Problems with the Zend Framework PDF

Question

This again I guys, I have a little problem:

        // Create new PDF 
    $pdf = new Zend_Pdf(); 

    // Add new page to the document 
    $page = $pdf->newPage(Zend_Pdf_Page::SIZE_A4); 
    $pdf->pages[] = $page; 

    // Set font 
    $page->setFont(Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA), 20); 

    // Draw text 
    $page->drawText('Hello world!', 100, 510); 

    $this->getResponse()
         ->setHeader('Content-Disposition', 'attachment; filename=result.pdf')
         ->setHeader('Content-type', 'application/x-pdf');

    echo $pdf->render(); 

When I upload a file and try to open it, I get an error message that sounds like this:

format error: not pdf or damaged

My question is: What am I doing wrong?

Answer 1

If you try to open the file using a text editor (or a hex editor), what will you get?

Your PDF should contain only PDF data, not HTML or white space at the beginning or end.
