Internal in what way? And why?

I'm not sure I understood the above, but if I understood it right, why would
that be?
class SomeClass
{
function operator++() // #1
{
return ++$this->value;
}
function operator($dummy) // #2 ***
{
return $value++;
}
var $value;
}
$object=new SomeClass();
++$object; // Calls #1
$object++; // Calls # 2
(***) This is how it's done in C++ (actually, a dummy int parameter), which
is a bit of a hack, to be able to specify both the pre- and
post-increment/decrement operators. #2 (and postfix "--") is the "odd" one,
since they are the only postfix operators among the operators.
