[디자인패턴] php 로 알아보는 Builder pattern (주식 정보 가져오기, 주식 정보 API만들기- kospi, kosdaq, krx)

디자인 패턴중 Builder pattern 을 알아보도록 합시다.

Builder pattern 이 무엇이지는 여기 를 참고하시면

많은 도움이 되실겁니다. 

 

아래 소스는 제가 사용하는 실제 주식정보(kospi, kosdaq, krx) 가져오는 API 일부 소스입니다.

현재는 종합주가지수 (kospi, kosdaq, krx) 정보만 가져오지만

개별 주식 종목 크롤링 하는것도 가능합니다.

기회가 되면 개별 주식 종목 API 알려드리겠습니다.
