Restricting function call to within a class

[Geee]

Is there any way to restrict a function so that it can only be called from the class that it is declared in? This might not be very well explained so I will give an example...

class example {

  function a () {
    echo 'a!';
  }

  function b () {
    echo 'b!';
    $this->a();
  }

}

So you can do...
$example = new example;
$example->a();
$example->b();

and both would work fine. But if I wanted function a to only be called from within function b - would that be possible?

Maybe. If you are running PHP v. 5, you could declare the method private.

With PHP v. 4, there is no such mechanism built in.
