If you creates methods by using classkit_method_add(), they are not visible in get_class_methods().

class A
{   
       public function foo()
       {
            return "foo!\n";
       }
}

classkit_method_redefine('A','bar','','return "bar !\n";',CLASSKIT_ACC_PUBLIC);

print_r(get_class_methods('A'));
// writes only "foo"
