The myths: symfony is... • ... hard to learn • ... extremely coupled • ... not really programming, just conﬁguration • ... restrictive • ... badly performing • ... the ultimate tool

What I want to prove... • symfony is not crap • symfony ﬁts in of pookey’s 10%

Pookey’s 10%

Pookey’s 10% <pookey> PHP is a fucking ﬁlthy horrible language in 90% of usecases.

cc-by 2.0 http://www.ﬂickr.com/photos/shonk/418180402/ Symfony is hard to learn

Steep Learning Curve • Full-stack • MVC • ORM • YAML

Great documentation • The Deﬁnitive Guide to symfony • Practical Symfony • Propel Edition • Doctrine Edition • Various other languages

Great documentation • Ofﬁcial books in digital form • Forms in Action • symfony and Doctrine • The Cookbook • API documentation • Tutorials & Screencasts

Community • IRC: #symfony on freenode • Forum • Mailinglists • Wiki • Snippets • Blog posts • Various local sites

Symfony is hard to learn • Steep learning curve • Great documentation (online and ofﬂine) • Friendly and supportive community

Symfony is hard to learn The Verdict

cc-by 2.0 http://www.ﬂickr.com/photos/u-suke/138067687/ Symfony is extremely coupled

Perhaps in 1.0 • symfony was the glue between components • ORM integrated in the core • It was full-stack or nothing

Symfony is extremely coupled by-nc-nd 3.0 http://www.symfony-project.org/blog/2009/02/18/dailymotion-powered-by-symfony

Symfony is extremely coupled • 1.0 had quite some coupling • 1.1 introduced decoupling of the core: symfony platform • it is now possible to use core symfony classes without symfony

Symfony is extremely coupled The Verdict

symfony is not really programming, just conﬁguration

Just conﬁguration is no fun

Programming should be fun • No boring repetitive tasks • No standard stuff you did 100 times before • Write cool stuff • Focus on the cool parts

Yes, there is conﬁguration • To minimize the boring tasks • To ensure you don’t repeat yourself • To enable you to concentrate on complex logic

So what is conﬁgured? • database credentials • caching • access control (authorization and authentication) • application speciﬁc values • routing • admin generator

So where do I touch code? • Your custom complex business logic • Application speciﬁc controller code • View displays • Custom administration tasks • Your own libraries

symfony is not really programming, just conﬁguration The Verdict

by-nc-sa 2.0 http://www.ﬂickr.com/photos/two-wrongs/205467442/ symfony is restrictive

symfony is restrictive • Default directory structure • Default set of classes • Default set of libraries • ORM included

Default directory structure • Easily change the most important directory locations: • document root • cache directory • log directory • You usually don’t need to do this!

Default set of classes • Default set offers most common uses • Easy to use your own custom class using conﬁguration

Default set of libraries • Default libraries • lime (unit testing) • prototype • scriptaculous • Dozens of plugins • jquery, dojo, extjs, YUI • PHPUnit

ORM included • Propel is default • Doctrine is distributed with symfony • There is no need for an ORM

You can just disable both!

Hell, disable the database • When you don’t use the database • Models approach web services

symfony is restrictive The Verdict

Symfony is badly performing

Symfony doesn’t perform

Disclaimer: No benchmarks!

by-sa 2.0 http://www.ﬂickr.com/photos/mattieb/131215442/

Symfony doesn’t perform • Slow • Hard on the server

Symfony doesn’t perform • Overhead • just like any framework • tweak it the right way

Symfony doesn’t perform • Select your caching strategy • Page caching • Function caching • Query caching • Supercache!

Cache

Symfony doesn’t perform • Turn off what you don’t need • ORM • Plugins • Database • Logging • Helpers

Symfony doesn’t perform • Don’t believe me! • Yahoo! Answers • Delicious.com • DailyMotion.com

Symfony is badly performing The Verdict

by-nc-nd 2.0 http://www.ﬂickr.com/photos/mandolux/34418046/ symfony is the ultimate tool

Symfony is the ultimate tool • full-stack framework • based on MVC • automation of common tasks • supports agile approach • MIT license • DRY

Symfony is the ultimate tool • full-stack framework • based on MVC • automation of common tasks • supports agile approach • MIT license • DRY • All the buzzwords

Symfony is the ultimate tool • Learning curve is more steep • Has to ﬁt your project • Has to ﬁt your project team • There is no single ultimate tool

symfony is the ultimate tool The Verdict
