Really a big fan of your solution and appreciate what you've done for PDF processing in the PHP realm. One of the strongest advantages I've seen in this solution is that it handles form fields appropriately versus disabling them. One thing I noticed was that the 1.10 change fixed the issue of merging PDFs and having "duplicate" fields, however I am using Adobe Acrobat 9 to do so and therefore assume it's a legitimate case. If this is a legitimate case, would you be able to add a command line argument that allows for disabling the renaming feature? I am desperately in need of a build that allows for echoing a field through merged pages.
Again - great job with this and really hope you're able to support this amazing tool!
