How rotate a pdf document using php?

Question

How can I rotate a pdf document using php and linux?

Answer 1

You would have to use a external library like this to extract the info a generate an image, then put it back to the pdf(or a new one)

EDIT: If your going to get a Logo or a diagram this is a good choice, if its a big document with text and lots of images... its going to be pretty hard, could you edit the OP with more info on what you need?
