This article mainly shares with you how the CI framework obtains the controller name and method name. There are three methods in total. I hope it can help you.
The first method:
Even if there are __CLASS__, __FUNCTION__ magic variables, but in the parent class controller, or In the model, only the class name and method name of the current class can be obtained.
Second method:
##$this- >uri->segment(3, 0 );
This is obtained through the URL. In case the url route is customized, this method is not very elegant.
##The third method: (Perfect) $con = $this->router->fetch_class();//获取控制器名
$func = $this->router->fetch_method();//获取方法名
