우리에 대한 정보를 보여주는 PHP 개발 기업 웹사이트 튜토리얼

사용자 조작 방법(추가, 삭제, 수정, 확인)을 배운 후에는 다음 기능을 개발하는 것이 매우 간단할 것입니다. SQL 문이 다르다는 점만 제외하면 대부분 동일하지만 기본적으로 원칙은 같습니다. 유사

다음을 살펴보겠습니다. 일부 정보 표시에 관해

표시된 내용이 너무 길면 문자열 길이를 가로채야 합니다

이것을 사용하는 방법을 캡슐화했습니다. 0부터 시작하는 아래 출력 콘텐츠 부분의 코드를 살펴보세요. Take 20

삭제 및 수정에도 ID가 있습니다

지속적인 학습
