How to do "friend class" in php?

[Yarco]

In c++ we could modify the private variable in a class use friend
keyword.
How could it be done in php?

class YourBag
{
int money;

friend class Thief; // friend?
};

There is no "friend" or package visibility. Sorry.

The comments on that page also include a rather nice way of implementing
friend classes yourself, though you may also want to overload __call().

Although a little more fiddly, the above method is arguably better than
C++'s. This is because with a little extra work you could define an
"acquaintan ce" class which is, say, the same as a friend class, but has
read-only access to object properties instead of read-write.

Using debug_backtrace to obtain the name of the calling class... well,
this is not what I'd actually call "nice". Looks quite ugly, but so is
the very idea of "friends", so it's fair, at least. ;)
