YII学习第十四天，YII的执行过程
二、controllers里的$this和models里的$this含义是不一样的。?
在controllers里，可以$this->current_user，因为current_user已经在Controller.php里定义。?
而在models里，$this是AR类。?
一、分析一个具体的yii执行过程?
#11 ../protected/controllers/OutsourceController.php(206): OutsourceController->doAction('suspend')?
#12 ../Yii-1.1/framework/web/actions/CInlineAction.php(32): OutsourceController->actionSuspend()?
#13 ../Yii-1.1/framework/web/CController.php(300): CInlineAction->run()?
#14 ../Yii-1.1/framework/web/filters/CFilterChain.php(129): CController->runAction(Object(CInlineAction))? //运行Action?
#15 ../protected/components/Controller.php(83): CFilterChain->run()?
#16 ../Yii-1.1/framework/web/filters/CInlineFilter.php(59): Controller->filterAccessAuth(Object(CFilterChain))//自定义Controller?
#17 ../Yii-1.1/framework/web/filters/CFilterChain.php(126): CInlineFilter->filter(Object(CFilterChain))?
#18 ../Yii-1.1/framework/web/CController.php(283): CFilterChain->run()?
#19 ../Yii-1.1/framework/web/CController.php(257): CController->runActionWithFilters(Object(CInlineAction), Array)?
/*-------------------------------------?
在CController.php的run('suspend')方法中，执行了?
if($parent->beforeControllerAction($this,$action))?
{?
$this->runActionWithFilters($action,$this->filters());//带过滤的运行action。也即运行controller的时候还没加入过滤。?
$parent->afterControllerAction($this,$action);?
}?
在runActionWithFilters方法中又执行了CFilterChain::create($this,$action,$filters)->run();?
该方法先create，再run，在run方法中又执行了$filter->filter($this); 在filter方法中?
$method='filter'.$this->name;?
$filterChain->controller->$method($filterChain);?
----------------------------------------*/?
#20 ../Yii-1.1/framework/web/CWebApplication.php(320): CController->run('suspend')????????????????????
#21 ../Yii-1.1/framework/web/CWebApplication.php(120): CWebApplication->runController('outsource/suspend') //运行Controller?
#22 ../Yii-1.1/framework/base/CApplication.php(135): CWebApplication->processRequest()?
#23 /url/index.php(28): CApplication->run()
