You were talking to one of the core developers, so I don't see a reason
why you need another one to repeat the same.

in php5.1 all betas and RC1 __get and __set are ALSO called when trying
to access protected/private (invisible) properties.
btw, the manual describes php5, not php5.1 which is in beta/rc-stadium
...
so please forward this *bug* to the overload-developers!

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
Do you even read documentation? Getters and Setters can only be used to
access properties that are not declared in the class.

do you even read the bug-reports ?
by trying to set a private-property __get/__set are triggered in php5.1
(yes, it already works!) but there is a serious problem if using __get
AND __set together in a chain!

$a->p = $b; is the problem line, you are trying to access a private
property from outside the object, this is disallowed.

Description:
------------
chaining of objects using __get() works like a charm, however if using
chaining and using __set() at the end of the chain to set a property,
php fails reporting: "Fatal error: Cannot access private property A::$p
in <file> on line <line>"
please keep in mind that i'm using php5.1 (RC1), chaining should work
in this version, doesn't it?
posted reproduce code from
http://www.sitepoint.com/forums/showthread.php?p=2230679#post2230679
Reproduce code:
---------------
class A {
private $p;
function __get($name){
return $this->$name;
}
function __set($name, $value) {
$this->$name = $value;
}
}
class B {
private $t;
function __get($name){
return $this->$name;
}
function __set($name, $value) {
$this->$name = $value;
}
}
$a = new A;
$b = new B;
$a->p = $b;
$b->t = "foo";
echo $a->p->t;
$a->p->t = "bar";
echo $a->p->t;
Expected result:
----------------
foobar
Actual result:
--------------
foo
Fatal error: Cannot access private property A::$p in...
