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()
