Fill data to pre-existing PDF form with php codes

[mynetworksolut]

I have an existing PDF form that has 3 fields in it to collect data from a user. Those 3 fields have 3 different names, I use PHP to collect data and store in mySQL, they all work fine.
Now how do I insert those data back to that existing PDF form if the user wants to review it with the data they've just typed in.

All answers are highly appreciated.

I use the flatten / fdf functions from PDFTK (http://www.accesspdf.com/pdftk/)
