How to export and download files in php

header("Content-Type: application/vnd.ms-excel")

If you want to be able to provide the open/save dialog box, Content-Disposition parameter, Content-Disposition The parameter was originally intended to provide a suggested file name when the client saves a file, but for security reasons, this parameter was removed from the specification.

Content-Disposition parameters: attachment --- download as attachment inline --- Open online

Specific use:

header("Content-Disposition: inline; filename=filename.mp3");
Header("Content-Disposition: attachment;filename=test.xls");

In fact, IE identifies this file type based on the suffix of the file name in the filename section of Content-Disposition. If there are many file types, you can set Content-Type to binary mode: Header("Content-type: application/octet-stream");

Example:

$filename = './download/d.rar ';
$filesize = filesize($filename);
header( "Content-Type: application/force-download ");
 header( "Content-Disposition: attachment; filename= ".basename($filename));
header( "Content-Length: ".$filesize);
$data = file_get_contents($filename);
echo $data;
 ?>

The above code realizes that the download and save window will appear immediately after opening the page, and the downloaded file is $filename.

Some commonly used mimetype types:

$mimetypes = array( 'doc' => 'application/msword', 'bin' => 'application/octet-stream', 'exe' => 'application/octet-stream', 'so' => 'application/octet-stream', 'dll' => 'application/octet-stream', 'pdf' => 'application/pdf', 'ai' => 'application/postscript', 'xls' => 'application/vnd.ms-excel', 'ppt' => 'application/vnd.ms-powerpoint', 'dir' => 'application/x-director', 'js' => 'application/x-javascript', 'swf' => 'application/x-shockwave-flash', 'xhtml' => 'application/xhtml+xml', 'xht' => 'application/xhtml+xml', 'zip' => 'application/zip', 'mid' => 'audio/midi', 'midi' => 'audio/midi', 'mp3' => 'audio/mpeg', 'rm' => 'audio/x-pn-realaudio', 'rpm' => 'audio/x-pn-realaudio-plugin', 'wav' => 'audio/x-wav', 'bmp' => 'image/bmp', 'gif' => 'image/gif', 'jpeg' => 'image/jpeg', 'jpg' => 'image/jpeg', 'png' => 'image/png', 'css' => 'text/css', 'html' => 'text/html', 'htm' => 'text/html', 'txt' => 'text/plain', 'xsl' => 'text/xml', 'xml' => 'text/xml', 'mpeg' => 'video/mpeg', 'mpg' => 'video/mpeg', 'avi' => 'video/x-msvideo', 'movie' => 'video/x-sgi-movie', );
