Yaf_Application::__construct — Yaf_Application constructor

### Description

public Yaf_Application::__construct(mixed `$config`, string `$envrion` = ?)

Instance a Yaf_Application.

### Parameters

`config`

  A ini config file path, or a config array

  If is a ini config file, there should be a section named as the one defined by yaf.environ, which is "product" by default.

  Example #1 A ini config file example

      [product]
      ;this one should alway be defined, and have no default value
      application.directory=APPLICATION_PATH

      ;following configs have default value, you may no need to define them
      application.library = APPLICATION_PATH . "/library"
      application.dispatcher.throwException=1
      application.dispatcher.catchException=1

      application.baseUri=""

      ;the php script ext name
      ap.ext=php

      ;the view template ext name
      ap.view.ext=phtml

      ap.dispatcher.defaultModule=Index
      ap.dispatcher.defaultController=Index
      ap.dispatcher.defaultAction=index

      ;defined modules
      ap.modules=Index
