Stupid question about abstract classes?

Question

PHP

Could you explain to me how abstract classes work directly in PHP?
Let's assume I have an abstract class Parent in which connection to a DB is carried out.
There are 10 child classes that inherit from Parent.
If I create 10 objects from each child class on the page, does that mean I will have 10 db connections?

Answer 1

If you create 10 objects from each of the 10 child classes, then you will have 100 connections.
