I have one .pdf file and I want to read with this file using PHP. and I know that i need pdf library for do that but i haven't any information about that so, please give me detail info for that library also...!
The way I did it was creating a desktop application with an IE control; load the PDF, programmatically right click on the document and copy. Then parse the copied contents using regular expressions. However, there is room for a lot of mistakes in this approach. Also, the author of the PDF can set the text in the document not selectable. In such scenario, this approach will not work.
One more alternative is to grab a snapshot of the document and parse the bitmap to detect the text in the bitmap. This again is a tedious job .... out of my radar :)
