Php script and PDF / FPDF

[Amorgos]

Any advice how to start this project I will appreciate!

We have a PDF form posted on our web site and we like when a user
submit the complete form, data to be back to us as FDF or PDF using
some php script.
where I can find a PHP script to start...
There is any tutorial or a book you suggest to buy!

Thank very much

FPDF and FPDI are a good place to start.
