Presentation by Mattia A. Fritz

What is Symfony and what it is not!

What it is

It's a platform to develop stable, secure, decoupling and reusable applications.
It's a toolbox that helps you reduce development time.
It's a set of established practices and code standards.
It's a common environnement to integrate custom and third party code.
It's a community that shares the same development tools and best practises.

What it's not!

It's not a ContentManagement System, you can't do anything out of the box.
It's not a ready to use site template, you must develop your application from scratch, with your code or third party code.
It's not a software that helps you write code, you still need your favourite IDE (some of which have Symfony syntax integrated).

So why
should I use
Symfony?

Reason #1

It's fun!

Bla bla bla bla bla bla bla bla bla bla...

Reason #2

It's cool!

Bla bla bla bla bla bla bla bla bla bla...

Reason #3

I use it!

Bla bla bla bla bla bla bla bla bla bla...

Not convinced?

Ok...
seriously!

Reason #1

It's a PHP framework

PHP is the free server-side scripting language most used in the web right now. More than 200 mio. websites use it!

Reason #2

It's a philosophy

Symfony is developed with developers' needs in mind. It's developed for you to understand, not simply to follow!

Reason #3

It's a community

The open source licence allows developers to freely adopt Symfony and share both their code and experience!

This is actually serious stuff inspired and adapted from the Symfony official website.

More
about Symfony?

Some useful links:

Symfony: The official Symfony Website is the best place to start digging into the framework.
Documentation: The official documentation on the Symfony Website covers all the principal aspects to set up a Symfony application.
Knp Bundles: Bundles are a collection of files that form a particular feature (eg, a Blog). Knp Bundles is a repository for many ready-to-implement bundles that you can add to your application.
Source on Git: Symfony's code is open-source and thus anybody can see it. The most practical way to see it, without downloading, is on Git.
