mysql 삽입 및 업데이트 방법을 이해하는 데 도움이 필요합니다. 나는 Mamp를 실행 중이며 php와 mysql이 작동 중임을 알고있다. 내 데이터베이스 설정 방법은 정보 테이블에 키가 있다는 것입니다. 데이터는 데이터베이스로 암호화되고 passbook.html에 표시되면 암호 해독됩니다. 현재 데이터를 업데이트 할 수 있지만 사용자 이름이나 암호가 변경되면 새 항목이 업데이트되는 대신 데이터베이스에 저장됩니다. 데이터를 업데이트하려면이 문제를 어떻게 해결할 수 있습니까? 암호 또는 사용자 이름이 변경되면 업데이트가 수행되어야합니다. 웹 사이트가 변경되면 새 항목이 만들어지고 이전 항목이 제거되어야합니다.mysql 삽입 및 업데이트

감사합니다. 암호화 계획으로 무엇을 권하고 싶습니까? – CrazyJohnny
