Kimmo,

Thank for for the answer, but what I mean is a little bit different. I
want to simplify the following construction:

function CreateClass($className) {
switch (func_num_args()) {
case 1:
return new $className();
case 2:
return new $className(func_get_arg(1));
case 3:
return new $className(func_get_arg(1), func_get_arg(2));
...
}
}

In other words, I want something like:
function CreateClass($className) {
return create_user_class_array($className, array_shift($a =
func_get_args()));
}

Where create_user_class_array is the "magic" method similar to
call_user_func_array, which, I hope, should exist and I just did not
find it... But now I almost sure that there is no such method.

Thanks,
Alexander
