Starting with Symfony2
0 likes1,947 views
The document discusses Symfony2, an open-source PHP web application framework. It describes Symfony2 as a set of decoupled components that form a full-stack framework. It also discusses key Symfony2 concepts like bundles, the service container, and the anatomy of a request from the reverse proxy to controller response. The document promotes Symfony2's support for caching dynamic content through edge side includes and client side includes.

- 12. What Symfony2 is not MVC Framework @zenstruck
- 13. HTTP Framework Request Response @zenstruck
- 14. HTTP Framework Request Response I don't like MVC because that's not how the web works. Symfony2 is an HTTP framework; it is a Request/Response framework. That's the big deal. The fundamental principles of Symfony2 are centered around the HTTP specification. - Fabien Potencier @zenstruck
- 15. Bundles ● Everything is a bundle (even the framework is a collection of core bundles) ● Bundles contain: ● Configuration/Translations/Documentation ● Routes/Controllers/Views ● Public resources (js/css/images) ● Services/Events/Models/Forms etc (* don't make your bundle a library) ● Tests ● NOT VENDOR LIBS ● Override with child bundle ● 690+ bundles on knpbundles.com @zenstruck

- 27. “Killer” Feature Symfony2 Reverse Proxy @zenstruck
- 28. 3 Types of HTTP Cache ● From the docs: ● Browser caches: Every browser comes with its own local cache that is mainly useful for when you hit "back" or for images and other assets. The browser cache is a private cache as cached resources aren't shared with anyone else. ● Proxy caches: A proxy is a shared cache as many people can be behind a single one. It's usually installed by large corporations and ISPs to reduce latency and network traffic. ● Gateway caches: Like a proxy, it's also a shared cache but on the server side. Installed by network administrators, it makes websites more scalable, reliable and performant. @zenstruck
