FlameCore Container

This library provides a simple and lightweight Dependency Injection Container.

Features

• Interfaces: Extended container interfaces compatible with PSR-11

  • ModifiableContainerInterface exposes methods to write and remove container entries.

  • DefinableContainerInterface exposes methods to define container entries.

  • FactoryContainerInterface exposes a method to create new object instances from a factory entry.

  • LockableContainerInterface exposes methods to lock and unlock container entries.

• Classes: Advanced and feature-complete container implementations based on the interfaces

  • Container implements common features like defining, writing, instantiating and removing container entries.

  • LockableContainer extends the above container to enable locking and unlocking of container entries.

Usage

To make use of the API, include the vendor autoloader and use the classes:

namespace Acme\MyApplication;

use FlameCore\Container\Container;

$container = new Container();

You can use get() and has() on the container as usual. You can also set() and remove() entries.

$container->set('foo', new Configuration(...));
if ($container->has('foo')) {
    $value = $container->get('foo'); // Returns Acme\MyApplication\Configuration object
    $container->remove('foo');
}

You can also use object factories:

$container->set('bar', function () {
    return new Configuration(...);
});
$value2 = $container->get('bar'); // Returns Acme\MyApplication\Configuration object

You can also get a fallback value if an entry is not set:

$value3 = $container->getOr('foobar', function () {
    return new Fallback(...);
}); // Returns Acme\MyApplication\Fallback object
