如何使用PHP从PDF文件中提取文本？

Question

I know there are a lot of PDF extraction methods/techniques, but I'm after a reliable text extractor for PDFs in PHP. All I want is to extract words, but not numbers and no special characters.

Any ideas of solid techniques to achieve this?

Answer 1

The Zend Framework provides Zend_Pdf, a php class that will load and parse pdf documents.

Here is a script that shows how to extract the text from a loaded Zend_Pdf object.
