Why dont you just inherit an abstract class?

PHP Code:


			
<?
abstract class a
{
    public function func($param)
    {
        echo "$param";
    }
}

class b extends a
{
    public $variable;
}

$instance = new b;
$instance->variable = "hello there";
$instance->func($instance->variable);
?>

Class A cannot be called as an instance because it is abstract, therefore then only class that can use func() is B, or any class that extends A.

Note: You must have PHP5 to do this, php4 doesnt support abstraction if I recall
