通过PHP将元数据添加到PDF [英] Adding metadata to PDF via PHP

问题描述

我需要使用PHP(5.3)下载时使用自定义元数据字段来扩展PDF.

I need to augment a PDF with a custom metadata field on download in PHP (5.3).

我一直在查看 pdftk 库，但是我无法理解如何我将让PHP在我们的(Ubuntu)Web服务器上与之交互.

I have been looking at the pdftk library, but I can't get my head around how I would get PHP to interface with it on our (Ubuntu) web server.

已弃用的PDFInfo库似乎是一个死胡同.

The deprecated PDFInfo library seems like a dead end.

有没有更简单/更容易/更好的解决方案?

Is there a simpler/easier/better solution?

谢谢

推荐答案

您可以使用

You could use Zend_Pdf. It's from the Zend Framework but can be used as a standalone component. Adding metadata is as easy as:

  $pdf = Zend_Pdf::load($pdfPath);
  $pdf->properties['Title'] = 'New Title.';
  $pdf->save($pdfPath);
