The document discusses common myths about the Symfony framework. It addresses criticisms that Symfony is hard to learn, extremely coupled, focuses only on configuration rather than programming, is restrictive, performs poorly, and claims it is the ultimate tool. For each myth, the document provides counter arguments explaining why Symfony is easy to learn with documentation and community support, has become less coupled over time, involves significant programming beyond just configuration, and allows for flexibility and customization. It also notes performance depends on caching and configuration choices.

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

- 43. symfony is restrictive • Default directory structure • Default set of classes • Default set of libraries • ORM included
- 44. Default directory structure • Easily change the most important directory locations: • document root • cache directory • log directory • You usually don’t need to do this!
- 45. Default set of classes • Default set offers most common uses • Easy to use your own custom class using configuration
- 46. Default set of libraries • Default libraries • lime (unit testing) • prototype • scriptaculous • Dozens of plugins • jquery, dojo, extjs, YUI • PHPUnit
- 47. ORM included • Propel is default • Doctrine is distributed with symfony • There is no need for an ORM
- 48. You can just disable both!
