Description:
------------
Good morning!
I've found what I'm reasonably certain is a bug, and I've searched to
verify that nobody has reported the same issue. I see some similar
issues reported by others, but I don't think any are identical.
Hopefully I'm not beating a dead horse.
The issue I've run into is that __get and __set cause odd behavior if
you're trying to get or set a piece of an array (e.g. $object->arr[1] =
true;). It returns back a notice: "Indirect modification of overloaded
property ClassName::$my_array has no effect" (and indeed it doesn't; the
assignment or retrieval do not work!).
You can get around this by assigning the entire array in advance and
then assigning the array as a unit to the object, and retrieving
similarly (the entire array first, then in pieces). However, it seems to
be the case that I should be able to assign pieces of arrays here just
like anywhere else.
As an additional note, if the array is an actual class property, it
works.
Thanks so much for your time!

Reproduce code:
---------------
<?php
class ClassName {
private $fields;
public $class_array;
public function __get($key) {
if (isset($this->fields[$key])) {
return $this->fields[$key];
}
else {
return null;
}
}
public function __set($key, $val) {
$this->fields[$key] = $val;
}
}
$c = new ClassName;
$c->scalar = 'two'; // works
$c->an_array[3] = 'three'; // throws notice
$diff_array[3] = 'three';
$c->diff_array = $diff_array; // works
$c->class_array[4] = 'four'; // works
Expected result:
----------------
I would have expected an assignment such as $c->an_array[3] = 'three';
to assign as expected.
It certainly seems intuitive that one should be able to assign an array
in this manner, and I saw nothing in the documentation indicating
otherwise. An array as a whole can be stored this way (as the second
working example indicates); there just seems to be something about
assigning a particular piece that breaks.
Incidentally, retrieving suffers from the same issue...I can retrieve
the array as a whole, but not a piece of it.
Actual result:
--------------
I get an error of level E_NOTICE: Indirect modification of overloaded
property ClassName::$an_array has no effect. The assignment or
retrieval, as the notice indicates, does not work.
