/di": "dev-master"
    }
}
```

For PHP 5.3 and 5.4 support use version 0.9.2.

### Alternative install

[](#alternative-install)

- Learn [composer](https://getcomposer.org). You should not be looking for an alternative install. It is worth the time. Trust me ;-)
- Follow [this set of instructions](#installing-via-composer)

Usage
-----

[](#usage)

Defining a dependency:

```
$container = new Nurse\Container;

// Defining a dependency

$container->set('connection', function ($container) {
    $params = $container->get('connection_params');
    return new Connection($params);
})
->set('connection_params', function () {
    return array(
        'schema'   => 'someschema',
        'username' => 'root',
        'password' => 's3cr3t',
    );
});

// Retrieving the dependency (lazy loading)
$connection = $container->get('connection');

// alternatively you can use the singleton instance of the container

Nurse\Di::set('connection', function ($container) {
    $params = $container->get('connection_params');
    return new Connection($params);
})
->set('connection_params', function () {
    return array(
        'schema'   => 'someschema',
        'username' => 'root',
        'password' => 's3cr3t',
    );
});

$connection = Nurse\Di::get('connection');
```

You can also create factories:
