Yeah. PHP's fundamental OO credentials are very poor in general
for many reasons that unfortunately are in ways that are not
fixable without completely replacing the language because of
really basic stuff like so much being in the global namespace,
it's reliance so heavily on global variables, etc, and
developers who work with PHP and have not come from a language
that does a decent job of OO can't really be expected to know
much different. I'm hoping to get back to C++ soon.

Ya friend functions would be a nice thing.
as PHP doesn't support many interesting keys of OOPS like Template,
friend etc..
(I know Java doesn't support most of them too, But thats not a good
excuse, cause
in PHP some of this can be supported with minimum change in Code) Its
not
possible to maintain Proper Coding Standard. and Programmers are forced
code in a
bad way. designing patterns/idioms cannot be followed.

Long ago we decided against 'friend' declarations.

I'm developing an OOP CMS, too. This feature is really elementary for
complex systems where you want to limit access to the internals.
Currently I developed a system to access protected methods from outside
(using one base-class, a list to control the access and some secure
handshake when accessing the method), but thats detouring. Would be nice
to see some friend-system (like C++, or package -systemlike Java) in
PHP6.
If someone is interested in the code I mentioned above, I can post it.

I'm developing an OOP CMS, and the lack of friend objects prevents me
from disallowing layouts access to unsafe internal variables. It's
actually a rather severe problem when you try writing an advanced
system.

In PHP 5.1, it is possible to simulate the function of friend classes
with __get and __set (I think PHP 5.0 triggers an error when trying to
access private properties even with __get or __set):
class HasFriends
{
private $__friends = array('MyFriend', 'OtherFriend');
public function __get($key)
{
$trace = debug_backtrace();
if(isset($trace[1]['class']) && in_array($trace[1]['class'],
$this->__friends)) {
return $this->$key;
}
// normal __get() code here
trigger_error('Cannot access private property ' . __CLASS__ .
'::$' . $key, E_USER_ERROR);
}
public function __set($key, $value)
{
$trace = debug_backtrace();
if(isset($trace[1]['class']) && in_array($trace[1]['class'],
$this->__friends)) {
return $this->$key = $value;
}
// normal __set() code here
trigger_error('Cannot access private property ' . __CLASS__ .
'::$' . $key, E_USER_ERROR);
}
}
