Entity and Repository - difference?

Question

Doctrine ORM

I started to dig into the project, I saw that there is work with the doctrine, Repository, Entity.
As I understand it, requests are mostly made in repositories, and entity simply describes the structure of the table? (I saw there columns like
private $id; ... and with some kind of annotations.
In general, in simple, human language, why do we need repositories and entities?

Answer 1

In simple terms (in fact, a little more complicated):
Entity is an entity, displaying one record in the database.
Reepository is a class for working with a table in a database, as an example, CRUD operations.
This separation allows you to implement the principle of single responsibility and makes the code a little better (compared to ActiveRecord, for example).
