$ Filename = iconv ('utf-8', 'gb2312', $ fname); $ path = $ fpath. $ filename; if (! File_exists ($ path) {// check whether the file exists
Echo "the file does not exist! "; Die ();
} $ Fp = fopen ($ path, 'r'); // read-only mode
$ Filesize = filesize ($ path); // file size

// Returned File (stream format)
Header ("Content-type: application/octet-stream"); // returns the value in bytes.
Header ("Accept-Ranges: bytes"); // returns the file size
Header ("Accept-Length: $ filesize"); // The pop-up dialog box of the client, the corresponding file name
Header ("Content-Disposition: attachment; filename = ". $ filename ); // =======================================================
Ob_clean ();
Flush (); // ==========================================================
// Set Traffic Distribution
$ Buffer = 1024; // The byte counter of the specified file.
$ Count = 0; while (! Feof ($ fp) & ($ filesize-$ count> 0) {$ data = fread ($ fp, $ buffer); $ count + = $ data; // count
Echo $ data; // send data to the browser
}

Fclose ($ fp );
