What is Assetic?

Assetic is an asset management framework for PHP 5.3. Assetic enables you to use a variety of third party tools that will help bring order to your application's Javascripts, stylesheets and images.

How Do I Use Assetic?

There are two distinct approaches you can take when using Assetic:

1. Build, dump and output assets in PHP files that you reference directly from your templates
2. Defining assets in your templates ("on the fly") and use a loader to extract, dump and output them

The first approach is simpler, but the second, with all its moving parts, offers more flexibility and opportunity for optimization.
