This Yii framework package provides the application class, as well as the events and handlers needed to interact with HTTP. The package is implemented using PSR-7 interfaces.

Requirements

• PHP 8.1 - 8.5.

Installation

The package could be installed with Composer:

composer require yiisoft/yii-http

General usage

In case you use one of the Yii 3 standard application templates, then the application is already configured there and is running using yiisoft/yii-runner-http package.

If not, then use one of the HTTP runners that is suitable for your environment:

• HTTP
• RoadRunner

and create an entry script as described in readme of the packages.

If you do not use Yii HTTP runners, then the code for launching the application in your entry script may look like this:

use Yiisoft\Yii\Http\Application;
use Yiisoft\Yii\Http\Handler\NotFoundHandler;
use Yiisoft\Yii\Http\Handler\ThrowableHandler;

/**
 * @var Psr\EventDispatcher\EventDispatcherInterface $eventDispatcher
 * @var Psr\Http\Message\ResponseFactoryInterface $responseFactory
 * @var Psr\Http\Message\ServerRequestInterface $request
 * @var Yiisoft\ErrorHandler\Middleware\ErrorCatcher $errorCatcher
 * @var Yiisoft\Middleware\Dispatcher\MiddlewareDispatcher $dispatcher
 */

$fallbackHandler = new NotFoundHandler($responseFactory);
$application = new Application($dispatcher, $eventDispatcher, $fallbackHandler);

try {
 $application->start();
 $response = $application->handle($request);
 // Emit a response.
} catch (Throwable $throwable) {
 $handler = new ThrowableHandler($throwable);
 $response = $errorCatcher->process($request, $handler);
 // Emit a response with information about the error.
} finally {
 $application->afterEmit($response ?? null);
 $application->shutdown();
}
