- 21. cc-by 2.0 http://www.flickr.com/photos/u-suke/138067687/ Symfony is extremely coupled
- 22. Perhaps in 1.0 • symfony was the glue between components • ORM integrated in the core • It was full-stack or nothing

- 29. symfony is not really programming, just configuration
- 30. Just configuration is no fun
- 31. Programming should be fun • No boring repetitive tasks • No standard stuff you did 100 times before • Write cool stuff • Focus on the cool parts
- 32. Yes, there is configuration • To minimize the boring tasks • To ensure you don’t repeat yourself • To enable you to concentrate on complex logic
- 33. So what is configured? • database credentials • caching • access control (authorization and authentication) • application specific values • routing • admin generator
- 34. So where do I touch code? • Your custom complex business logic • Application specific controller code • View displays • Custom administration tasks • Your own libraries

- 37. by-nc-sa 2.0 http://www.flickr.com/photos/two-wrongs/205467442/ symfony is restrictive
- 38. symfony is restrictive • Default directory structure • Default set of classes • Default set of libraries • ORM included
- 39. Default directory structure • Easily change the most important directory locations: • document root • cache directory • log directory • You usually don’t need to do this!

- 41. Default set of libraries • Default libraries • lime (unit testing) • prototype • scriptaculous • Dozens of plugins • jquery, dojo, extjs, YUI • PHPUnit
- 42. ORM included • Propel is default • Doctrine is distributed with symfony • There is no need for an ORM
- 43. You can just disable both!
- 44. Hell, disable the database • When you don’t use the database • Models approach web services
