I have built a simple file manager where users can download any type of file such as pdf, word or gif files. I want all of them to download file rather than view it in browsers. The uploaded filenames are stored in database.

推荐答案

<?php
// We'll be outputting a PDF
header('Content-type: application/pdf');

// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');

// The PDF source is in original.pdf
readfile('original.pdf');
?>
