## 运行时配置

这些函数的行为受 php.ini 中的设置影响。

Yaf 配置选项
名字 | 默认 | 可修改范围 | 更新日志
--- | --- | --- | ---
yaf.library |  | `INI_ALL` |
yaf.action_prefer | 0 | `INI_ALL` |
yaf.lowcase_path | 0 | `INI_ALL` |

yaf.environ | product | `INI_SYSTEM` |
yaf.use_namespace | 0 | `INI_SYSTEM` |

这是配置指令的简短说明。

`yaf.library` string

  全局库路径，Yaf_loader 会在此目录下搜索全局库。

`yaf.action_prefer` int

  If there is only one part in PATH_INFO, should it consider as a controller or action.

  如果此配置为 On，将视为 Action 名。

`yaf.lowcase_path` int

  Whether lowercase all the path during the class autoloading.

`yaf.use_spl_autoload` int

  When this value is On, if Yaf_Loader can not find a class, it will return `false`, then give chance to other auto load function to be called.

  When this value is Off, if Yaf_Loader can not find a class, it will return `true`, and make the class autoloading failed immediately.

  > 注意:

  > Yaf will register its loader during a instantiation of Yaf_Application, so any other auto loaders which is register before the instantiation will be called before Yaf_Loader::autoload().

  When this value is Off(default), Yaf_Loader::autoload() will always return `true`.

`yaf.forward_limit` int

  The max forward count, default is 5. that means you can have a max value of 5 in the forward stack.

  This is a protection for prevent recursive Yaf_Controller_Abstract::forward().

`yaf.name_suffix` int

  When this On, Yaf_Loader will identify a class by it's suffix to decide whether it is a MVC Class.

  When this Off, Yaf_Loader will look at the prefix of the class name.

`yaf.name_separator` string

  When this is not empty, Yaf_Loader will identify the class suffix and string value of this.

  For example, when this value is "_", Yaf_Loader will take Index_Controller as a Controller Class, IndexController as a normal class.

`yaf.cache_config` int

  If this is On, and in the meantime you are using ini config file as the parameter of Yaf_Application(), the compiling result of the ini config file will be cached in the PHP process.

  > 注意:

  > Yaf examine the mtime of the ini file, if it was changed since last compiling, Yaf will reload it.

  警告

  Yaf use the ini file path as the cache entry key, so do use the absolute path in ini file path, otherwise there might be some conflicts if two application use the same relative path of ini config.

`yaf.environ` string

  默认值是“product”，用于 Yaf 获取 ini 配置文件中的配置部分。

  That is, if this value is "product", Yaf will use the section named "product" in the ini config file(the first parameter of the Yaf_Application) as the final config of the Yaf_Application.

`yaf.use_namespace` int

  如果值为 On，Yaf 的所有类都将以命名空间样式命名。

  例如：

      Yaf_Route_Rewrite => \Yaf\Route\Rewrite
      Yaf_Request_Http  => \Yaf\Request\Http

  有个例外，就是像 Yaf_Controller_Abstract 这样的类。最后部分是 PHP 的关键字，不能用作类名，对于这样的类，只能：

      Yaf_Controller_Abstract => \Yaf\Controller_Abstract
      Yaf_Route_Static => \Yaf\Route_Static
