What APIs or libraries do you know for creating forms?

Question

PHP

The challenge is to find the right technology for, say, a site with a bunch of surveys. Moreover, polls can be completely diverse, forms can contain different elements, the number of acceptable well or minimum answers to questions can be different, well, and so on. and so on... Have you met any libraries that can produce usable web pages? And it doesn’t matter at all whether it’s a PEAR module, some kind of D3.js or something else .... after googling, I just found only the Google Froms API, and the Drupal Forms API, but no one will use Drupal. Help please, tell the dense what else happens)
PS: I write in PHP because PHP is used at work. In fact, in principle, it doesn’t matter what to write on, well, besides C ++ / CGI))
PS: Of course, I can write this myself with all the goodies, and in principle I'm going to, but now I need to quickly, quickly, as always
