Runtime Configuration

The behaviour of these functions is affected by
settings in php.ini.

Here’s a short explanation of the configuration
directives.

yaf.library
string

The global library path, Yaf_loader will search
global library in this directory.

yaf.action_prefer integer

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

If this configure On, it will be considered as a
Action name.

yaf.lowcase_path integer

Whether lowercase all the path during the class
autoloading.

yaf.use_spl_autoload integer

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.

Note:

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 integer

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 integer

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 integer

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.

Note:

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

Warning

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

This value is “product” by default, used for Yaf to
fetch the config section of a ini config file.

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 integer

Only works as of PHP 5.3, if this value is On, All
classes of Yaf will named in namespace style.

For example:

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

There is a exception, that is some classes like Yaf_Controller_Abstract. The last component is a
keyword of PHP, could not be used as a class name, so for such
classes:

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