Question

I’ve this sample code:

class A
{
 public function A_A() { /* ... */ }

 public function A_B() { /* ... */ }
}

class B extends A
{
 public function B_A() { /* ... */ }

 public function B_B() { /* ... */ }

 public function B_C()
 {
  return get_class_methods($this);
 }
}

$a = new A();
$b = new B();

Doing this:

echo '<pre>';
print_r($b->B_C());
echo '</pre>';

Yields the following output:

Array
(
    [0] => B_A
    [1] => B_B
    [2] => B_C
    [3] => A_A
    [4] => A_B
)

How can I make it return only the following methods?

Array
(
    [0] => B_A
    [1] => B_B
    [2] => B_C
)

I’ve a method in class A that should call all the methods in class B, the problem is of course that it leads to a infinite loop due to the values returned by get_class_methods().

You might need full strength Reflection. However, before you go there, it might be worth trying something like this.

array_diff(get_class_methods($this), get_class_methods(get_parent_class($this)))
