List all methods of a given class, excluding parent class's methods in PHP

Question

I'm building a unit testing framework for PHP and I was curious if there is a way to get a list of an objects methods which excludes the parent class's methods. So given this:

class Foo
{

    public function doSomethingFooey()
    {
        echo 'HELLO THERE!';
    }
}

class Bar extends Foo
{
    public function goToTheBar()
    {
        // DRINK!
    }
}

I want a function which will, given the parameter new Bar() return:

array( 'goToTheBar' );

WITHOUT needing to instantiate an instance of Foo. (This means get_class_methods will not work).

Answer 1

Use ReflectionClass, for example:

$f = new ReflectionClass('Bar');
$methods = array();
foreach ($f->getMethods() as $m) {
    if ($m->class == 'Bar') {
        $methods[] = $m->name;
    }
}
print_r($methods);

Answer 2

You can use get_class_methods() without instantiating the class:

$class_name - The class name or an object instance.

So the following would work:

$bar_methods = array_diff(get_class_methods('Bar'), get_class_methods('Foo'));

Assuming there aren't repeated methods in the parent class. Still, Lukman's answer does a better job. =)
