FAQ
Example:
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 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.
Informations about the package radiate
Radiate
Introduction
Radiate is a package for managing Events.
Basic Usage
Simply create an instance of the Emitter and emit events!
Creating the Emitter
Radiate requires a pipeline of middleware when being created. The main middleware required to invoke listeners is an
instance of the InvokeListenerMiddleware class.
In order to invoke a Listener, the middleware needs to know the available Listeners ($registry), how to create an
instance of the subscribed Listeners ($locator) and how to determine which method should be invoked ($inflector).
Registrys
A Registry is a simple class responsible of keeping track all of the subscribed Listeners.
Locators
The responsibility of the locator is to take a Fully Qualified Class Name for a Listener and to return an instance. If you are using a Dependency Injection container, then this is where you want to resolve the concrete instance.
Inflectors
The job of the inflector is to determine which method should be called on a particular Listener given a specific Event. Several Inflectors are provided for common setups.
HandleMethodInflector
The HandleMethodInflector ensures the handle() method is returned. A Listener could look like this:
TypehintMethodInflector
The TypehintMethodInflector ensures any method dependent on the type of event is returned. A Listener could look like
this:
When using the TypehintMethodInflector, you can define multiple public methods so that the same Listener can respond
to different events.

Todo
- [ ] Bump to >=PHP7, update codebase (return types, typehint, etc.)
- [ ] Extract examples into example directory
- [ ] Make registry serialisable, and constructable from a serialised registry
