why would you want to, is there a technical reason for wanting magic
functionality instead of "normal" functionality (+ wouldn't it make the
code much easier to maintain and debug if developers can see what is
called where, instead of just magic).
to answer though, you're best bet is probably to make an abstract class
with magic functionality and then extend with an implementing public class.
abstract class MagicUser
{
public function __call($name, $args)
{
//validate user....
$this->_validate();
$this->_{$name}($args);
}
private function _validate()
{
//....
}
private function _update($args)
{
//....
}
}
class User extends MagicUser
{
public function update($args)
{
parent::update($args);
}
}
