Requirements

  • PHP 7.4 or higher.

Installation

The package could be installed with composer:

composer require yiisoft/definitions --prefer-dist

General usage

The factory is useful if you need to create objects using definition syntax and/or want to configure defaults for objects created.

$container = new PSR11DependencyInjectionContainer();
$factoryConfig = [
    EngineInterface::class => [
        'class' => EngineMarkOne::class,
        '__construct()' => [
            'power' => 42,
        ],
    ]
];

$factory = new Factory($container, $factoryConfig);

$one = $factory->create(EngineInterface::class);
$two = $factory->create([
    'class' => EngineInterface::class,
    '__construct()' => [
        'power' => 146,
    ],
]);

In the code above we define factory config specifying that when we need EngineInterface, an instance of EngineMarkOne will be created with power constructor argument equals to 42. We also specify that all the dependencies requested by the object created should be resolved by PSR11DependencyInjectionContainer.

First call to create() uses default configuration of EngineInterface as is. Second call specifies custom configuration for power constructor argument. In this case, configuration specified is merged with default configuration overriding its keys when the key name is the same.

Tuning for production

By default, the factory validates definitions right when they are set. In production environment, it makes sense to turn it off by passing false as a third constructor argument:

$factory = new Factory($container, $factoryConfig, false);
