用PHP传递存储在数据库中的文件数据时提示用户打开或保存

Posted 2021-02-26

This set of headers works for me when I output file data from the database for the user to save or open.

<?
header("content-type: $mime_type");
header("content-disposition: attachment; filename=$file_name");
header("cache-control: private");
header("pragma: private");
echo $file_data;
?>
