    function getFunctions() {
        return get_class_methods(__CLASS__);
    }
    
    function test1() {
    }
}

class Bar extends Foo {
    function test2() {
    }
}

$bar = new Bar();
print_r($bar->getFunctions());

Expected result:
----------------
Array ( [0] => getFunctions [1] => test1 [2] => test2 ) 

Actual result:
--------------
Array ( [0] => getFunctions [1] => test1 )
