PHP 이메일 보내기

이 글에서는 PHP에서 첨부 파일을 지원하는 이메일을 보내기 위해 smtp를 사용하는 예를 주로 소개합니다. 이 코드는 많은 실제 응용 프로그램에서 사용되었습니다.

경량 PHP 이메일 전송에는 smtp 서버 및 코드 많은 실제 사용을 거쳐 이제 모든 사람과 코드를 공유합니다

mPDF는 UTF-8로 인코딩된 HTML에서 PDF 파일을 생성할 수 있는 PHP 라이브러리입니다. 원저자인 Ian Back은 자신의 웹 사이트에서 "즉시" PDF 파일을 출력하고 다양한 언어를 처리하기 위해 mPDF를 작성했습니다. HTML2FPDF와 같은 원본 스크립트보다 유니코드 글꼴을 사용할 때 속도가 느리고 더 큰 파일을 생성하지만 CSS 스타일 등을 지원하고 많은 개선 사항이 있습니다. RTL(아랍어, 히브리어), CJK(중국어, 일본어, 한국어)를 포함한 거의 모든 언어를 지원합니다. 중첩된 블록 수준 요소(예: P, DIV)를 지원합니다.
