Yaf_Application::bootstrap()

(Yaf >=1.0.0)

调用bootstrap

说明

publicYaf_Application::bootstrap([Yaf_Bootstrap_Abstract$bootstrap]): void

指示Yaf_Application去寻找Bootstrap，并按照声明的顺序，执行所有在Bootstrap类中定义的以_init开头的方法。如果没有提供变量bootstrap，Yaf默认会去application.directory中寻找Bootstrap。

参数

$bootstrap: A Yaf_Bootstrap_Abstract instance

返回值

Yaf_Application instance

范例

Example #1 A Bootstrap()example

<?php
/**
 * This file should be under the APPLICATION_PATH . "/application/"(which was defined in the config passed to Yaf_Application).
 * and named Bootstrap.php,  so the Yaf_Application can find it 
 */
class Bootstrap extends Yaf_Bootstrap_Abstract {
    function _initConfig(Yaf_Dispatcher $dispatcher) {
        echo "1st called\n";
    }
    function _initPlugin($dispatcher) {
        echo "2nd called\n";
    }
}
?>

Example #2 Yaf_Application::bootstrap()example

<?php
defined('APPLICATION_PATH')                  // APPLICATION_PATH will be used in the ini config file
    || define('APPLICATION_PATH', __DIR__)); //__DIR__ was introduced after PHP 5.3
$application = new Yaf_Application(APPLICATION_PATH.'/conf/application.ini');
$application->bootstrap();
?>

以上例程的输出类似于：

1st called
2nd called

Yaf_Bootstrap_Abstract

Here is an example of a Bootstrap loading a session class then loading a database class and using a db configuration from the application config.
<?php
class Bootstrap extends Yaf_Bootstrap_Abstract
{
  public function _initSession(Yaf_Dispatcher $dispatcher)
  {
    $session = new Vendor\Session();
    $session->start();
  }
  public function _initDatabase(Yaf_Dispatcher $dispatcher)
  {
    $config = Yaf_Application::app() >getConfig() >application->database;
    Yaf_Registry::set('db', Vendor\Database($config));
  }
}
?>
