What are some best practices for accessing methods of a parent class in PHP object-oriented programming?

When working with object-oriented programming in PHP, you may need to access methods of a parent class from a child class. To do this, you can use the `parent::` keyword followed by the method name to call the parent class method. This allows you to reuse code and avoid duplicating functionality in your child classes. 

class ParentClass {
    public function parentMethod() {
        echo "This is a method from the parent class.";
    }
}

class ChildClass extends ParentClass {
    public function childMethod() {
        parent::parentMethod();
    }
}

$child = new ChildClass();
$child->childMethod(); // Output: This is a method from the parent class.
