파일 다운로드 프롬프트 구현 및 저장을 위한 헤더 기능 사용법에 대한 자세한 설명-PHP 튜토리얼-php.cn

파일 다운로드 기능을 구현할 때 많은 사람들이 이런 상황에 직면하게 될 것이라고 생각합니다. 원래 의도는 다운로드 링크를 클릭하여 저장 대화 상자를 표시하는 것이지만, 예를 들어 PDF와 같은 파일은 직접 표시됩니다. 저장하라는 메시지가 표시되는 대신 브라우저에 파일 콘텐츠가 표시됩니다. 이 문제는 다음 방법으로 해결할 수 있습니다.

<?php 
$filename = &#39;路径+实际文件名&#39;; 
//文件的类型 
header(&#39;Content-type: application/pdf&#39;); 
//下载显示的名字 
header(&#39;Content-Dis
position
: attachment; filename="保存时的文件名.pdf"&#39;); 
readfile("$filename"); 
exit(); 
?>

로그인 후 복사

다음은 인터넷에서 흔히 사용되는 방법입니다

if (isset($link)) 
{ 
  Header("HTTP/1.1 303 See Other"); 
  Header("Location: $link"); 
  exit; 
}

로그인 후 복사

$link就是文件的实际路径。
