// The file that will be sent to the user
$your_file = 'file.zip';
// Rename the file name
$new_file = 'new-filename.zip';
// Set the download speed limit (70 kb/s)
$download_speed = 70;

if(file_exists($myl_file) && is_file($my_file)) {
    // Headers
    header('Cache-control: private');
    header('Content-Type: application/octet-stream');
    header('Content-Length: '.filesize($my_file));
    header('Content-Disposition: filename='.$new_file);
    // Flush the content
    flush();
    // File stream
    $file = fopen($my_file, "r");
    while (!feof($file)) {
        // Send the current part of the file to the browser
        echo fread($file, round($download_speed* 1024));
        // Flush the content to the browser
        flush();
        // Sleep one second
        sleep(1);
    }
    // Close file stream
    fclose($file);
}

else {
    die('Error: The file '.$my_file.' does not exist!');
}

Use this scriprt for limit bandwidth speed or you can also use QoS Bandwidth Throttle in PHP.
