Symfony Components : The Event Dispatcher

The Symfony Event Dispatcher animal

After the YAML and the Dependency Injection, it's time for the Symfony Event Dispatcher component to join the crowd of the Symfony components. This component is not new. It has been introduced in symfony 1.1 and is heavily used in the symfony core to make symfony more decoupled and more flexible.

The Symfony Event Dispatcher component is represented by an Octopus.

Of course, you can start using it right away in your non-symfony projects by reading the dedicated book:


Like other published components, the component comes with a test suite that covers 100% of the code, and it is continuously built by the Sensio Labs continuous integration server, Sismo.

Help the Symfony project!

As with any Open-Source project, contributing code or documentation is the most common way to help, but we also have a wide range of sponsoring opportunities.


Great work Fabien! Any chance forms can be spun out into a component next?
Wow, silently the request handler was also added as a coming soon component. I'm really excited now. :-)
@Matthias: You should follow me on Twitter ( as I announce those kind of small things there.
In two weeks, Fabien will tell us that Symfony 2 is out
First off, great job.
Few questions.

Are you planning a symfony components book?
Are you going to let users download compononents documentation as a PDF file?
Nice. That Sismo thing looks sexy. Any chance you open-source it? :)
@Me Again: That's the plan... when it will be ready.
That's great, thanks. Looking forward for it.
Great work. Impressive and excited!

Could Pake be released as a component or separate project? I bet it will be very usefull for developers!
