Access private methods from outside a class

I have a Bcrypt.class which contains my hashing methods and I have a userDAO.class which contains my register method.

In my Bcrypt.class the methods are private. How can I access them in my userDAO.class so I can hash my password?

Please let me know if you need to see any code.

As of PHP 5.4 and ReflectionMethod::getClosure() it looks like accessing private methods from the outside is possible. To be honest - had to try out the following solution before believing it actually works.

Code from the User Contributed Notes section by Denis Doronin.

function call_private_method($object, $method, $args = array()) 
{
    $reflection = new ReflectionClass(get_class($object));
    $closure = $reflection->getMethod($method)->getClosure($object);
    return call_user_func_array($closure, $args);
}

class Example 
{

    private $x = 1;
    private $y = 10;

    private function sum() 
    {
        print $this->x + $this->y;
    }

}

call_private_method(new Example(), 'sum');

// Output is 11.

You cannot access private methods from outside of the class declaring them. If API developer decided to use private then there is no chance. I personally prefer protected in almost every situation. Some API developers don't..

If you have personal access to the source code of the Bcrypt class and you can change it without breaking anything then make the methods either protected and extend the class or make them even public

Another design approach would be to place the algorihms in a separate class and use them in the Bcrypt class and others

Make your methods in the Bcrypt class either public or protected.

These are things you should keep in mind.

  • Public Methods : Can be accessed from anywhere
  • Protected Methods : Can be accessed by the class and other classes that inherits it.
  • Private Methods : Only the corresponding will have access.
