environment

：依照不同的需求，可藉由建立不同的 configuration file 設定不同的環境，不須重寫程式碼，切換不同的 configuration file 即可影響程式的運行，不須改寫程式碼

Bundle

 logical names：
作用：類似 URL ，用以存取指定的資源，而非該資源的實體地址
原文：" they abstract where the resource is actually stored "

Logical Controller Names

format BUNDLE_NAME:CONTROLLER_NAME:ACTION_NAME
For instance,
AcmeDemoBundle:Welcome:index
maps to
the indexAction method from the Acme\DemoBundle\Controller\WelcomeController class



create a bundle - AcmeNewBundle - and specify that it overrides AcmeDemoBundle. When Symfony loads the AcmeDemoBundle:Welcome:index controller, it will first look for the WelcomeController class in AcmeNewBundle and, if it doesn't exist, then look inside AcmeDemoBundle. This means that one bundle can override almost any part of another bundle
