Could you do something like this?

$private = "Myclass"
$protected = "*";

// public variable
echo $myclass["field1"];

// private variable
echo $myclass[$private."field2"];

// protected variable
echo $myclass[$protected."field3"];

Unless, of course, this behavior is not consistent. If it is a bug, then you
run the risk of it being fixed in the future. But if it is intended to be
that way, then this format should work regardless of what the member variable
names are.

No, because if I have a property called 'Myclassfield1', after
casting to an array I can't tell if it's private property called
'field1' or a public property called 'Myclassfield1'.

I think it's just plain wrong. Arrays should not try to be objects.
You can find out protection level of a property via introspection of
the object that you have in hand. In the vast majority of cases,
you'll want it to act just like the docs say it does, and if you
don't, you should probably be using the object itself anyway.
