# Yaf_Application::bootstrap

(Yaf >=1.0.0)

Yaf_Application::bootstrap — 调用 bootstrap

### 说明

public Yaf_Application::bootstrap(Yaf_Bootstrap_Abstract `$bootstrap` = ?): void

运行 Bootstrap，所有在 Bootstrap 中定义并以“_init”前缀命名的方法都将按照声明的顺序调用，如果没有提供参数 bootstrap，Yaf 将在 application.directory 下寻找 Bootstrap。

### 参数

`bootstrap`

  Yaf_Bootstrap_Abstract 实例

### 返回值

Yaf_Application 实例

### 示例

示例 #1 Bootstrap 示例

`<?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";
}
}
?>`

示例 #2 Yaf_Application::bootstrap() 示例

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

以上示例的输出类似于：

    1st called
    2nd called
