Symfony is a PHP full-stack web framework. It is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP.
优点：
1. 更加注重业务逻辑，减少重复造轮子。
2. 快速开发简装、可持续升级的网站应用。
3. 更深入理解并应用网站开发领域中的最佳实践。

# Hello World
app/console generate:bundle | |
Welcome to the Symfony bundle generator! | |
Are you planning on sharing this bundle across multiple applications? [no]: | |
Your application code must be written in bundles. This command helps | |
you generate them easily. | |
Give your bundle a descriptive name, like BlogBundle. | |
Bundle name: BlogBundle | |
Bundles are usually generated into the src/ directory. Unless you're | |
doing something custom, hit enter to keep this default! | |
Target Directory [src/]: | |
What format do you want to use for your generated configuration? | |
Configuration format (annotation, yml, xml, php) [annotation]: | |
Bundle generation | |
> Generating a sample bundle skeleton into app/../src/BlogBundle | |
created ./app/../src/BlogBundle/ | |
created ./app/../src/BlogBundle/BlogBundle.php | |
created ./app/../src/BlogBundle/Controller/ | |
created ./app/../src/BlogBundle/Controller/DefaultController.php | |
created ./app/../tests/BlogBundle/Controller/ | |
created ./app/../tests/BlogBundle/Controller/DefaultControllerTest.php | |
created ./app/../src/BlogBundle/Resources/views/Default/ | |
created ./app/../src/BlogBundle/Resources/views/Default/index.html.twig | |
created ./app/../src/BlogBundle/Resources/config/ | |
created ./app/../src/BlogBundle/Resources/config/services.yml | |
> Checking that the bundle is autoloaded | |
> Enabling the bundle inside app/AppKernel.php | |
updated ./app/AppKernel.php | |
> Importing the bundle's routes from the app/config/routing.yml file | |
updated ./app/config/routing.yml | |
> Importing the bundle's services.yml from the app/config/config.yml file | |
updated ./app/config/config.yml | |
Everything is OK! Now get to work :). |
路由建议：
常访问的路由放前面，不常访问的路由放后面，可以提高效率
路由定义的两种常用写法：
1.Annotation，允许在方法的上面以注释形式定义方法运行状态，适用于方法定义清晰统一时
/** | |
* @Route("hi/{name}") | |
*/ |
2.routing.yml，symfony2 常用的配置格式
#app/config/routing.yml 中注册 | |
blog: | |
resource: "@BlogBundle/Resources/config/routing.yml" | |
prefix: / | |
#src/BlogBundle/Resources/config/routing.yml 中添加具体路由 | |
blog: | |
pattern: /hi/{name} | |
defaults: { _controller: BlogBundle:Default:index } |
路由匹配查找
app/console router:match /hi/{name} |
# Controller
Request
Response
Session
# Twig
基本语法
核心概念：用类的继承概念关系去管理页面之间的关系
继承 复写
