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.

Informations about the package psr14-event-dispatcher

PSR-14 Event Dispatcher

This library provides an easy-to-use implementation of a PSR-14 event dispatcher, allowing you to manage event-driven functionality in your PHP applications.

Installation

Make sure to include the library in your composer.json or install it directly:

Creating an Event

To create a custom event, extend the Event class provided by the library:

Creating a Listener

A listener class handles the event logic. It should implement an __invoke method that accepts the event as a parameter:

Usage

To use the event dispatcher, register your listeners with a ListenerProvider and dispatch events as needed:

Note: When the PreCreateEvent is dispatched, UserListener will be automatically invoked if the event matches its type.

Example Use Case

Suppose you have a User entity that requires additional logic to be executed after being persisted to the database, such as sending a welcome email or logging activity. You can use the PreCreateEvent and UserListener to encapsulate this behavior, keeping your code clean and following the event-driven design pattern.
