There are two methods that save changes to PDF documents: the Zend_Pdf::save()
and
Zend_Pdf::render()
methods.
Zend_Pdf::save($filename, $updateOnly = false)
saves the PDF document to a file. If $updateOnly
is true, then only the new PDF file segment is appended to a file. Otherwise, the file is overwritten.
Zend_Pdf::render($newSegmentOnly = false)
returns the PDF document as a string. If
$newSegmentOnly is true, then only the new PDF file segment is returned.
Example 40.3. Saving PDF Documents
... // Load the PDF document $pdf = Zend_Pdf::load($fileName); ... // Update the PDF document $pdf->save($fileName, true); // Save document as a new file $pdf->save($newFileName); // Return the PDF document as a string $pdfString = $pdf->render(); ...
