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);;
- }

说明：
以上实现一个函数forceDownload()，然后通过调用该函数即可实现php强制下载文件。
