Where should I add my internal classes file in symfony2?

Question

我正在将一个旧项目移植到symfony2以便开始学习该框架，但我无法实现如何正确添加我在PHP文件中拥有的一些辅助函数的方法。

Answer 1

Services . Wrap those function in a class (like Helper ), define the class as a service and then inject it where needed (controller or another service, or even into a cli command).

The namespace (thus the path, as you tagged the question with psr-0) is up to you.
