| PHP does not in fact allow function overloading, ie same name,
| different signature. But it does allow you to use optional variables,
| simply give them a default value in the parameters list.

| exponent($base, $power=2)
| {
| // operation
| }
i haven't checked this, but can't you extend a base class and give a
different signature for the same interface?
