How do I use php to edit a pdf file? Specifically, I would like to upload a pdf file, find a specified string of text (e.g. Google) and replace it with another string (e.g. Yahoo). Then, print a link to download the new pdf.
Thus from file1.pdf:
A good search engine would be Google.
file2.pdf is created:
A good search engine would be Yahoo.
Furthermore, is it also possible to do this and change the hyperlink as well?
i have ever met the same problem, but i solved it by another way. You can load the expored PDF file to Adobe Acrobat Pro for editing, It would be OK. From my experience, I like to use Word to edit my contents and after finishing that work, I would save Word as PDF using Cute PDF Writer or Office 2007 add-in. If I found some mistakes need to modified in the PDF format, I would edit the contents in the original word process and then save it as PDF again, and again. Actually I don't like to use Acrobat for creating ebook. It is not easy to learn well. I just use it to edit some details when I don't want to save all again. Of course, different guy has his own way. There is another way, known as the article How to edit PDF text , you would take it for reference.
