What is the difference between PUT and PATCH?

Question

PHP

I am writing an API application. I read the documentation in English, but since I'm bad with it (English), it's not entirely clear how to use PUT and PATCH.

PUT seems to be clear, an entity is selected from the database and its fields are updated, and everything at once.

PATCH, the same, only not all fields are updated, but selectively.

Correct me if I'm wrong.
Thank you.
