Read / retrieve data from PDF files

Dear Friends,

I posted this query 4 days ago and I am still waiting for the reply from you all. I really need your support.......plz

I have some pdf files on my database/FTP. Is there any process so that I can retrieve data from those pdf files with some search keywords?

I need the same result as we get on google. Is this possible in PHP?

Please advice.........

Thanks
Deepak

You may need to employ some third-party tools. This site lists quite a few, you may also look at PowerGrep, and run a Google query on something like "text search pdf" - it will give you some tools to consider.

Essentially, a PDF is gzipped XML. Using this knowledge you could write a tool to correctly uncompress and analyze the data.
Or you could use free tools like FPDF and FPDI.
