What are some recommended steps for beginners to understand and implement OOP principles in PHP?

To understand and implement OOP principles in PHP, beginners can start by learning the basic concepts such as classes, objects, inheritance, encapsulation, and polymorphism. They can practice creating classes with properties and methods, extending classes, and using objects to interact with the classes. It's also important to understand how to use access modifiers like public, private, and protected to control the visibility of properties and methods. 

// Example of a simple class with properties and methods
class Car {
    private $brand;
    private $model;

    public function __construct($brand, $model) {
        $this->brand = $brand;
        $this->model = $model;
    }

    public function getBrand() {
        return $this->brand;
    }

    public function getModel() {
        return $this->model;
    }
}

// Creating an object of the Car class
$myCar = new Car("Toyota", "Corolla");

// Accessing properties and methods of the object
echo "Brand: " . $myCar->getBrand() . "<br>";
echo "Model: " . $myCar->getModel() . "<br>";
