Tribe Libs 容器使用 PHP-DI 来帮助你构建 对象图，允许自动装配依赖注入。

可变容器

通常，你应该设计你的服务为 无状态。

然而，对于长时间运行的过程（如队列）或在必须从头创建一个全新对象及其所有依赖项的情况下，可以使用可变容器。

这开启了 makeFresh() 方法，它的工作方式与 PHP-DI 的 make() 方法 完全相同，但会清除容器中解析的条目，这意味着对象的所有依赖项也将从头开始重新创建。

注意：仅在必要时使用此功能，这不如默认容器性能好。

在定义器中

<?php declare(strict_types=1);

namespace Tribe\Project\Feature;

use Psr\Container\ContainerInterface;
use Symfony\Contracts\HttpClient\HttpClientInterface;
use Tribe\Explore_Navigation\Azure\Factories\Client_Factory;
use Tribe\Libs\Container\Definer_Interface;
use Tribe\Libs\Container\MutableContainer;
use Tribe\Libs\Container\Container;

class My_Feature_Definer implements Definer_Interface {

	public function define(): array {
		return [
		    // Define our abstract to the interface, placing our existing container inside the mutable container.
		    MutableContainer::class => static fn ( ContainerInterface $c ) => ( new Container() )->wrap( $c ), 
		];
	}

}

然后你可以使用 makeFresh() 方法在每次调用时创建全新的对象

<?php declare(strict_types=1);

namespace Tribe\Project\Feature;

use Tribe\Libs\Container\Abstract_Subscriber;
use Tribe\Libs\Container\MutableContainer;

class My_Queue_Factory {

    protected MutableContainer $container;
    
    public function __construct( MutableContainer $container ) {
        $this->container = $container;
    }
    
    /**
     * Make a fresh object.
     * 
     * @param string $class_name e.g. \Tribe\Project\Feature\SomeFeature::class
     * 
     * @return mixed|string
     */
    public function make( string $class_name ) {
        return $this->container->makeFresh( $class_name );
    }

}

然后调用你的工厂

<?php declare(strict_types=1);

namespace Tribe\Project\Feature;

use Tribe\Libs\Container\Abstract_Subscriber;
use Tribe\Libs\Container\MutableContainer;

class My_Feature_Subscriber extends Abstract_Subscriber {

	public function register(): void {
		add_action( 'init', function(): void {
		    // Both of these will be completely separate instances,
		    // including any dependencies SomeFeature::class has.
		    var_dump( $this->container->get( MutableContainer::class )->make( '\Tribe\Project\Feature\SomeFeature::class' ) );
		    
		    var_dump( $this->container->get( MutableContainer::class )->make( '\Tribe\Project\Feature\SomeFeature::class' ) );
		    
		    // This will be the same instance as the last freshly made object
		    var_dump( $this->container->get( SomeFeature::class ) );		    
		}, 10, 0 );
	}

}
