How to get multiple objects of the same model?

Question

PHP

There is a simple class

class Book
{
  public $id;
  public $name;
    
  public function __construct(int $id, string $name){
    $this->id = $id;
    $this->name = $name;
  }

  //и тд.
}

In conjunction with the collection class, you can get many objects of the same model.
And it is possible, by changing the class, to return a set of objects inside the given one.
What is the best and most convenient way?
