Unable to download pdf file from the server in codeigniter

I am using the following codes in my controller to download pdf files which are stored in a folder inside application folder in codeigniter. In the view page I have a button, upon clicking it, it redirects to this controller and then it download the file. It downloads blank page(pdf). Looking forward to any suggestion. 

 $filePath = APPPATH.'invoice/'."Let's Sunday#".$this->uri->segment(4).".pdf";
        if(!empty($filePath) && file_exists($filePath)){ 
        header("Content-Type: application/octet-stream");
        header("Content-Disposition: attachment; filename=" .$filePath); 
        header("Content-Type: application/octet-stream");
        header("Content-Type: application/download");
        header("Content-Description: File Transfer");            
        header("Content-Length: " . filesize($filePath));
        flush(); 
        $fp = fopen($filePath, "r");
        while (!feof($fp))
        {
            echo fread($fp, 65536);
            flush(); 
        } 
        fclose($fp); }else{echo "file does not exist";}

Here is what I have in a download section within a CodeIgniter app: 

if (file_exists($filePath)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="'.basename($filePath).'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($filePath));
    readfile($filePath);
    flush(); 
    exit;
}

The differences are in the ordering of the headers (which likely doesn't matter), the inclusion of the expires and pragma headers, and the Content-Disposition using the full basename.

The naming convention on that PDF filename might cause an issue...something else to test out.

Change the name in Content-Disposition to filename only instead of full path
