On Sftuts.com today Albert Jessurum has taken a look at Assetic, a tool included in the upcoming Symfony2 framework, as a means for compressing the CSS on a site. It's a simple four-step process and he includes each command you'll need along the way.

Symfony Standard comes bundled with a great library called Assetic for Assets Management in PHP 5.3 (CSS, js, and even image optimization coming soon) developed by Kris Wallsmith. We will be using it to compress our CSS files, thus reducing the time required to download stylesheets in our Symfony2 projects.

The steps are pretty simple (especially if you're at all familiar with Symfony):

• Install the YUI Compressor
• Change the way you call your assets
• Edit your configuration file
• Dump your assets for production

You'll need to have an installation of Symfony2 already set up and running - there's no steps included on that setup.
