Are there any best practices for improving code readability and understanding in PHP object-oriented programming, especially for beginners?

Issue: Beginners often struggle with understanding and reading object-oriented PHP code due to its complexity. One way to improve code readability and understanding is by following best practices such as using meaningful variable and method names, organizing code into logical classes and methods, and documenting code with comments. Code snippet: 

// Example of a well-commented and organized PHP class
class User {
    private $firstName;
    private $lastName;
    
    // Constructor method
    public function __construct($firstName, $lastName) {
        $this->firstName = $firstName;
        $this->lastName = $lastName;
    }
    
    // Getter method for first name
    public function getFirstName() {
        return $this->firstName;
    }
    
    // Getter method for last name
    public function getLastName() {
        return $this->lastName;
    }
}

// Example of creating a new User object and accessing its properties
$user = new User('John', 'Doe');
echo 'First Name: ' . $user->getFirstName() . '<br>';
echo 'Last Name: ' . $user->getLastName() . '<br>';
