I want to save in pdf format, but when i try to save i have an error response from phpexcel: Fatal error: Uncaught exception 'PHPExcel_Writer_Exception' with message 'Unable to load PDF Rendering library' in C:xampphtdocsfservClassesPHPExcelWriterPDFDomPDF.php:34 Stack trace: #0 C:xampphtdocsfservesportatore.php(190): include_once() #1 C:xampphtdocsfservindex.php(44): include('C:xampphtdocs...') #2 {main} thrown in C:xampphtdocsfservClassesPHPExcelWriterPDFDomPDF.php on line 34



You need DomPDF for rendering the PDF. Check if you have the DomPDF library, otherwise download and implement it as follow:

$rendererName = PHPExcel_Settings::PDF_RENDERER_DOMPDF;
$rendererLibrary = 'domPDF0.6.0beta3';
$rendererLibraryPath = dirname(__FILE__). 'libs/classes/dompdf' . $rendererLibrary;

I've used PHPExcel with CodeIgniter successfully before.

All I did was drop the phpexcel folder into application/third-party and created the following wrapper library:


class Excel {

    private $excel;

    public function __construct() {
        // initialise the reference to the codeigniter instance
        require_once APPPATH.'third_party/phpexcel/PHPExcel.php';
        $this->excel = new PHPExcel();    

    public function load($path) {
        $objReader = PHPExcel_IOFactory::createReader('Excel5');
        $this->excel = $objReader->load($path);

    public function save($path) {
        // Write out as the new file
        $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');

    public function stream($filename) {       
        header('Content-type: application/ms-excel');
        header("Content-Disposition: attachment; filename="".$filename."""); 
        header("Cache-control: private");        
        $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');

    public function  __call($name, $arguments) {  
        // make sure our child object has this method  
        if(method_exists($this->excel, $name)) {  
            // forward the call to our child object  
            return call_user_func_array(array($this->excel, $name), $arguments);  
        return null;  


I could then do the following in my controllers:

$this->excel->getActiveSheet()->SetCellValue('B2', "whatever");

Hope this helps you out?

The file that you've posted has a single space character before the PHPExcel output... check your script to see where this might be sent to the php://output stream. Check that there's no space before your initial <?php opening tag; watch out in particular for ?> <?php or similar closing/opening tags. And also check any files that might be included by your script

$fp = fopen($fileLocation, 'r');
$content = fread($fp, filesize($fileLocation));
$content = addslashes($content);

You can save the $content to blob field in mysql

I found the solution here

            var actionPDF = new Rotativa.ActionAsPdf("YOUR_ACTION_Method", new { id = ID, lang = strLang } //some route values)
                //FileName = "TestView.pdf",
                PageSize = Size.A4,
                PageOrientation = Rotativa.Options.Orientation.Landscape,
                PageMargins = { Left = 1, Right = 1 }
            byte[] applicationPDFData = actionPDF.BuildPdf(ControllerContext);
