How can PHP classes be structured to ensure better code readability and maintainability?

PHP classes can be structured to ensure better code readability and maintainability by following the principles of SOLID design. This includes breaking down classes into smaller, more focused components, using inheritance and interfaces effectively, and adhering to the single responsibility principle. By organizing code in a clear and logical manner, it becomes easier to understand, maintain, and extend.

class User {
    private $id;
    private $name;
    
    public function __construct($id, $name) {
        $this->id = $id;
        $this->name = $name;
    }
    
    public function getId() {
        return $this->id;
    }
    
    public function getName() {
        return $this->name;
    }
}
