note 35538 deleted from function.header by kennyt

Note Submitter: Marquinhos ---- I have found that for certain formats, for example, PDF, the simple code: header("Content-type: application/x-download"); header("Content-Disposition: attachment; filename=$file_download_name;"); @readfile($file_server_path); does not work, and produces corrupted files for all browsers on all platforms. During the downloads, I noticed that the browser was not receiving ahead of time the length of the file, which was somehow causing some formats to be corrupted. e.g.: "Downloading file example.pdf: 347.2 KB of ?" I solved the problem by adding more headers: $download_size = filesize($file_server_path); header("Content-type: application/x-download"); header("Content-Disposition: attachment; filename=$file_download_name;"); header("Accept-Ranges: bytes"); header("Content-Length: $download_size"); @readfile($file_server_path); Somehow the files aren't corrupted when the browser knows how big they are from the start. I hope that helps :)
