Use PHP to force download PDF files Sample _php Tutorial

Source: Internet
Author: User
We sometimes encounter situations where downloading a PDF file without processing will open the PDF file directly in the browser and then save the download file by saving it. This article will be done by PHP to download PDF files directly.

Implementation principle: We just need to modify the page HTTP header, the Content-type set to Force-download, the problem can be resolved.

Please look at the code:
Copy CodeThe code is as follows:
Forcedownload ("Pdfdemo.pdf");
function Forcedownload ($filename) {

if (false = = File_exists ($filename)) {
return false;
}

HTTP headers
Header (' content-type:application-x/force-download ');
Header (' content-disposition:attachment; Filename= '. basename ($filename). ');
Header (' Content-length: '. FileSize ($filename));

For IE6
if (false = = = Strpos ($_server[' http_user_agent '), ' MSIE 6 ')) {
Header (' Cache-control:no-cache, Must-revalidate ');
}
Header (' Pragma:no-cache ');

Read file content and output
return ReadFile ($filename);;
}

For convenience, I wrote a function forcedownload () and then called the function.
