The symfony project keeps getting bigger and bigger all of the time, and they've just expanded even further with the release of a new symfony-based application for their own site - a code snipped library, a.k.a "Snipeet".
Is there a better way to learn a new language - or a framework - than by looking at showcase apps? Just like us, you probably don't want to spend hours reading the manual. You prefer to find a code snippet that does something close to what you need, copy it, have it run, and then customize it for your own requirements. You try to understand only what must be adapted, to keep your mind clear and focused on your primary task.
Taking this mentality out to the next step, the team created the code snippets section to help find those little bits you need to bridge the gap in your code. And, of course, not only can you use the tool to view and contribute snippets to the symfony project, but you can also grab the code for the self-contained version of the project as well.
