README

这是一个轻量级的依赖注入容器，与任何框架解耦。这个库可以用于生产，但我建议使用来自更大社区（如Symfony、Laravel或Laminas）的依赖注入容器会更好。

这个库是为了娱乐而开发的，但如果有人使用它，则会得到支持。

此项目也可以作为一个示例，以简化的方式展示现代DI容器的工作原理。

工作原理

    composer require marcel-strahl/container

适用于PHP >= 8.0

此库使用PSR容器。

用法

<?php

use MarcelStrahl\Container\FileLoader\AdapterBuilder;
use MarcelStrahl\Container\FileLoader\PHPArrayAdapter;
use MarcelStrahl\Container\ObjectBuilder\ObjectBuilderFactory;
use MarcelStrahl\Container\Delegator\ObjectDelegator;
use MarcelStrahl\Container\ClassContainer;
use MarcelStrahl\Container\ObjectContainer;
use MarcelStrahl\Container\AppContainer;
use MarcelStrahl\Container\Dto\ObjectStore;
use MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummy;

$adapter = (new AdapterBuilder())->build(PHPArrayAdapter::class);

$path = sprintf('%s/../Unit/FileLoader/php_array_config.php', __DIR__);
Assert::stringNotEmpty($path);

$builderFactory = new ObjectBuilderFactory();
$delegator = new ObjectDelegator($builderFactory);

$classStore = $adapter->loadFileFromPath($path, ClassStore::create());

$classContainer = ClassContainer::create($classStore);
$classContainer->compile();

$objectContainer = new ObjectContainer(ObjectStore::create(), $delegator);

$app = AppContainer::initialize($classContainer, $objectContainer);
$builderFactory->setContainer($app);

// Insert `$app` into your application context

您需要遵循配置结构。需要注意的是，如果您不想指定别名或工厂，也可以指定一个空数组。

<?php

declare(strict_types=1);

return [
    // class => [factory?: class-string, alias?: class-string, id?: non-empty-string]
    \MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummy::class => [],
    \MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummyWithFactory::class => [
        'factory' => \MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummyWithFactory\Factory::class,
    ],
    \MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummyWithServiceId::class => [
        'id' => 'serviceId',
    ],
    \MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummyWithAlias::class => [
        'alias' => \MarcelStrahl\Tests\Unit\FileLoader\data\AliasInterface::class,
    ],
    \MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummyWithFactory::class => [
        'alias' => \MarcelStrahl\Tests\Unit\FileLoader\data\AliasInterface::class,
        'id' => 'serviceId',
        'factory' => \MarcelStrahl\Tests\Unit\FileLoader\data\PhpArrayLoaderClassDummyWithFactory\Factory::class,
    ],
];
