Another exaple, where IMHO it should work:
<?php
class Creator {
public $objects;
public function __get($name) {
if (!isset($this->objects[$name])) {
$this->objects[$name] = new $name($this);
}
return $this->objects[$name];
}
}
class Class1 {
public function __construct($Creat) {
echo 'Class1';
$Creat->Class2;
}
}
class Class2 {
public function __construct($Creat) {
echo 'Class2';
}
}
$Creat = new Creator;
$Creat->Class1;
?>
OUTPUT:
Class1
Notice: Undefined property: Creator::$Class2 in
D:\Server\www\noname\test.php on line 17
Expected:
Class1Class2

Interesting thing:
1) It should happen at all because using $this->B should result in an
implicitly declared proeprty.
2) It is expected behavior because __get/__set have a simple recursion
protection which disables __get/__set during __get/__set calls.

Description:
------------
When __get method accesses other property in some class, expected call
to __get method not occurs, undefined property notice appears and null
value of property returns.
Reproduce code:
---------------
<?PHP
class A
{
public function __get($property)
{
echo "__get()\n";
if ($property == "B")
return 1;
elseif ($property == "C")
return $this->B;
}
}
error_reporting(E_ALL);
$a = new A();
echo "B={$a->B}\n";
echo "C={$a->C}\n";
?>
Expected result:
----------------
__get()
B=1
__get()
__get()
C=1
Actual result:
--------------
__get()
B=1
__get()
Notice: Undefined property: A::$B in PHPDocument1 on line 12
C=
