What are some best practices for accessing protected and private methods within a class in PHP?

To access protected and private methods within a class in PHP, one common approach is to use reflection. Reflection allows you to inspect classes, properties, and methods at runtime, even if they are declared as protected or private. By using reflection, you can bypass the access restrictions and invoke these methods as needed. 

class MyClass {
    private function privateMethod() {
        return "This is a private method";
    }
}

$object = new MyClass();
$method = new ReflectionMethod('MyClass', 'privateMethod');
$method->setAccessible(true);
$result = $method->invoke($object);

echo $result; // Output: This is a private method
