How is it customary to design objects according to some parameter?

Question

PHP

Good evening.
There is an object ID, and a class that characterizes the essence of the object. An instance of the class is created based on this ID (all data about the object, all parameters are filled). There are 2 options:
- do it in the constructor of the entity
- do it in the factory, and add everything to the class from the outside
What is the generally accepted approach if the design logic is complex?
Thanks in advance.
