The code in my comment works perfectly fine.
>Can't PHP internally do "$this->test = array()"?
No, it can't do your job for you. You have to do it in the __get()
method.

Description:
------------
If a member of an object is not defined and "gets initialized" by
PHP after/during the overloading process, a notice ("Indirect
modification of overloaded property") gets triggered when PHP has to
initialize it as an array type.
It makes no difference, if __get() returns by reference instead (a
ref to a null value), as Tony stated in
http://bugs.php.net/bug.php?id=40823 (the code in
his comment does
not work (anymore?)).
Background: we have a base class "Plugin" in our project and it uses
__get() for some properties and returns null otherwise.
Now, if some user-created plugin does
$this->foo[] = 'bar'
it will create this notice - which is quite confusing (if the
derived plugin does not "init" $foo with "var $foo").
Can't PHP internally do "$this->test = array()"?
(This may likely be a dupe of http://bugs.php.net/bug.php?id=39337 -
but that one got quite confusing, so this one here may become
a "reference bogus bug" for this issue at least.)
Reproduce code:
---------------
<?php
class A
{
function __get($name)
{
echo "__get() called.\n";
}
function A()
{
$this->test[] = 'foo';
}
}
$A = new A();
?>
Expected result:
----------------
__get() called.
Actual result:
--------------
__get() called.
Notice: Indirect modification of overloaded property A::$test has no
effect in foo.php on line 12
