Provides dynamic return type resolution so PHPStan understands that `$container->get(Foo::class)` returns `Foo`. Supported Containers -------------------- [](#supported-containers) - [StellarWP Container Contract](https://github.com/stellarwp/container-contract) (`StellarWP\ContainerContract\ContainerInterface`) - [PSR-11 Container](https://www.php-fig.org/psr/psr-11/) (`Psr\Container\ContainerInterface`) - Any container really as long as you pass its fully qualified class name to the extension as an argument. Requirements ------------ [](#requirements) - PHP 7.4 or higher - PHPStan 2.0 or higher Installation ------------ [](#installation) ``` composer require --dev dpanta94/phpstan-containers ``` If you use [phpstan/extension-installer](https://github.com/phpstan/extension-installer), you're all set! ### Manual Installation [](#manual-installation) If you don't use the extension installer, add the extension to your `phpstan.neon`: ``` includes: - vendor/dpanta94/phpstan-containers/extension.neon ``` Usage ----- [](#usage) Once installed, PHPStan will automatically understand container return types: ``` use Psr\Container\ContainerInterface; class MyService { public function __construct(private ContainerInterface $container) {} public function doSomething(): void { // PHPStan knows $logger is an instance of Logger $logger = $this->container->get(Logger::class); $logger->info('Hello world'); // PHPStan knows $mailer is an instance of MailerInterface $mailer = $this->container->get(MailerInterface::class); $mailer->send($message); } } ``` The extension resolves types when: - The argument to `get()` is a class-string constant (e.g., `Foo::class`) - The class or interface exists in the codebase When using string service IDs (e.g., `$container->get('mailer')`), the extension falls back to the default `mixed` return type. Prefixed containers (Strauss / Mozart) -------------------------------------- [](#prefixed-containers-strauss--mozart) PHPStan keys dynamic return type extensions by the class returned from `getClass()` and only consults them when the value's type has that class in its ancestry. If you ship your dependencies through a namespace prefixer such as [Strauss](https://github.com/BrianHenryIE/strauss) or Mozart, your container interface is rewritten (e.g. `StellarWP\ContainerContract\ContainerInterface` becomes `Acme\Vendor\StellarWP\ContainerContract\ContainerInterface`). The bundled StellarWP and PSR extensions can no longer match it, because the prefixed copy shares no ancestor with the original interface. Register `ConfigurableContainerDynamicReturnTypeExtension` once per prefixed container interface in your `phpstan.neon`: ``` services: - class: DPanta\PHPStan\Containers\ConfigurableContainerDynamicReturnTypeExtension arguments: containerClass: Acme\Vendor\StellarWP\ContainerContract\ContainerInterface tags: - phpstan.broker.dynamicMethodReturnTypeExtension ``` The bundled defaults remain registered, so unprefixed containers keep working with zero configuration.
