我一直在搜索，并没有真正找到太多有用的信息。我希望将 symfony2 路由组件（以及 yaml 组件）与我自己的个人框架一起使用，但尚未找到任何有关基本设置的文档。 symfony site 上的文档很好地解释了如何使用该组件，但在独立设置方面没有太多帮助。
谁能推荐一个可以解释如何设置单个 symfony2 组件的好地方？

标签： symfony routing components yaml
我最终查看了symfony site 上的文档以及 github 上的源代码（Route.php、RouteCollection.php、RouteCompiler.php），并提出了我自己的基本路由器。
就像 symfony 一样，我允许将 4 个参数传递给路由类 -> 1) 模式，2) 默认控制器/动作，3) 模式中每个变量的正则表达式要求，以及 4) 任何选项 -我还没有为此编写代码，因为它不在我的要求中。
我的主/前端控制器 (index.php) 只与静态路由器类对话，该类可以访问 lib\route 命名空间中的其他路由类。
Router::Map 基本上编译一个正则表达式字符串（以及默认控制器/动作和变量名称），该字符串被传递给在 Router::_Process 中用于匹配 httpRequest 的已编译RouteCollection。从那里开始，如果在 process 方法中有匹配项，那么我根据匹配的 compiledRoute 默认控制器/动作的值设置控制器/动作/参数。如果没有 preg_match，那么我使用请求对象中的默认控制器/动作/参数。剩下的就是蛋糕了……
我希望有人觉得这很有用，并且能够节省我今天花在这方面的时间。干杯！
