Filling a PDF template with PHP

I have a PDF file that functions as a template containing on开发者_开发问答ly textboxes. Is there any way I can fill the fields in via PHP? I have found examples of how to directly draw onto a PDF document when given x,y values, but I want to put values into my textboxes rather than doing that.

Sourabh's link showed that this is impossible in Android, I'm reverting to using a HTML document with filler where the textboxs in the PDF were and replacing them in code.
