$ this- & gt; preinit () // 당분간 사용하지 않으며 추후 확장에 맡길 것으로 추정됩니다 $this->initSystemHandlers();//오류 처리 설정 $this->registerCoreComponents();//핵심 컴포넌트 등록 $this->configure($config); //구성 파일을 통해 클래스의 속성을 확장하고 비어 있으면 아무것도 하지 않습니다 $this->attachBehaviors($this->behaviors); $this->preloadComponents(); $this->init(); } $this 아래의 일부 메소드는 상위 클래스에서 올 수 있으므로 현재 클래스에서 찾을 수 없습니다. 그렇지 않은 경우 ctrl+f를 사용하여 검색하는 것입니다. 확인해보세요 : 추상 클래스 CApplication은 CModule을 확장합니다. 분명히 CModule에 들어가야 합니다. 여전히 원하는 방법을 찾을 수 없으면 이전 프로세스를 계속하세요. 추상 클래스 CModule은 CComponent를 확장합니다 CComponent 클래스까지 이곳이 현재 이들의 본거지라는 뜻이다. 코드의 주석에서도 확인할 수 있습니다. CComponent는 모든 구성요소의 기본 클래스입니다 제 생각이 맞다는 뜻입니다. 네, 기본 클래스입니다. 코드를 통해 현재 애플리케이션에서 많은 매개변수가 비어 있기 때문에 많은 로직을 직접 건너뛰었음을 알 수 있습니다. 이것을 보면 $this의 내용은 대략적으로 알 수 있습니다. 다시 돌아보자 새 CWebApplication($config)->run() 반환; 이전의 레이어별 분석을 통해 이때의 실행 방식도 쉽게 찾아볼 수 있다. CApplication 바로 내부:
