Con questo script possiamo limitare il download di un file dal nostro server php; il limite di velocitá é dato dal parametro fread insrito in un print tramite la funzione flush();
// local file that should be send to the client $local_file = 'test-file.zip'; // filename that the user gets as default $download_file = 'your-download-name.zip'; // set the download rate limit (=> 20,5 kb/s) $download_rate = 20.5; if(file_exists($local_file) && is_file($local_file)) { // send headers header('Cache-control: private'); header('Content-Type: application/octet-stream'); header('Content-Length: '.filesize($local_file)); header('Content-Disposition: filename='.$download_file); // flush content flush(); // open file stream $file = fopen($local_file, "r"); while(!feof($file)) { // send the current file part to the browser print fread($file, round($download_rate * 1024)); // flush the content to the browser flush(); // sleep one second sleep(1); } // close file stream fclose($file);} else { die('Error: The file '.$local_file.' does not exist!'); }
