Support
I have been trying to use the PHP Libraries for PDFNEt, and have run into issues. The main issue I have is that the library refuses to load within PHP. I get error messages from PHP that the library is not valid. I am using the latest download for both OSX and Linux, neither of which seems to work. The “PDFNetPHP.so” does not ship with the Mac OSX version of PDFNet, but I did try to use the 64bit Linux version, and that did not work. Testing with Unbuntu 13 also failed to load the library. On OSX I am running Mavericks with PHP 5.4, on Ubuntu I am running PHP 5.5
Currently pre-built PHP bindings releases for PDFNet are only targeting PHP 5.3.6. Unfortunately PHP 5.5. extensions ABI is not compatible with 5.3.6.
We understand that this is a bit of an issue because not everyone will be using a specific version of PHP that we link with. Fortunately, we recently published the source code PHP binding so that you build the version you need. To get started,
