I think that the approach is incorrect here. You should think on a factory
pattern when using an anonymous/indirect way of creating an object.
Make a static factory method in class and call is with something like:
$obj =& call_user_function_array('Factory::createUser', array('bob',1234)));
and define:
class Factory {
function &createUser($name, $number) {
return new User($name, $number);
}
}
Of course you could abstract the factory method even further by passing the
classname, and making use of several options, from:
return new $className($par1, $par2);
to:
$o = new $className();
call_user_function_array(array(&$o, 'init'), array($par1, $par2));
return $o;
Or variations thereof, like passing an assoc array of params instead of
multiple params, to make thing more uniform.
A good place to read about and learn design patterns:
