FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

The package is a PSR-15 middleware dispatcher. Given a set of middleware and a request instance, dispatcher executes it and produces a response instance.

Requirements

Installation

The package could be installed with Composer:

General usage

To use a dispatcher, you need to create it first:

In the above $diContainer is an instance of PSR-11 \Psr\Container\ContainerInterface and $eventDispatcher is an instance of PSR-14 Psr\EventDispatcher\EventDispatcherInterface.

After dispatcher instance obtained, it should be fed with some middleware:

In the above we have used a callback. Overall the following options are available:

For handler action and callable typed parameters are automatically injected using dependency injection container. Current request and handler could be obtained by type-hinting for ServerRequestInterface and RequestHandlerInterface.

After middleware set is defined, you can do the dispatching:

Given a request dispatcher executes middleware in the set and produces response. First specified middleware will be executed first. For each middleware \Yiisoft\Middleware\Dispatcher\Event\BeforeMiddleware and \Yiisoft\Middleware\Dispatcher\Event\AfterMiddleware events are triggered.

Creating your own implementation of parameters resolver

Parameters resolver could be customized by providing your own ParametersResolverInterface implementation:

Then it could be used like the following:

To combine several parameters' resolvers use CompositeParametersResolver:
