"; Die () ;}$ fp = fopen ($ path, 'r'); // open $ filesize = filesize ($ path) in read-only mode ); // file size // returned File (stream form) header ("Content-type: application/octet-stream"); // return header ("Accept-Ranges: bytes "); // return the file size header (" Accept-Length: $ filesize "); // in the displayed dialog box on the client, the corresponding file name header (" Content-Disposition: attachment; filename = ". $ filename ); // ============================================================== ob_clean (); flush (); // ============================ ================/// Set the shunting $ buffer = 1024; // bytes counter for the next file $ count = 0; while (!
