How data from a PHP form fill a ready-made template in pdf?

Question

PHP

A person fills out a form on the site and this information should be generated into a ready-made pdf, word template, so that the user does not manually fill out 10 forms with most of the same data. As I understand it, there are PHP libraries for this, but they create a new pdf template, and I need it to be ready-made, in which everything is already there. Most likely, you need to designate fields in pdf or word with variables, for example $ {name} But I don't know how to do this. Help, google can't help me with my situation
